Noninsertional Achilles Tendinitis

In noninsertional Achilles tendinitis, fibers in the middle portion of the tendon have begun to break down with tiny tears (degenerate), swell, and thicken.

Tendinitis of the middle portion of the tendon more commonly affects younger, active people.

Insertional Achilles Tendinitis

Insertional Achilles tendinitis involves the lower portion of the heel, where the tendon attaches (inserts) to the heel bone.

In both noninsertional and insertional Achilles tendinitis, damaged tendon fibers may also calcify (harden). Bone spurs (extra bone growth) often form with insertional Achilles tendinitis.

Tendinitis that affects the insertion of the tendon can occur at any time, even in patients who are not active.

Insertional Achilles tendinitis

X-rays

X-ray tests provide clear images of bones. X-rays can show whether the lower part of the Achilles tendon has calcified, or become hardened. This calcification indicates insertional Achilles tendinitis. In cases of severe noninsertional Achilles tendinitis, there can be calcification in the middle portion of the tendon, as well.

Magnetic Resonance Imaging (MRI)

Although magnetic resonance imaging (MRI) is not necessary to diagnose Achilles tendinitis, it is important for planning surgery. An MRI scan can show how severe the damage is in the tendon. If surgery is needed, your doctor will select the procedure based on the amount of tendon damage.

Nonsurgical Treatment

In most cases, nonsurgical treatment options will provide pain relief, although it may take a few months for symptoms to completely subside. Even with early treatment, the pain may last longer than 3 months. If you have had pain for several months before seeking treatment, it may take 6 months before treatment methods take effect.

Rest. The first step in reducing pain is to decrease or even stop the activities that make the pain worse. If you regularly do high-impact exercises (such as running), switching to low-impact activities will put less stress on the Achilles tendon. Cross-training activities such as biking, elliptical exercise, and swimming are low-impact options to help you stay active.

Ice. Placing ice on the most painful area of the Achilles tendon is helpful and can be done as needed throughout the day. This can be done for up to 20 minutes and should be stopped earlier if the skin becomes numb. A foam cup filled with water and then frozen creates a simple, reusable ice pack. After the water has frozen in the cup, tear off the rim of the cup. Then rub the ice on the Achilles tendon. With repeated use, a groove that fits the Achilles tendon will appear, creating a “custom-fit” ice pack.

Non-steroidal anti-inflammatory medication. Drugs such as ibuprofen and naproxen reduce pain and swelling. They do not, however, reduce the thickening of the degenerated tendon. Using the medication for more than 1 month should be reviewed with your primary care doctor.

Exercise. The following exercise can help to strengthen the calf muscles and reduce stress on the Achilles tendon.

• Calf stretch
  Lean forward against a wall with one knee straight and the heel on the ground. Place the other leg in front, with the knee bent. To stretch the calf muscles and the heel cord, push your hips toward the wall in a controlled fashion. Hold the position for 10 seconds and relax. Repeat this exercise 20 times for each foot. A strong pull in the calf should be felt during the stretch.

Physical Therapy. Physical therapy is very helpful in treating Achilles tendinitis. It has proven to work better for noninsertional tendinitis than for insertional tendinitis.

Eccentric Strengthening Protocol. Eccentric strengthening is defined as contracting (tightening) a muscle while it is getting longer. Eccentric strengthening exercises can cause damage to the Achilles tendon if they are not done correctly. At first, they should be performed under the supervision of a physical therapist. Once mastered with a therapist, the exercises can then be done at home. These exercises may cause some discomfort, however, it should not be unbearable.

• • Bilateral heel drop
    Stand at the edge of a stair, or a raised platform that is stable, with just the front half of your foot on the stair. This position will allow your heel to move up and down without hitting the stair. Care must be taken to ensure that you are balanced correctly to prevent falling and injury. Be sure to hold onto a railing to help you balance.

Lift your heels off the ground then slowly lower your heels to the lowest point possible. Repeat this step 20 times. This exercise should be done in a slow, controlled fashion. Rapid movement can create the risk of damage to the tendon. As the pain improves, you can increase the difficulty level of the exercise by holding a small weight in each hand.

• Single leg heel drop
  This exercise is performed similarly to the bilateral heel drop, except that all your weight is focused on one leg. This should be done only after the bilateral heel drop has been mastered.

Cortisone injections. Cortisone, a type of steroid, is a powerful anti-inflammatory medication. Cortisone injections into the Achilles tendon are rarely recommended because they can cause the tendon to rupture (tear).

Supportive shoes and orthotics. Pain from insertional Achilles tendinitis is often helped by certain shoes, as well as orthotic devices. For example, shoes that are softer at the back of the heel can reduce irritation of the tendon. In addition, heel lifts can take some strain off the tendon.

Heel lifts are also very helpful for patients with insertional tendinitis because they can move the heel away from the back of the shoe, where rubbing can occur. They also take some strain off the tendon. Like a heel lift, a silicone Achilles sleeve can reduce irritation from the back of a shoe.

If your pain is severe, your doctor may recommend a walking boot for a short time. This gives the tendon a chance to rest before any therapy is begun. Extended use of a boot is discouraged, though, because it can weaken your calf muscle.

Extracorporeal shockwave therapy (ESWT). During this procedure, high-energy shockwave impulses stimulate the healing process in damaged tendon tissue. ESWT has not shown consistent results and, therefore, is not commonly performed.

ESWT is noninvasive—it does not require a surgical incision. Because of the minimal risk involved, ESWT is sometimes tried before surgery is considered.

Surgical Treatment

Surgery should be considered to relieve Achilles tendinitis only if the pain does not improve after 6 months of nonsurgical treatment. The specific type of surgery depends on the location of the tendinitis and the amount of damage to the tendon.

Gastrocnemius recession. This is a surgical lengthening of the calf (gastrocnemius) muscles. Because tight calf muscles place increased stress on the Achilles tendon, this procedure is useful for patients who still have difficulty flexing their feet, despite consistent stretching.

In gastrocnemius recession, one of the two muscles that make up the calf is lengthened to increase the motion of the ankle. The procedure can be performed with a traditional, open incision or with a smaller incision and an endoscope—an instrument that contains a small camera. Your doctor will discuss the procedure that best meets your needs.

Complication rates for gastrocnemius recession are low, but can include nerve damage.

Gastrocnemius recession can be performed with or without débridement, which is removal of damaged tissue.

Débridement and repair (tendon has less than 50% damage). The goal of this operation is to remove the damaged part of the Achilles tendon. Once the unhealthy portion of the tendon has been removed, the remaining tendon is repaired with sutures, or stitches to complete the repair.

In insertional tendinitis, the bone spur is also removed. Repair of the tendon in these instances may require the use of metal or plastic anchors to help hold the Achilles tendon to the heel bone, where it attaches.

After débridement and repair, most patients are allowed to walk in a removable boot or cast within 2 weeks, although this period depends upon the amount of damage to the tendon.

Débridement with tendon transfer (tendon has greater than 50% damage). In cases where more than 50% of the Achilles tendon is not healthy and requires removal, the remaining portion of the tendon is not strong enough to function alone. To prevent the remaining tendon from rupturing with activity, an Achilles tendon transfer is performed. The tendon that helps the big toe point down is moved to the heel bone to add strength to the damaged tendon. Although this sounds severe, the big toe will still be able to move, and most patients will not notice a change in the way they walk or run.

Depending on the extent of damage to the tendon, some patients may not be able to return to competitive sports or running.

Recovery. Most patients have good results from surgery. The main factor in surgical recovery is the amount of damage to the tendon. The greater the amount of tendon involved, the longer the recovery period, and the less likely a patient will be able to return to sports activity.

Physical therapy is an important part of recovery. Many patients require 12 months of rehabilitation before they are pain-free.

Complications. Moderate to severe pain after surgery is noted in 20% to 30% of patients and is the most common complication. In addition, a wound infection can occur and the infection is very difficult to treat in this location.

Osteoarthritis

Osteoarthritis, also known as degenerative or “wear-and-tear” arthritis, is a common problem for many people after they reach middle age, but it may occur in younger people, too.

In osteoarthritis, the cartilage in the joint gradually wears away. As the cartilage wears away, it becomes frayed and rough, and the protective space between the bones decreases. This can result in bone rubbing on bone, and produce painful osteophytes (bone spurs).

In addition to age, other risk factors for osteoarthritis include obesity and family history of the disease.

Osteoarthritis develops slowly, causing pain and stiffness that worsen over time.

Rheumatoid Arthritis

(Top) Osteoarthritis that has progressed to bone rubbing on bone and bone spurs. (Bottom) Swollen, inflamed synovium and joint deformity are signs of rheumatoid arthritis.

Rheumatoid arthritis is a chronic disease that can affect multiple joints throughout the body, and often starts in the foot and ankle. It is symmetrical, meaning that it usually affects the same joint on both sides of the body.

Rheumatoid arthritis is an autoimmune disease. This means that the immune system attacks its own tissues. In rheumatoid arthritis, immune cells attack the synovium covering the joint, causing it to swell. Over time, the synovium invades and damages the bone and cartilage, as well as ligaments and tendons, and may cause serious joint deformity and disability.

The exact cause of rheumatoid arthritis is not known. Although it is not an inherited disease, researchers believe that some people have genes that make them more susceptible. There is usually a “trigger,” such as an infection or environmental factor, which activates the genes. When the body is exposed to this trigger, the immune system begins to produce substances that attack the joints.

Posttraumatic Arthritis

Posttraumatic arthritis can develop after an injury to the foot or ankle. Dislocations and fractures—particularly those that damage the joint surface—are the most common injuries that lead to posttraumatic arthritis. Like osteoarthritis, posttraumatic arthritis causes the cartilage between the joints to wear away. It can develop many years after the initial injury.

An injured joint is about seven times more likely than an uninjured joint to become arthritic, even if the injury is properly treated. In fact, following an injury, your body may actually secrete hormones that stimulate the death of your cartilage cells.

Physical Examination

Your doctor will discuss your overall health and medical history and ask about any medications you may be taking. He or she will examine your foot and ankle for tenderness and swelling and ask questions to understand more about your symptoms. These questions may include:

• When did the pain start?
• Where exactly is the pain? Does it occur in one foot or in both feet?
• When does the pain occur? Is it continuous, or does it come and go?
• Is the pain worse in the morning or at night? Does it get worse when walking or running?

Your doctor will also ask if you have had an injury to your foot or ankle in the past. If so, he or she will discuss your injury, including when it occurred and how it was treated.

Your doctor will also examine your shoes to determine if there is any abnormal or uneven wear and to ensure that they are providing sufficient support for your foot and ankle.

Gait analysis. During the physical examination, your doctor will closely observe your gait (the way you walk). Pain and joint stiffness will change the way you walk. For example, if you are limping, the way you limp can tell your doctor a lot about the severity and location of your arthritis.

During the gait analysis, your doctor will assess how the bones in your leg and foot line up when you walk, measure your stride, and test the strength of your ankles and feet.

Tests

This x-ray reveals osteoarthritis in the metatarsophalangeal joint of the big toe. Joint space narrowing (black arrow) and bone spurs (white arrows) can be seen.

X-rays. These imaging tests provide detailed pictures of dense structures such as bone. An x-ray of an arthritic foot may show narrowing of the joint space between bones (an indication of cartilage loss), changes in the bone (such as fractures), or the formation of bone spurs.

Weight-bearing x-rays are taken while you stand. They are the most valuable additional test in diagnosing the severity of arthritis and noting any joint deformity associated with it. In arthritic conditions, if x-rays are taken without standing, it is difficult to assess how much arthritis is present, where it is located in the joint, and how much deformity is present. So, it is very important that, when possible, x-rays are taken standing.

Other imaging tests. In some cases, a bone scan, computed tomography (CT) scan, or magnetic resonance imaging (MRI) scan may be needed to determine the condition of the bone and soft tissues.

Laboratory tests. Your doctor may also recommend blood tests to determine which type of arthritis you have. With some types of arthritis, including rheumatoid arthritis, blood tests are important for an accurate diagnosis.

Your doctor may refer you to a rheumatologist if he or she suspects rheumatoid arthritis. Although your symptoms and the results from a physical examination and tests may be consistent with rheumatoid arthritis, a rheumatologist will be able to determine the specific diagnosis. There are other less common types of inflammatory arthritis that will be considered.

Nonsurgical Treatment

Initial treatment of arthritis of the foot and ankle is usually nonsurgical. Your doctor may recommend a range of treatment options.

Lifestyle modifications. Some changes in your daily life can help relieve the pain of arthritis and slow the progression of the disease. These changes include:

• Minimizing activities that aggravate the condition.
• Switching from high-impact activities (like jogging or tennis) to lower impact activities (like swimming or cycling) to lessen the stress on your foot and ankle.
• Losing weight to reduce stress on the joints, resulting in less pain and increased function.

Physical therapy. Specific exercises can help increase range of motion and flexibility, as well as help strengthen the muscles in your foot and ankle. Your doctor or a physical therapist can help develop an individualized exercise program that meets your needs and lifestyle.

Although physical therapy often helps relieve stress on the arthritic joints, in some cases it may intensify joint pain. This occurs when movement creates increasing friction between the arthritic joints. If your joint pain is aggravated by physical therapy, your doctor will stop this form of treatment.

A custom-molded leather brace can be effective in minimizing the pain and discomfort from ankle and hindfoot arthritis.

Assistive devices. Using a cane or wearing a brace—such as an ankle-foot orthosis (AFO)-may help improve mobility. In addition, wearing shoe inserts (orthotics) or custom-made shoes with stiff soles and rocker bottoms can help minimize pressure on the foot and decrease pain. In addition, if deformity is present, a shoe insert may tilt the foot of ankle back straight, creating less pain in the joint.

Medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, can help reduce swelling and relieve pain. In addition, cortisone is a very effective anti-inflammatory agent that can be injected into an arthritic joint. Although an injection of cortisone can provide pain relief and reduce inflammation, the effects are temporary.

Surgical Treatment

Your doctor may recommend surgery if your pain causes disability and is not relieved with nonsurgical treatment. The type of surgery will depend on the type and location of the arthritis and the impact of the disease on your joints. In some cases, your doctor may recommend more than one type of surgery.

Arthroscopic debridement. This surgery may be helpful in the early stages of arthritis. Debridement (cleansing) is a procedure to remove loose cartilage, inflamed synovial tissue, and bone spurs from around the joint.

The surgeon holds the arthroscope in his left hand and uses a thin instrument with his right hand to create another small incision.

During arthroscopy, your surgeon inserts a small camera, called an arthroscope, into your foot or ankle joint. The camera displays pictures on a television screen, and your surgeon uses these images to guide miniature surgical instruments. Because the arthroscope and surgical instruments are thin, your surgeon can use very small incisions (cuts), rather than the larger incision needed for a traditional, open surgery.

Arthroscopic surgery is most effective when pain is due to contact between bone spurs and the arthritis has not yet caused significant narrowing of the joint space between the bones. Arthroscopy can make an arthritic joint deteriorate more rapidly. Removing bone spurs may increase motion in the joint, causing the cartilage to wear away quicker.

Arthrodesis (fusion). Arthrodesis fuses the bones of the joint completely, making one continuous bone out of two or more bones. The goal of the procedure is to reduce pain by eliminating motion in the arthritic joint.

During arthrodesis, the doctor removes the damaged cartilage and then uses pins, plates and screws, or rods to fix the joint in a permanent position. Over time, the bones fuse or grow together, just like two ends of a broken bone grow together as it heals. By removing the joint, the pain disappears.

Screws are used to fuse the bones of the hindfoot and prevent painful motion.

Arthrodesis is typically quite successful, although there can be complications. In some cases, the joint does not fuse together (nonunion), and the hardware may break. This may happen if you put weight on your foot before the fusion is complete. While the broken hardware does not cause pain, the nonunion of the fusion can lead to pain and swelling. If nonunion occurs, a second operation to place bone graft in the ankle and place new hardware may be needed. However, repeated fusions are not as likely to be successful, so it is best to closely follow your doctor’s guidelines during the recovery period of your original operation.

A small percentage of patients have problems with wound healing, but these problems can usually be addressed by bracing or by an additional surgery. In some cases, loss of motion in the ankle after a fusion causes the joints adjacent to the one fused to bear more stress than they did before the surgery. This can lead to arthritis in the adjacent joints years after the surgery.

An x-ray of a total ankle replacement (arthroplasty)

Total ankle replacement (arthroplasty). In total ankle replacement, your doctor removes the damaged cartilage and bone, and then positions new metal or plastic joint surfaces to restore the function of the joint.

Although total ankle replacement is not as common as total hip or total knee replacement, advances in implant design have made it a viable option for many people.

Ankle replacement is most often recommended for patients who have:

• Advanced arthritis of the ankle
• Arthritis that has destroyed the ankle joint surfaces
• Ankle pain that interferes with daily activities

Ankle replacement relieves the pain of arthritis and offers patients more mobility and movement than fusion. In addition, being able to move the formerly arthritic joint means that less stress is transferred to the adjacent joints. This lessens the chance of developing adjacent joint arthritis.

As in any type of joint replacement, an ankle implant may loosen or fail over the years. If the implant failure is severe, the replaced joint can be exchanged for a new implant — this procedure is called a revision surgery.

Another option is to remove the implant and fuse the joint. This type of fusion is more difficult than when fusion is done as the initial procedure. When the implant is removed, there is space in the bone that must be filled with bone graft to maintain the length of the leg. Because the new bone may not be as strong, the risk of nonunion is greater.

Bunion Progression

Bunions worsen over time. As the big toe angles toward the second toe, it can cross over it and cause additional problems.

Bunions start out small — but they usually get worse over time (especially if the individual continues to wear tight, narrow shoes). Because the MTP joint flexes with every step, the bigger the bunion gets, the more painful and difficult walking can become.

An advanced bunion can greatly alter the appearance of the foot. In severe bunions, the big toe may angle all the way under or over the second toe. Pressure from the big toe may force the second toe out of alignment, causing it to come in contact with the third toe. Calluses may develop where the toes rub against each other, causing additional discomfort and difficulty walking.

Foot Problems Related to Bunions

In some cases, an enlarged MTP joint may lead to bursitis, a painful condition in which the fluid-filled sac (bursa) that cushions the bone near the joint becomes inflamed. It may also lead to chronic pain and arthritis if the smooth articular cartilage that covers the joint becomes damaged from the joint not gliding smoothly.

Adolescent Bunion

In addition to the common bunion, there are other types of bunions. As the name implies, bunions that occur in young people are called adolescent bunions. These bunions are most common in girls between the ages of 10 and 15.

While a bunion on an adult often restricts motion in the MTP joint, a young person with a bunion can normally move the big toe up and down. An adolescent bunion may still be painful, however, and make it difficult to wear shoes.

As opposed to adult bunions — which usually are associated with long-term wear of narrow, tight shoes — adolescent bunions are often genetic and run in families.

Bunionette

A bunionette, or “tailor’s bunion,” occurs on the outside of the foot near the base of the little toe. Although it is in a different spot on the foot, a bunionette is very much like a bunion. You may develop painful bursitis and a hard corn or callus over the bump.

A bunion that forms in the main joint of the little toe is called a bunionette.

Physical Examination

Your doctor will ask you about your medical history, general health, and symptoms. He or she will perform a careful examination of your foot. Although your doctor will probably be able to diagnose your bunion based on your symptoms and on the appearance of your toe, he or she will also order an x-ray.

X-Rays

X-rays provide images of dense structures, such as bone. An x-ray will allow your doctor to check the alignment of your toes and look for damage to the MTP joint.

The alignment of your foot bones changes when you stand or sit. Your doctor will take an x-ray while you are standing in order to more clearly see the malalignment of the bones of your foot. He or she will use the x-rays to determine how severe the bunion is, and how best to correct it.

X-rays of your foot will show your doctor how far out of alignment the bones have become.

Changes in Footwear

In the vast majority of cases, bunion pain can be managed successfully by switching to shoes that fit properly and do not compress the toes. Some shoes can be modified by using a stretcher to stretch out the areas that put pressure on your toes. Your doctor can give you information about proper shoe fit and the type of shoes that would be best for you. (See below section on “Tips for Proper Shoe Fit”)

Padding

Protective “bunion-shield” pads can help cushion the painful area over the bunion. Pads can be purchased at a drugstore or pharmacy. Be sure to test the pads for a short time period first; the size of the pad may increase the pressure on the bump. This could worsen your pain rather than reduce it.

Orthotics and Other Devices

To take pressure off your bunion, your doctor may recommend that you wear over-the-counter or custom-made shoe inserts (orthotics). Toe spacers can be placed between your toes. In some cases, a splint worn at night that places your big toe in a straighter position may help relieve pain.

Icing

Applying ice several times a day for 20 minutes at a time can help reduce swelling. Do not apply ice directly on your skin.

Medications

Nonsteroidal anti-inflammatory medications such as ibuprofen and naproxen can help relieve pain and reduce swelling. Other medications can be prescribed to help pain and swelling in patients whose bunions are caused by arthritis.

Pain Beneath the Heel

If it hurts under your heel, you may have one or more conditions that inflame the tissues on the bottom of your foot:

• Stone bruise. When you step on a hard object such as a rock or stone, you can bruise the fat pad on the underside of your heel. It may or may not look discolored. The pain goes away gradually with rest.
• Plantar fasciitis (subcalcaneal pain). Doing too much running or jumping can inflame the tissue band (fascia) connecting the heel bone to the base of the toes. The pain is centered under your heel and may be mild at first but flares up when you take your first steps after resting overnight. You may need to do special exercises, take medication to reduce swelling and wear a heel pad in your shoe.
• Heel spur.When plantar fasciitis continues for a long time, a heel spur (calcium deposit) may form where the fascia tissue band connects to your heel bone. Your doctor may take an X-ray to see the bony protrusion, which can vary in size. Treatment is usually the same as for plantar fasciitis: rest until the pain subsides, do special stretching exercises and wear heel pad shoe inserts.

Pain Behind the Heel

If you have pain behind your heel, you may have inflamed the area where the Achilles tendon inserts into the heel bone (retrocalcaneal bursitis). People often get this by running too much or wearing shoes that rub or cut into the back of the heel. Pain behind the heel may build slowly over time, causing the skin to thicken, get red and swell. You might develop a bump on the back of your heel that feels tender and warm to the touch. The pain flares up when you first start an activity after resting. It often hurts too much to wear normal shoes. You may need an X-ray to see if you also have a bone spur.

Treatment includes resting from the activities that caused the problem, doing certain stretching exercises, using pain medication and wearing open back shoes.

• Your doctor may want you to use a 3/8″ or 1/2″ heel insert.
• Stretch your Achilles tendon by leaning forward against a wall with your foot flat on the floor and heel elevated with the insert.
• Use nonsteroidal anti-inflammatory medications for pain and swelling.
• Consider placing ice on the back of the heel to reduce inflammation.

Nonsurgical Treatment

Ingrown toenails should be treated as soon as they are recognized. If they are recognized early (before infection sets in), home care may prevent the need for further treatment:

• Soak the foot in warm water 3-4 times daily.
• Keep the foot dry during the rest of the day.
• Wear comfortable shoes with adequate room for the toes. Consider wearing sandals until the condition clears up.
• You may take ibuprofen or acetaminophen for pain relief.
• If there is no improvement in 2-3 days, or if the condition worsens, call your doctor.

You may need to gently lift the edge of the ingrown toenail from its embedded position and insert some cotton or waxed dental floss between the nail and your skin. Change this packing every day.

Surgical Treatment

If excessive inflammation, swelling, pain and discharge are present, the toenail is probably infected and should be treated by a physician (see left image below). You may need to take oral antibiotics and the nail may need to be partially or completely removed (see middle image below). The doctor can surgically remove a portion of the nail, a portion of the underlying nail bed, some of the adjacent soft tissues and even a part of the growth center (see right image below).

Infected nail

Partially removed

Toenail surgery

Surgery is effective in eliminating the nail edge from growing inward and cutting into the fleshy folds as the toenail grows forward. Permanent removal of the nail may be advised for children with chronic, recurrent infected ingrown toenails.

If you are in a lot of pain and/or the infection keeps coming back, your doctor may remove part of your ingrown toenail (partial nail avulsion). Your toe is injected with an anesthetic and your doctor uses scissors to cut away the ingrown part of the toenail, taking care not to disturb the nail bed. An exposed nail bed may be very painful. Removing your whole ingrown toenail (complete nail plate avulsion) increases the likelihood your toenail will come back deformed. It may take 3-4 months for your nail to regrow.

Risk Factors

In most cases, plantar fasciitis develops without a specific, identifiable reason. There are, however, many factors that can make you more prone to the condition:

• Tighter calf muscles that make it difficult to flex your foot and bring your toes up toward your shin
• Obesity
• Very high arch
• Repetitive impact activity (running/sports)
• New or increased activity

Heel Spurs

Although many people with plantar fasciitis have heel spurs, spurs are not the cause of plantar fasciitis pain. One out of 10 people has heel spurs, but only 1 out of 20 people (5%) with heel spurs has foot pain. Because the spur is not the cause of plantar fasciitis, the pain can be treated without removing the spur.

Heel spurs do not cause plantar fasciitis pain.

X-rays

X-rays provide clear images of bones. They are useful in ruling out other causes of heel pain, such as fractures or arthritis. Heel spurs can be seen on an x-ray.

Other Imaging Tests

Other imaging tests, such as magnetic resonance imaging (MRI) and ultrasound, are not routinely used to diagnose plantar fasciitis. They are rarely ordered. An MRI scan may be used if the heel pain is not relieved by initial treatment methods.

Nonsurgical Treatment

More than 90% of patients with plantar fasciitis will improve within 10 months of starting simple treatment methods.

Rest. Decreasing or even stopping the activities that make the pain worse is the first step in reducing the pain. You may need to stop athletic activities where your feet pound on hard surfaces (for example, running or step aerobics).

Ice. Rolling your foot over a cold water bottle or ice for 20 minutes is effective. This can be done 3 to 4 times a day.

Nonsteroidal anti-inflammatory medication. Drugs such as ibuprofen or naproxen reduce pain and inflammation. Using the medication for more than 1 month should be reviewed with your primary care doctor.

Exercise. Plantar fasciitis is aggravated by tight muscles in your feet and calves. Stretching your calves and plantar fascia is the most effective way to relieve the pain that comes with this condition.

• Calf stretch
  Lean forward against a wall with one knee straight and the heel on the ground. Place the other leg in front, with the knee bent. To stretch the calf muscles and the heel cord, push your hips toward the wall in a controlled fashion. Hold the position for 10 seconds and relax. Repeat this exercise 20 times for each foot. A strong pull in the calf should be felt during the stretch.
• Plantar fascia stretch
  This stretch is performed in the seated position. Cross your affected foot over the knee of your other leg. Grasp the toes of your painful foot and slowly pull them toward you in a controlled fashion. If it is difficult to reach your foot, wrap a towel around your big toe to help pull your toes toward you. Place your other hand along the plantar fascia. The fascia should feel like a tight band along the bottom of your foot when stretched. Hold the stretch for 10 seconds. Repeat it 20 times for each foot. This exercise is best done in the morning before standing or walking.

Cortisone injections. Cortisone, a type of steroid, is a powerful anti-inflammatory medication. It can be injected into the plantar fascia to reduce inflammation and pain. Your doctor may limit your injections. Multiple steroid injections can cause the plantar fascia to rupture (tear), which can lead to a flat foot and chronic pain.

Soft heel pads can provide extra support.

Supportive shoes and orthotics. Shoes with thick soles and extra cushioning can reduce pain with standing and walking. As you step and your heel strikes the ground, a significant amount of tension is placed on the fascia, which causes microtrauma (tiny tears in the tissue). A cushioned shoe or insert reduces this tension and the microtrauma that occurs with every step. Soft silicone heel pads are inexpensive and work by elevating and cushioning your heel. Pre-made or custom orthotics (shoe inserts) are also helpful.

Night splints. Most people sleep with their feet pointed down. This relaxes the plantar fascia and is one of the reasons for morning heel pain. A night splint stretches the plantar fascia while you sleep. Although it can be difficult to sleep with, a night splint is very effective and does not have to be used once the pain is gone.

Physical therapy. Your doctor may suggest that you work with a physical therapist on an exercise program that focuses on stretching your calf muscles and plantar fascia. In addition to exercises like the ones mentioned above, a physical therapy program may involve specialized ice treatments, massage, and medication to decrease inflammation around the plantar fascia.

Extracorporeal shockwave therapy (ESWT). During this procedure, high-energy shockwave impulses stimulate the healing process in damaged plantar fascia tissue. ESWT has not shown consistent results and, therefore, is not commonly performed.

ESWT is noninvasive—it does not require a surgical incision. Because of the minimal risk involved, ESWT is sometimes tried before surgery is considered.

Surgical Treatment

Surgery is considered only after 12 months of aggressive nonsurgical treatment.

Gastrocnemius recession. This is a surgical lengthening of the calf (gastrocnemius) muscles. Because tight calf muscles place increased stress on the plantar fascia, this procedure is useful for patients who still have difficulty flexing their feet, despite a year of calf stretches.

In gastrocnemius recession, one of the two muscles that make up the calf is lengthened to increase the motion of the ankle. The procedure can be performed with a traditional, open incision or with a smaller incision and an endoscope, an instrument that contains a small camera. Your doctor will discuss the procedure that best meets your needs.

Complication rates for gastrocnemius recession are low, but can include nerve damage.

Plantar fascia release. If you have a normal range of ankle motion and continued heel pain, your doctor may recommend a partial release procedure. During surgery, the plantar fascia ligament is partially cut to relieve tension in the tissue. If you have a large bone spur, it will be removed, as well. Although the surgery can be performed endoscopically, it is more difficult than with an open incision. In addition, endoscopy has a higher risk of nerve damage.

Complications. The most common complications of release surgery include incomplete relief of pain and nerve damage.

Recovery. Most patients have good results from surgery. However, because surgery can result in chronic pain and dissatisfaction, it is recommended only after all nonsurgical measures have been exhausted.

Your doctor will take a complete medical history and ask about your symptoms. During the foot and ankle examination, your doctor will check whether these signs are present.

• Swelling along the posterior tibial tendon. This swelling is from the lower leg to the inside of the foot and ankle.
• A change in the shape of the foot. The heel may be tilted outward and the arch will have collapsed.

• “Too many toes” sign. When looking at the heel from the back of the patient, usually only the fifth toe and half of the fourth toe are seen. In a flatfoot deformity, more of the little toe can be seen.

This patient is able to perform a single limb heel rise on the right leg.

• “Single limb heel rise” test. Being able to stand on one leg and come up on “tiptoes” requires a healthy posterior tibial tendon. When a patient cannot stand on one leg and raise the heel, it suggests a problem with the posterior tibial tendon.

• Limited flexibility. The doctor may try to move the foot from side to side. The treatment plan for posterior tibial tendon tears varies depending on the flexibility of the foot. If there is no motion or if it is limited, there will need to be a different treatment than with a flexible foot.
• The range of motion of the ankle is affected. Upward motion of the ankle (dorsiflexion) can be limited in flatfoot. The limited motion is tied to tightness of the calf muscles.

Imaging Tests

Other tests which may help your doctor confirm your diagnosis include:

X-rays. These imaging tests provide detailed pictures of dense structures, like bone. They are useful to detect arthritis. If surgery is needed, they help the doctor make measurements to determine what surgery would most helpful.

(Top) An x-ray of a normal foot. Note that the lines are parallel, indicating a normal arch. (Bottom) In this x-ray the lines diverge, which is consistent with flatfoot deformity.

Magnetic resonance imaging (MRI). These studies can create images of soft tissues like the tendons and muscles. An MRI may be ordered if the diagnosis is in doubt.

Computerized tomography scan (CT Scan). These scans are more detailed than x-rays. They create cross-section images of the foot and ankle. Because arthritis of the back of the foot has similar symptoms to posterior tibial tendon dysfunction, a CT scan may be ordered to look for arthritis.

Ultrasound. An ultrasound uses high-frequency sound waves that echo off the body. This creates a picture of the bone and tissue. Sometimes more information is needed to make a diagnosis. An ultrasound can be ordered to show the posterior tibial tendon.

Rest

Decreasing or even stopping activities that worsen the pain is the first step. Switching to low-impact exercise is helpful. Biking, elliptical machines, or swimming do not put a large impact load on the foot, and are generally tolerated by most patients.

Ice

Apply cold packs on the most painful area of the posterior tibial tendon for 20 minutes at a time, 3 or 4 times a day to keep down swelling. Do not apply ice directly to the skin. Placing ice over the tendon immediately after completing an exercise helps to decrease the inflammation around the tendon.

Nonsteroidal Anti-inflammatory Medication

Drugs, such as ibuprofen or naproxen, reduce pain and inflammation. Taking such medications about a half of an hour before an exercise activity helps to limit inflammation around the tendon. The thickening of the tendon that is present is degenerated tendon. It will not go away with medication. Talk with your primary care doctor if the medication is used for more than 1 month.

Immobilization

A short leg cast or walking boot may be used for 6 to 8 weeks. This allows the tendon to rest and the swelling to go down. However, a cast causes the other muscles of the leg to atrophy (decrease in strength) and thus is only used if no other conservative treatment works.

Orthotics

Most people can be helped with orthotics and braces. An orthotic is a shoe insert. It is the most common nonsurgical treatment for a flatfoot. An over-the-counter orthotic may be enough for patients with a mild change in the shape of the foot. A custom orthotic is required in patients who have moderate to severe changes in the shape of the foot. The custom orthotic is more costly, but it allows the doctor to better control the position the foot.

Braces

A lace-up ankle brace may help mild to moderate flatfoot. The brace would support the joints of the back of the foot and take tension off of the tendon. A custom-molded leather brace is needed in severe flatfoot that is stiff or arthritic. The brace can help some patients avoid surgery.

Physical Therapy

Physical therapy that strengthens the tendon can help patients with mild to moderate disease of the posterior tibial tendon.

Steroid Injection

Cortisone is a very powerful anti-inflammatory medicine that your doctor may consider injecting around the tendon. A cortisone injection into the posterior tibial tendon is not normally done. It carries a risk of tendon rupture. Discuss this risk with your doctor before getting an injection.

Gastrocnemius Recession or Lengthening of the Achilles Tendon

This is a surgical lengthening of the calf muscles. It is useful in patients who have limited ability to move the ankle up. This surgery can help prevent flatfoot from returning, but does create some weakness with pushing off and climbing stairs. Complication rates are low but can include nerve damage and weakness. This surgery is typically performed together with other techniques for treating flatfoot.

Tenosynovectomy (Cleaning the Tendon)

This surgery is used when there is very mild disease, the shape of the foot has not changed, and there is pain and swelling over the tendon. The surgeon will clean away and remove the inflamed tissue (synovium) surrounding the tendon. This can be performed alone or in addition to other procedures. The main risk of this surgery is that the tendon may continue to degenerate and the pain may return.

Tendon Transfer

Tendon transfer can be done in flexible flatfoot to recreate the function of the damaged posterior tibial tendon. In this procedure, the diseased posterior tibial tendon is removed and replaced with another tendon from the foot, or, if the disease is not too significant in the posterior tibial tendon, the transferred tendon is attached to the preserved (not removed) posterior tibial tendon.

One of two possible tendons are commonly used to replace the posterior tibial tendon. One tendon helps the big toe point down and the other one helps the little toes move down. After the transfer, the toes will still be able to move and most patients will not notice a change in how they walk.

Although the transferred tendon can substitute for the posterior tibial tendon, the foot still is not normal. Some people may not be able to run or return to competitive sports after surgery. Patients who need tendon transfer surgery are typically not able to participate in many sports activities before surgery because of pain and tendon disease.

Osteotomy (Cutting and Shifting Bones)

An osteotomy can change the shape of a flexible flatfoot to recreate a more “normal” arch shape. One or two bone cuts may be required, typically of the heel bone (calcaneus).

If flatfoot is severe, a bone graft may be needed. The bone graft will lengthen the outside of the foot. Other bones in the middle of the foot also may be involved. They may be cut or fused to help support the arch and prevent the flatfoot from returning. Screws or plates hold the bones in places while they heal.

X-ray of a foot as viewed from the side in a patient with a more severe deformity. This patient required fusion of the middle of the foot in addition to a tendon transfer and cut in the heel bone.

Fusion

Sometimes flatfoot is stiff or there is also arthritis in the back of the foot. In these cases, the foot will not be flexible enough to be treated successfully with bone cuts and tendon transfers. Fusion (arthrodesis) of a joint or joints in the back of the foot is used to realign the foot and make it more “normal” shaped and remove any arthritis. Fusion involves removing any remaining cartilage in the joint. Over time, this lets the body “glue” the joints together so that they become one large bone without a joint, which eliminates joint pain. Screws or plates hold the bones in places while they heal.

This x-ray shows a very stiff flatfoot deformity. A fusion of the three joints in the back of the foot is required and can successfully recreate the arch and allow restoration of function.

Side-to-side motion is lost after this operation. Patients who typically need this surgery do not have a lot of motion and will see an improvement in the way they walk. The pain they may experience on the outside of the ankle joint will be gone due to permanent realignment of the foot. The up and down motion of the ankle is not greatly affected. With any fusion, the body may fail to “glue” the bones together. This may require another operation.

Complications

The most common complication is that pain is not completely relieved. Nonunion (failure of the body to “glue” the bones together) can be a complication with both osteotomies and fusions. Wound infection is a possible complication, as well.

Surgical Outcome

Most patients have good results from surgery. The main factors that determine surgical outcome are the amount of motion possible before surgery and the severity of the flatfoot. The more severe the problem, the longer the recovery time and the less likely a patient will be able to return to sports. In many patients, it may be 12 months before there is any great improvement in pain.

How It Happens

The joints of your body are covered with a lining — called synovium — that lubricates the joint and makes it easier to move. Rheumatoid arthritis causes an overactivity of this lining. It swells and becomes inflamed, destroying the joint, as well as the ligaments and other tissues that support it. Weakened ligaments can cause joint deformities — such as claw toe or hammer toe. Softening of the bone (osteopenia) can result in stress fractures and collapse of bone.

Rheumatoid arthritis is not an isolated disease of the bones and joints. It affects tissues throughout the body, causing damage to the blood vessels, nerves, and tendons. Deformities of the hands and feet are the more obvious signs of RA. In about 20% of patients, foot and ankle symptoms are the first signs of the disease.

In RA, the lining of the joint swells and becomes inflamed. This slowly destroys the joint.

Statistics

Rheumatoid arthritis affects approximately 1% of the population. Women are affected more often than men, with a ratio of up to 3 to 1. Symptoms most commonly develop between the ages of 40 and 60.

Ankle

Difficulty with inclines (ramps) and stairs are the early signs of ankle involvement. As the disease progresses, simple walking and standing can become painful.

Hindfoot (Heel Region of the Foot)

The main function of the hindfoot is to perform the side-to-side motion of the foot. Difficulty walking on uneven ground, grass, or gravel are the initial signs. Pain is common just beneath the fibula (the smaller lower leg bone) on the outside of the foot.

As the disease progresses, the alignment of the foot may shift as the bones move out of their normal positions. This can result in a flatfoot deformity. Pain and discomfort may be felt along the posterior tibial tendon (main tendon that supports the arch) on the inside of the ankle, or on the outside of the ankle beneath the fibula.

Midfoot (Top of the Foot)

With RA, the ligaments that support the midfoot become weakened and the arch collapses. With loss of the arch, the foot commonly collapses and the front of the foot points outward. RA also damages the cartilage, causing arthritic pain that is present with or without shoes. Over time, the shape of the foot can change because the structures that support it degenerate. This can create a large bony prominence (bump) on the arch. All of these changes in the shape of the foot can make it very difficult to wear shoes.

This x-ray shows signs of RA of the midfoot. Note that the front of the foot points outward and there is a large bump on the inside and bottom of the foot.

Forefoot (Toes and Ball of the Foot)

The changes that occur to the front of the foot are unique to patients with RA. These problems include bunions, claw toes, and pain under the ball of the foot (metatarsalgia). Although, each individual deformity is common, it is the combination of deformities that compounds the problem.

People with RA can experience a combination of common foot problems, such as bunions and clawtoe.

The bunion is typically severe and the big toe commonly crosses over the second toe.

There can also be very painful bumps on the ball of the foot, creating calluses. The bumps develop when bones in the middle of the foot (midfoot) are pushed down from joint dislocations in the toes. The dislocations of the lesser toes (toes two through five) cause them to become very prominent on the top of the foot. This creates clawtoes and makes it very difficult to wear shoes. In severe situations, ulcers can form from the abnormal pressure.

Severe claw toes can become fixed and rigid. They do not move when in a shoe. The extra pressure from the top of the shoe can cause severe pain and can damage the skin.

Medical History and Physical Examination

After listening to your symptoms and discussing your general health and medical history, your doctor will examine your foot and ankle.

Skin. The location of callouses indicate areas of abnormal pressure on the foot. The most common location is on the ball of the foot (the underside of the forefoot). If the middle of the foot is involved, there may be a large prominence on the inside and bottom of the foot. This can cause callouses.

Foot shape. Your doctor will look for specific deformities, such as bunions, claw toes, and flat feet.

Flexibility. In the early stages of RA, the joints will typically still have movement. As arthritis progresses and there is a total loss of cartilage, the joints become very stiff. Whether there is motion within the joints will influence treatment options.

Tenderness to pressure. Although applying pressure to an already sensitive foot can be very uncomfortable, it is critical that your doctor identify the areas of the foot and ankle that are causing the pain. By applying gentle pressure at specific joints your doctor can determine which joints have symptoms and need treatment. The areas on the x-ray that look abnormal are not always the same ones that are causing the pain.

Imaging Tests

Other tests that your doctor may order to help confirm your diagnosis include:

X-rays. This test creates images of dense structures, like bone. It will show your doctor the position of the bones. The x-rays can be used by your doctor to make measurements of the alignment of the bones and joint spaces, which will help your doctor determine what surgery would best.

Computerized tomography (CT) scan. When the deformity is severe, the shape of the foot can be abnormal enough to make it difficult to determine which joints have been affected and the extent of the disease. CT scans allow your doctor to more closely examine each joint for the presence of arthritis.

Magnetic resonance imaging (MRI) scan. An MRI scan will show the soft tissues, including the ligaments and tendons. Your doctor can assess whether the tendon is inflamed (tendonitis) or torn (ruptured).

Rheumatology Referral

Your doctor may refer you to a rheumatologist if he or she suspects RA. Although your symptoms and the results from a physical examination and tests may be consistent with RA, a rheumatologist will be able to determine the specific diagnosis. There are other less common types of inflammatory arthritis that will be considered.

Rest

Limiting or stopping activities that make the pain worse is the first step in minimizing the pain. Biking, elliptical training machines, or swimming are exercise activities that allow patients to maintain their health without placing a large impact load on the foot.

Ice

Placing ice on the most painful area of the foot for 20 minutes is effective. This can be done 3 or 4 times a day. Ice application is best done right after you are done with a physical activity. Do not apply ice directly to your skin.

Nonsteroidal Anti-inflammatory Medication

Drugs, such as ibuprofen or naproxen, reduce pain and inflammation. In patients with RA, the use of these types of medications should be reviewed with your rheumatologist or medical doctor.

Orthotics

An orthotic (shoe insert) is a very effective tool to minimize the pressure from prominent bones in the foot. The orthotic will not be able to correct the shape of your foot. The primary goal is to minimize the pressure and decrease the pain and callous formation. This is more effective for deformity in the front and middle of the foot.

A custom-molded leather brace can be effective in minimizing the pain and discomfort from ankle and hindfoot arthritis.

For people with RA, hard or rigid orthotics generally cause too much pressure on the bone prominences, creating more pain. A custom orthotic is generally made of softer material and relieves pressure on the foot.

Braces

A lace-up ankle brace can be an effective treatment for mild to moderate pain in the back of the foot and the ankle. The brace supports the joints of the back of the foot and ankle. In patients with a severe flatfoot or a very stiff arthritic ankle, a custom-molded plastic or leather brace is needed. The brace can be a very effective device for some patients, allowing them to avoid surgery.

Steroid Injection

An injection of cortisone into the affected joint can help in the early stages of the disease. In many cases, a rheumatologist or medical doctor may also perform these injections. The steroid helps to reduce inflammation within the joint. The steroid injection is normally a temporary measure and will not stop the progression of the disease.

Ankle

Ankle fusion and total ankle replacement are the two primary surgical options for treating RA of the ankle. Both treatment options can be successful in minimizing the pain and discomfort in the ankle. The appropriate surgery is based upon multiple factors and is individualized for every patient.

The patient shown in these x-rays had arthritis of the hindfoot. It was treated by fusing all three joints of the hindfoot (triple fusion). An ankle replacement was also done in order to improve mobility and avoid the severe stiffness that would result from another ankle fusion. The ankle replacement implants can be seen here from the front and the side.

Patients with severe involvement of other joints around the heel or patients who have previously undergone a fusion on the other leg, may be more suited for ankle replacement. In addition, patients who have fusions within the same foot may be more suited for an ankle replacement.

Newer generation ankle replacement implants have shown promising early results. Ankle replacement implants have not yet been shown to be as long-lasting as those for the hip or knee, due to the fact that the newer generation of implants have not been available long enough to determine how long they will last.

These x-rays show an ankle fusion from the front and the side. The number and placement of screws and the use of a plate are dependent upon the surgeon’s technique.

Following ankle fusion, there is a loss of the up and down motion of the ankle. The up and down motion is transferred to the joints near the ankle. This creates a potential for pain in those joints, and possibly arthritis.

Patients are able to walk in shoes on flat, level ground without much difficulty after an ankle fusion, despite the loss of ankle motion. The joints in the foot next to the ankle joint allow for motion similar to the ankle joint, and help patients with fused ankle joints walk more normally.

Over time, the increased stress that is placed on the rest of the foot after an ankle fusion can lead to arthritis of the joints surrounding the ankle. This patient had pain in the subtalar joint (arrow) and required an additional fusion of that joint to minimize the pain. Increased stress on other joints is the most concerning problem following ankle fusion.

Hindfoot (Heel Region of the Foot)

A fusion of the affected joints of the hindfoot is the most common surgery used to treat patients with flatfoot or arthritis of the hindfoot. A triple arthrodesis is a fusion that involves all three joints in the back of the foot. Occasionally, the joint on the outside of the foot is not fused if there is minimal to no involvement of that joint (this is at the surgeon’s discretion). This type of fusion eliminates the side-to-side motion of the foot, while preserving most of the up and down movement.

If RA is only in one joint, then a fusion of just that affected joint may be all that is needed.

(Left) In this x-ray, two of the three joints in the hindfoot have been fused. (Right) Just the subtalar joint is fused in this x-ray.

Any fusion of the hindfoot will limit side-to-side motion of the foot. This will affect walking on uneven ground, grass, or gravel. There is no method to replace the joints of the hindfoot.

Midfoot (Middle of the Foot)

Fusion is the most reliable surgical method to treat RA of the midfoot joints. If the shape of the foot is not normal, surgery is designed to help restore the arch and minimize the prominences on the foot.

There are joint replacement implants available for joints on the outside of the midfoot. This may preserve some midfoot motion. However, the use of these implants is at the surgeon’s discretion. These implants are not available for the joints on the inside of the midfoot.

Although the foot cannot be returned to a normal shape, the goals are to reduce pain in the foot and improve the potential for the patient to wear more normal shoes.

(Top) This x-ray shows RA of the midfoot that has collapsed the arch. (Bottom) The surgical reconstruction involved a fusion of the middle of the foot with plates and screws.

Forefoot (Toes and Ball of the Foot)

The choice of treatment for patients with a bunion or lesser toe deformities (hammer or claw toes) depends on a number of factors.

If the disease is very mild, joint-sparing procedures that preserve motion can be considered. The decision is dependent on the medication that the patient is taking and the amount of damaged cartilage that is present. A fusion of the great toe may be recommended despite that fact the bunion is very mild. If there is damage to the cartilage of the great toe joint, correcting the bunion will not minimize the arthritic pain.

If the RA has progressed and the lesser toes (two through five) have dislocated, a complex operation to minimize the pain and restore the shape of the foot may be recommended. The operation involves fusion of the big toe and removing a portion of bone of each of the metatarsals. This surgery removes the prominent bone on the bottom of the foot that is a source of the pain and allows the toes to re-align into a better position.

Occasionally, the lesser toe metatarsals can be preserved by shortening them to allow the toes to resume their position within the joints. This is not always possible, however, and the joint may have to be removed.

(Left) RA of the forefoot. The big toe is deviated and crosses over the second toe, a typical appearance of a bunion. The lesser toes (two through five) are dislocated, resulting in painful and severe claw toes. (Right) This x-ray taken immediately after fusion of the big toe shows that the prominent bones on the ball of the foot were removed and the claw toes were corrected. The pins hold the toes in place while the soft tissues heal. The pins are removed in the office after 4 to 6 weeks with minimal discomfort.

To fix the bend in the toes themselves, the surgeon may suggest cutting a tendon or removing a small portion of bone of the toes to allow them to straighten. Pins that stick out of the foot are temporarily required and will be removed in the office after healing takes place.

There are some newer implants available that can be buried within the toes, which avoid the need for pins sticking out of the foot. These implants may not work if the bone is soft, or if significant destruction of the joints has occurred.

This operation puts a lot of stress on the blood vessels and skin of the foot. In severe cases, the toes may not survive the operation and may require amputation of a portion or the entire toe. This operation can provide the patient with a high level of function and the ability to enjoy a wider variety of shoewear.

Preparing for Surgery

Many of the medications that help with RA also affect the ability of the body to heal wounds and fight infection. Your surgeon will work with your rheumatologist or medical doctor to review which of your medications will need to be stopped prior to surgery. Once the wounds are healed, the medication is typically resumed.

This period of time can be very difficult for patients with other areas of the body that are affected by RA. Many fusions require at least 6 weeks of time where no pressure can be placed on the foot. Making appropriate preparations to ensure you have help at home is crucial for success after surgery.

Nonsurgical Treatment

Pain relievers and anti-inflammatory medications such as ibuprofen may help reduce the swelling and ease the pain. Applying ice packs or taking contrast baths (described below) may also help reduce inflammation and control symptoms for a short period of time. But they aren’t enough to stop the condition from progressing. Wearing a shoe with a large toe box will reduce the pressure on the toe, and you will probably have to give up wearing high heels. Your doctor may recommend that you get a stiff-soled shoe with a rocker or roller bottom design and possibly even a steel shank or metal brace in the sole. This type of shoe supports the foot when you walk and reduces the amount of bend in the big toe.

A contrast bath uses alternating cold and hot water to reduce inflammation. You’ll need two buckets, one with water as cold as you can tolerate and the other with water as warm as you can tolerate. Immerse your foot in the cold water for 30 seconds, then immediately place it in the hot water for 30 seconds. Continue to alternate between cold and hot for five minutes, ending in the cold water. You can do contrast baths up to three times a day. However, be careful to avoid extreme temperatures in the water, especially if your feet aren’t very sensitive to heat or cold.

Surgical Treatment

• Cheilectomy (kI-lek’-toe-me)This surgery is usually recommended when damage is mild or moderate. It involves removing the bone spurs as well as a portion of the foot bone, so the toe has more room to bend. The incision is made on the top of the foot. The toe and the operative site may remain swollen for several months after the operation, and you will have to wear a wooden-soled sandal for at least two weeks after the surgery. But most patients do experience long-term relief.
• Arthrodesis (are-throw-dee’-sis)Fusing the bones together (arthrodesis) is often recommended when the damage to the cartilage is severe. The damaged cartilage is removed and pins, screws, or a plate are used to fix the joint in a permanent position. Gradually, the bones grow together. This type of surgery means that you will not be able to bend the toe at all. However, it is the most reliable way to reduce pain in these severe cases.For the first six weeks after surgery, you will have to wear a cast and then use crutches for about another six weeks. You won’t be able to wear high heels, and you may need to wear a shoe with a rocker-type sole.
• Arthroplasty (are-throw-plas’-tee)Older patients who place few functional demands on the feet may be candidates for joint replacement surgery. The joint surfaces are removed and an artificial joint is implanted. This procedure may relieve pain and preserve joint motion.

Medical History and Physical Examination

After discussing your symptoms and general health history, your doctor will do a complete examination of your foot and ankle, which will include checking your foot flexibility and gait. Patients with tarsal coalitions may have a flat arch that does not fully correct when pushing up on the toes and raising the heel.

(Left) A side view of a young person with flat foot. (Right) The feet remain flat when performing a toe raise.

Imaging Tests

To accurately diagnose the number, location and extent of the coalition(s), your doctor will order images of your foot and ankle.

• X-rays. These tests provide clear images of bone. Many coalitions are visible on x-rays.
• Computed tomography (CT) scans. The images produced with computed tomography provide greater detail of the bones. CT scans are the gold standard for imaging tarsal coalitions because they can show more subtle bars that may be missed with plain x-rays.

This CT image displays a cross-section view of the hindfoot and shows a large coalition fusing the talus and calcaneus bones.

Magnetic resonance (MRI) scans. These imaging tests provide detailed pictures that include soft tissues. Your doctor may order this test to look for irregular bars formed from cartilage or fibrous tissue.

Nonsurgical Treatment

• Rest. Taking a break from high-impact activity for a period time — 3 to 6 weeks — can reduce stress on the tarsal bones and relieve pain.
• Orthotics. Arch supports, shoe inserts like heel cups and wedges, and other types of orthotics may be recommended to help stabilize the foot and relieve pain.
• Temporary boot or cast. These options can immobilize the foot and take stress off of the tarsal bones.
• Injections. Steroid medications may be used in conjunction with other nonsurgical options to provide temporary pain relief.

Surgical Treatment

When nonsurgical treatments are not effective at easing pain or improving function, your doctor may consider surgery.

The surgical procedure your doctor recommends will depend on the size and location of the coalition, as well as whether the joints between the bones show signs of arthritis.

• Resection. In this procedure, the coalition is removed and replaced with muscle or fatty tissue from another area of the body. This is the most common surgery for tarsal coalition because it preserves normal foot motion and successfully relieves symptoms in most patients who do not have signs of arthritis.

These CT cross-section images show a patient with coalitions between the calcaneus and talus in both feet. At the time of this scan, the coalition on the left foot had been resected, and the right foot was awaiting the procedure.

• Fusion. Larger, more severe coalitions that cause significant deformity and also involve arthritis may be treated with joint fusion. The goal of fusion is to limit movement of painful joints and place the bones in the proper position. In fusion for tarsal coalition, the bones may be held in place with large screws, pins, or screw-and-plate devices.

Repairing the Tendons and Ligaments Around the Big Toe

In some cases, the soft tissues around the big toe may be too tight on one side and too loose on the other. This creates an imbalance that causes the big toe to drift toward the other toes.

Surgery can shorten the loose tissues and lengthen the tight ones. This is rarely done without some type of alignment of the bone, called an osteotomy. In the majority of cases, soft tissue correction is just one portion of the entire bunion corrective procedure.

Osteotomy

In an osteotomy, your doctor makes small cuts in the bones to realign the joint. After cutting the bone, your doctor fixes this new break with pins, screws, or plates. The bones are now straighter, and the joint is balanced.

Osteotomies may be performed in different places along the bone to correct the deformity. In some cases, in addition to cutting the bone, a small wedge of bone is removed to provide enough correction to straighten the toe.

As discussed above, osteotomies are normally performed in combination with soft tissue procedures, as both are often necessary to maintain the big toe alignment.

X-rays taken from the top and the side of the foot show a bunion corrected with osteotomy.

Arthrodesis

In this procedure, your doctor removes the arthritic joint surfaces, then inserts screws, wires, or plates to hold the surfaces together until the bones heal. Arthrodesis is commonly used for patients who have severe bunions or severe arthritis, and for patients who have had previous unsuccessful bunion surgery.

The x-ray on the left shows severe arthritis of the MTP joint. After arthrodesis (shown on the right), the entire foot is realigned. An advantage of arthrodesis is that no additional procedures are necessary to correct the bunion.

Exostectomy

In this procedure, your doctor removes the bump from your toe joint. Exostectomy alone is seldom used to treat bunions because it does not realign the joint. Even when combined with soft tissue procedures, exostectomy rarely corrects the cause of the bunion.

Exostectomy is most often performed as one part of an entire corrective surgery that includes osteotomy, as well as soft-tissue procedures. If a doctor performs exostectomy without osteotomy, however, the bunion deformity often returns.

The x-ray on the left shows a mild bunion bump before exostectomy. After the procedure (right), the bump has been shaved but the toe deformity remains and is actually worse; the big toe drifts closer to the other toes and the metatarsal bone sticks out further.

Resection Arthroplasty

In this procedure, your doctor removes the damaged portion of the joint. This increases the space between the bones and creates a flexible “scar” joint. Resection arthroplasty is used mainly for patients who are elderly, have had previous unsuccessful bunion surgery, or have severe arthritis not amenable to an arthrodesis (see above). Because this procedure can change the push off power of the big toe, it is not often recommended.

This x-ray shows a failed resection arthroplasty. Although the damaged bone of the MTP joint was removed, scar tissue did not fill the space between the bones. The bone edges are still in contact. The photograph shows that without the needed scar tissue, the big toe is shortened. This makes it more difficult to push off while walking.

Medical Evaluation

Before your surgery, you may be asked to visit your family doctor for a complete physical examination. He or she will assess your health and identify any problems that could interfere with your surgery. If you have a heart or lung condition or a chronic illness you will need a preoperative medical clearance from your family doctor.

Medications

Tell your doctor about any medications you are taking. He or she will tell you which medications you can continue taking and which you should stop taking before surgery.

Tests

You may require several preoperative tests, including blood counts, a cardiogram, and a chest x-ray. You may also need to provide a urine sample.

To help plan your procedure, your doctor may order special foot x-rays. These x-rays should be taken in a standing, weight bearing position to ensure your doctor can clearly see the deformity in the foot. These x-rays assist your doctor in making decisions about where along the bone to perform an osteotomy in order to provide enough corrective power to straighten the toe.

Anesthesia

After admission, you will be evaluated by a member of the anesthesia team. Most bunion surgery is performed with anesthesia that numbs the area for surgery but does not put you to sleep.

• Local anesthesia. An ankle block numbs just your foot.
• Regional anesthesia. A popliteal block works for a longer period of time compared to an ankle block and numbs more of the leg. The numbing medicine is injected behind the knee.
• Spinal anesthesia. This injection will numb your body below your waist.
• General anesthesia. This form of anesthesia will put you to sleep.

The anesthesiologist will stay with you throughout the procedure to administer other medications, if necessary, and to make sure you are comfortable.

Procedure

Depending upon your bunion and the procedures you need, your doctor will make an incision along the inside of your big toe joint or on top of the joint. In some cases, more than one incision is needed to correct the bunion deformity.

The surgical time varies depending on how much of your foot is malaligned. Surgery will take longer if your deformity is greater or if more than one osteotomy is required. Every bunion correction is a little bit different, and there is no reason to be concerned if your surgery takes more time.

Afterward, you will be moved to the recovery room. You will be ready to go home in an hour or two. Be sure to have someone with you to drive you home.

Complications

As with any surgical procedure, there are risks associated with bunion surgery. These occur infrequently and are usually treatable — although, in some cases, they may limit or extend your full recovery. Before your surgery, your doctor will discuss each of the risks with you and take specific measures to avoid complications.

The possible risks and complications of bunion surgery include:

• Infection
• Nerve injury
• Failure to relieve pain
• Failure of the bone to fully heal
• Stiffness of the big toe joint
• Recurrence of the bunion

You will be discharged from the hospital with bandages holding your toe in its corrected position.

Because keeping your toe in position is essential for successful healing, it is very important to follow your doctor’s directions about dressing care. Do not disturb or change the dressing without talking to your doctor. Interfering with proper healing could cause a recurrence of the bunion.

Be sure to keep your wound and dressing dry. When you are showering or bathing, cover your foot with a plastic bag.

Your sutures will be removed about 2 weeks after surgery, but your foot will require continued support from dressings or a brace for 6 to 12 weeks.

Swelling

Keep your foot elevated as much as possible for the first few days after surgery, and apply ice as recommended by your doctor to relieve swelling and pain. Never apply ice directly on your skin. It is common to have some swelling in your foot from 6 months to a year after bunion surgery.

Bearing Weight

Your doctor will give you strict instructions about whether and when you can put weight on your foot. Depending upon the type of procedure you have, if you put weight on your foot too early or without proper support, the bones can shift and the bunion correction will be lost.

Some bunion procedures allow you to walk on your foot right after the surgery. In these cases, patients must use a special surgical shoe to protect the bunion correction.

Many bunion surgeries require a period of no weightbearing to ensure bone healing. Your doctor will apply dressings, a brace, or a cast to maintain the correct bone position. Crutches are usually used to avoid putting any weight on the foot. A newer device called a knee walker is a good alternative to crutches. It has four wheels and functions like a scooter. Instead of standing, you place the knee of your affected foot on a padded cushion and push yourself along using your healthy foot.

In addition to no weightbearing, driving may be restricted until the bones have healed properly — particularly if the surgery was performed on your right foot.

No matter what type of bunion surgery you have, it is very important to follow your doctor’s instructions about weightbearing. Do not put weight on your foot or stop using supportive devices until your doctor gives approval.

Physical Therapy and Exercise

Specific exercises will help restore your foot’s strength and range of motion after surgery. Your doctor or physical therapist may recommend exercises using a surgical band to strengthen your ankle or using marbles to restore motion in your toes.

Always start these exercises slowly and follow instructions from your doctor or physical therapist regarding repetitions.

Shoe Wear

It will take several months for your bones to fully heal. When you have completed the initial rehabilitation period, your doctor will advise you on shoewear. Athletic shoes or soft leather oxford type shoes will best protect the bunion correction until the bones have completely healed.

To help prevent your bunion from recurring, do not wear fashion shoes until your doctor allows it. Be aware that your doctor may recommend that you never return to wearing high-heeled shoes.

Avoiding Complications

Though uncommon, complications can occur following bunion surgery. During your recovery at home, contact your doctor if:

• Your dressing loosens, comes off, or gets wet.
• Your dressing is moistened with blood or drainage.
• You develop side effects from postoperative medications.

Also, call your doctor immediately if you notice any of the following warning signs of infection:

• Persistent fever
• Shaking chills
• Persistent warmth or redness around the dressing
• Increased or persistent pain, especially a “sunburn” type pain
• Significant swelling in the calf above the treated foot, especially if there is a “charley horse” pain behind the knee, or if your develop shortness of breath.
