Overview
What are hammertoes, mallet toes and claw toes? Often the words are used interchangeably to mean an abnormally contracted toe like the drawing above. Technically speaking, a "Hammertoe" is the name for a toe that is contracted at the first toe joint. If it's contracted at the second toe joint it is called a "mallet toe". IIf a toe is contracted at both toe joints, it is called a "claw toe". Each of these conditions can be quite uncomfortable and are cosmetically unappealing.

Causes
But what causes the imbalance of the tendons and muscles in the first place so that they begin to pull and bend the joint? A bad fitting shoe could be the cause but it usually isn?t the primary cause. Many people are genetically predisposed to hammertoe, and the condition begins to progress more quickly when they wear shoes that fit poorly, for example pointy toes, high heels, or shoes that are too short. Hammertoe may also be caused by damage to the joint as a result of trauma.

Symptoms
Hammer toe is often distinguished by a toe stuck in an upside-down ?V? position, and common symptoms include corns on the top of your toe joint. Pain at the top of a bent toe when you put on your shoes. Pain when moving a toe joint. Pain on the ball of your foot under the bent toe. Corns developing on the top of the toe joint. It is advisable to seek medical advice if your feet hurt on a regular basis. It is imperative to act fast and seek the care of a podiatrist or foot surgeon. By acting quickly, you can prevent your problem from getting worse.

Diagnosis
Hammertoes are progressive, they don?t go away by themselves and usually they will get worse over time. However, not all cases are alike, some hammertoes progress more rapidly than others. Once your foot and ankle surgeon has evaluated your hammertoes, a treatment plan can be developed that is suited to your needs.

Non Surgical Treatment
Symptomatic treatment of hammertoes consists of such things as open toed shoes or hammertoe pads. There are over the counter corn removers for temporally reducing the painful callous often seen with the hammertoe. These medications must be used with caution. They are a mild acid that burns the callous off. These medications should never be used for corns or callouses between the toes. Persons with diabetes or bad circulation should never use these products.

Surgical Treatment
Surgical Options: Several surgical procedures are available to the podiatric physician. For less severe deformities, the surgery will remove the bony prominence and restore normal alignment of the toe joint, thus relieving pain. Severe hammer toes, which are not fully reducible, may require more complex surgical procedures. Recuperation takes time, and some swelling and discomfort are common for several weeks following surgery. Any pain, however, is easily managed with medications prescribed by your podiatrist.

Prevention
In some cases foot problems may present at birth, many foot problems such as hammer toes can be prevented. Hammer toe prevention can be a simple process, such as, checking your feet regularly and wearing the right shoes for your feet. Good circulation is also an essential part of foot health and hammer toe prevention. Taking a warm foot bath or giving yourself a foot massage are great ways of keeping your feet healthy.

Overview
Hammer toes are usually not a serious condition, but can become painful as the bent joint rubs against the inside of the shoe, causing irritation, corns, or calluses on the top of the middle joint or the tip of the toe. A Hammer Toe may also cause occasional shooting pains throughout the toes or elsewhere in the foot. A hammertoe has a kink or contracture in its second joint--called the proximal interphalangeal joint--that causes the toe to bend upward in the middle, giving it a hammer-like appearance. The raised part of the toe often rubs on shoes, leading to the formation of corns or calluses. Usually hammertoe affects the smaller toes, causing pain and interfering with the ability to walk normally.

Causes
Hammer toe is most often caused by wearing compressive shoes. It might also be caused by the pressure from a bunion. A bunion is a corn on the top of a toe and a callus on the sole of the foot develop which makes walking painful. A high foot arch may also develop.

Symptoms
The symptoms of hammertoe are progressive, meaning that they get worse over time. Hammertoe causes the middle joint on the second, third, fourth, or fifth toes to bend. The affected toe may be painful or irritated, especially when you wear shoes. Areas of thickened skin (corns) may develop between, on top of, or at the end of your toes. Thickened skin (calluses) may also appear on the bottom of your toe or the ball of your foot. It may be difficult to find a pair of shoes that is comfortable to wear.

Diagnosis
Hammertoes are progressive, they don?t go away by themselves and usually they will get worse over time. However, not all cases are alike, some hammertoes progress more rapidly than others. Once your foot and ankle surgeon has evaluated your hammertoes, a treatment plan can be developed that is suited to your needs.

Non Surgical Treatment
Often padding and taping are the first steps in a treatment plan. Padding the hammer toe prominence minimizes pain and allows the patient to continue a normal, active life. Taping may change the imbalance around the toes and thus relieve the stress and pain. Anti-inflammatory drugs and cortisone injections can be prescribed to ease acute pain and inflammation caused by the joint deformity. Custom shoe inserts made by your podiatrist may be useful in controlling foot function. An orthotic device may reduce symptoms and prevent the worsening of the hammer toe deformity.

Surgical Treatment
For severe hammer toe, you will need an operation to straighten the joint. The surgery often involves cutting or moving tendons and ligaments. Sometimes the bones on each side of the joint need to be connected (fused) together. Most of the time, you will go home on the same day as the surgery. The toe may still be stiff afterward, and it may be shorter. If the condition is treated early, you can often avoid surgery. Treatment will reduce pain and walking difficulty.

Overview

A bunion is a bone deformity caused by an enlargement of the joint at the base and side of the big toe ( metatarsophalangeal joint ). Bunions form when the toe moves out of place. The enlargement and its protuberance cause friction and pressure as they rub against footwear. The growing enlargement or protuberance then causes more irritation or inflammation. In some cases, the big toe moves toward the second toe and rotates or twists, which is known as Hallux Abducto Valgus. Bunions can also lead to other toe deformities, such as hammertoe.

Causes
Bunions, Corns, and Calluses are all related in that they can each be caused by tight and/or poor fitting footwear. Each can also be caused by the following, footwear that is too narrow and/or too small. Constrictive toe boxes (toe area). Tapered toe boxes can cause bunions and cause them to worsen to the point of needing surgery.
SymptomsIf you have a bunion, you may have pain or stiffness of your big toe joint, swelling of your big toe joint, difficulty walking, difficulty finding shoes that fit. These symptoms may be caused by conditions other than bunions, but if you have any of these symptoms, see your doctor.

Diagnosis
A thorough medical history and physical exam by a physician is necessary for the proper diagnosis of bunions and other foot conditions. X-rays can help confirm the diagnosis by showing the bone displacement, joint swelling, and, in some cases, the overgrowth of bone that characterizes bunions. Doctors also will consider the possibility that the joint pain is caused by or complicated by Arthritis, which causes destruction of the cartilage of the joint. Gout, which causes the accumulation of uric acid crystals in the joint. Tiny fractures of a bone in the foot or stress fractures. Infection. Your doctor may order additional tests to rule out these possibilities.

Non Surgical Treatment
You can buy orthotics over the counter from pharmacies, or they can be custom-made by a podiatrist to fit your feet. Whether you need to buy an over-the-counter orthotic or have one specially made will depend on your individual circumstances and the severity of your bunion. You can also use special bunion splints, worn over the top of your foot and your big toe to help straighten its alignment. Splints are available for both daytime and night-time use. However, there's little evidence that splints are effective. Toe spacers are also available, which can help reduce the pain caused by bunions. However, toe spacers or orthotics may be of limited use because they often compete with the bunion for the already limited space in the shoe. If your toe joint is painful and swollen, applying an ice pack to the affected area several times a day can help to relieve the pain and inflammation. Never apply ice directly to your skin. Wrap it in a cloth or tea towel. A bag of frozen vegetables makes a good ice pack. It's recommended that you wear flat or low-heeled, wide-fitting shoes if you have a bunion. Shoes made from soft leather are ideal because they'll relieve any pressure on the bunion. Avoid narrow or slip-on shoes. High heels can also make your bunion worse by putting excessive pressure on your toes.


Surgical Treatment
Surgery is a last option for those with advanced and painful bunions that do not respond to any other treatment. The surgical operation to correct the deformity from a bunion is called a bunionectomy, which typically involves removing bony growth of the bunion, re-positioning ligaments and tendons, and realigning the bones of the toe joint. Surgery is usually a day procedure performed with a local anaesthetic. The bones may be stabilised in their new position with screws or pins. Hardware may even include absorbable pins that are broken down by the body after a few months. You can expect a 6 - 8 week recovery period during which crutches are usually required. Surgery is often successful but sometimes the big toe moves back to its previous deviated position. Proper footwear and orthotics reduces the chances of surgical failure.

Prevention
The best protection against developing bunions is to protect and care for your feet every day. Avoid tight and narrow-fitting shoes. Limit your use of high heels. Wear comfortable shoes with adequate space between your longest toe and the end of the shoe. Getting treatment for very flat or very high-arched feet (if you are experiencing symptoms) will give your feet the proper support and help maintain stability and balance.

Overview
Your arch, made up of your tarsals and metatarsals, bridges the area between your heel and the ball of the foot. The ball of the foot is formed where the metatarsals meet your toes. It creates the base area that you use to support your weight whenever you lift your heels off the ground, whether you?re walking, running, jumping, or just rising up on your toes. Conditions of these structures can make it very uncomfortable to walk.


Causes
Often, tarsal tunnel syndrome is misdiagnosed and confused with plantar fasciitis. Tarsal tunnel syndrome is when the tibial nerve which runs through the ankle, is pinched as it passes through the flexor retinaculum, the supportive band that surrounds the ankle joint. The symptoms of tarsal tunnel syndrome are often limited to the ankle but the since the nerve passes through the entire foot it can cause arch pain. Arch pain associated with foot strain is mainly caused by a pronated foot (rolls inward) or a flat foot. These are usually not singular causes of arch pain, but in combination with other factors, arch pain may result.

Symptoms
The muscle imbalance around the foot and ankle gives rise to a typical pattern of deformity in addition to the high arch (known as cavus). The bone under the big toe (called the first metatarsal) can become very prominent and the toes can curl or clench like a fist (called claw toes). Excessive amount of weight may be placed on the ball and heel of the foot, which can lead to the ankle weakening and giving way (this is referred to as ankle instability) and soreness. Calluses and sometimes stress fractures may occur where the foot is exposed to extra friction or pressure, such as on the outer (or lateral) border of the foot.

Diagnosis
To come to a correct diagnosis, your podiatrist will examine your foot by using his or her fingers to look for a lump or stone bruise in the ball of your foot. He or she will examine your foot to look for deformities such as high or low arches, or to see if you have hammertoes. He or she may use x-rays, MRIs (magnetic resource imaging), and CT scans to rule out fractures and damage to ligaments, tendons, and other surrounding tissues. Your doctor will also inquire about your daily activities, symptoms, medical history, and family history. If you spend a lot of time running or jumping, you may be at a higher risk for pain in the bottom of your foot. These diagnostic tests will help your doctor come to a proper diagnosis and create an appropriate treatment plan.

Non Surgical Treatment
What remedies work best depends on the source of your pain. Stretches help tightened, overused muscles to relax, and exercises help weakened ones to regain the strength they need to hold your foot in its proper place. Prescription orthotics add extra support and help your arch more efficiently distribute weight. Changing your shoes to ones that better cushion and brace your foot also help. Generally flatfoot pain doesn?t require surgery, unless the problem was caused by a torn tendon. You may then need a procedure to repair the damaged tissue and realign your arch.


Surgical Treatment
Surgery may be necessary in situations where the symptoms are likely to get worse over time, or when pain and instability cannot be corrected with external orthopedic devices. There are many types of surgical procedures, including cavus foot reconstruction, which can be performed to correct the foot and the ankle and restore function and muscle balance.


Prevention
There are several things that you can do to prevent and treat arch pain. This includes Avoiding high heeled shoes, Stretching the calf muscles regularly, Wearing well fitted, comfortable shoes, Using customisedorthotic devices or shoe inserts, Elevating the feet and applying ice and taking over-the-counter anti-inflammatory medications. You can also care for your feet by paying attention to any changes in your feet as you get older. It is normal for feet to lose some of their fat pads as a person ages. Your feet may get bigger, both wider and longer as well. Make sure that you wear shoes that are sturdy, but comfortable, and have your feet measured before you buy shoes to make sure that you are still wearing the right size. Shoe sizes vary from one brand to the next, so it is a good idea to have your feet measured every time you purchase shoes. When choosing shoes, match the shoe to the activity for which it will be worn. Within the broader grouping of athletic shoes, there are different categories with different features. For example, a running shoe has different features than a walking shoe. You may develop some arthritic changes in your feet over time, too. If you notice that you are experiencing more pain in your feet, see your doctor for an evaluation. If the pain is arthritis-related, your doctor may recommend medication or other treatment to slow the progression of the arthritis.

Stretching Exercises
Gastroc stretch. Stand on the edge of a step. Rise slowly on your toes. Lower yourself slowly as far as you can until you feel a stretch in your calf. Don?t roll your foot inward or outward. Hold for 1-2 seconds. Reps:10-20 (stop before you fatigue). Soleus stretch. Same as above, but start with your knee bent so that you feel a slight stretch in your calf or achilles. Maintain the angle of your knee throughout the stretch. Bicycle stretch. Lie on your side. Keeping your top leg straight, bring your knee toward your nose until you feel a slight stretch in the hamstring. Maintaining this angle at your hip, start pretending you are pedalling a bicycle with the top leg. Make sure you feel a slight stretch each time your knee is straight. Reps: 10-30 for each leg. If you feel any pops or clicks in your hip or back, try raising the top leg a little (making the thighs further apart) to eliminate the popping. Foot Intrinsic Exercises. Assisted metatarsal head raising. Sit in a chair. Find the bumps at the ball of your foot just before your big toe and just before the little toe. These are the first (big toe) and fifth (little toe) metatarsal heads. Place your second and third fingers from one hand under the first metatarsal head, and the second and third fingers from the other hand under the fifth metatarsal head. Now lay the thumbs from each hand in a diagonal across your toes so that they form a right angle meeting at the nail of the second toe. Your hands are now in position to assist your toes. Keep your toes straight, with the toe pads on the floor. Use your fingers to help raise all the metatarsal heads (the ball of your foot). Do not let your toes curl under keep them long. Now relax. Reps 7-10 for each foot. As this exercise gets easier, let your fingers do less of the work until your toes can do the exercise unassisted. This can take up to three weeks. When your strength has improved to this point, you can progress to the following three exercises, which are best done in stocking feet on a slippery floor. Active metatarsal head raising. Stand with your weight on both feet. Raise your metatarsal heads (the ball of your foot) while keeping your toes from curling under and maintaining your heel on the ground. Relax. Reps 6-7. Do one foot at a time. If you do more reps than you are ready for, you may well develop cramping in your foot. I once had a client who thought if seven reps were good, 10 were better. For good measure, she did the 10 reps 10 times in a day, and then she was unable to walk the next day from having used a set of muscles she had never exercised before. Don?t overdo it.

Overview
The arch of the foot is made from a complex series of bones tendons and ligaments. According to podiatric practice there is only one important arch of the foot on the medial side. The height of the arch varies and having a flat foot or high arched foot is inherited. The arch acts to dissipate forces and store energy within the foot. Most young children have flat feet and this is because the arch has fatty tissue overlying it. Normally an arch appears after the age of 5-6 years. Even if you remain flat footed this might be normal for you and your family. Just because the arch is low does not mean that any treatment is required. Many world class athletes have flat feet. If the arch is painful or the arch of one foot suddenly drops then investigation and treatment may be required. The arch might drop acutely due to a tear in a tendon or the movement of a bone within the arch. A scan and X Ray may be indicated and treatment ranging from insoles to surgery may be required. If you have a high arched foot this is likely to have been inherited. In extreme form this can cause pain in the ball of the foot and is often associated with a tight Achilles tendon and a tendency to walk on the outside of your foot. In most people there are no symptoms and in others there may pain along the arch and pain on the outside of your ankle. Both these foot types are often mild and require no treatment, but if symptoms occur a full bio-mechanical examination will often reveal a mechanical cause to your pain. Often the treatment may be simple stretches and orthoses.


Causes
Spending a lot of time on your feet. Especially when you are not used to doing so. For example you may have started a new job such as waiting tables where you are on your feet all day and wake up the next day with sore feet. This is a sign of damage and over time could lead to plantar fasciitis. Being Over-Weight. Never an easy topic to discuss but in simple terms, the heavier you are, the greater the burden on your feet. There are times when you're walking when your entire body weight is borne on one leg and therefore one foot, placing great strain on the plantar fascia. Wearing shoes with poor arch support or cushioning. A tight Achilles tendon. This is the big tendon at the bottom of your calf muscles above your heel. If this is excessively tight this can affect your ability to flex your ankle and make you more likely to damage your plantar fascia. Suddenly changing your exercise routine. Using running as an example if you suddenly run many more miles than your are used to or change to a new running surface e.g. grass to tarmac - these factors can put excessive strain on the plantar fascia and lead to plantar fasciitis. All of these risk factors ultimately lead to a specific change in foot structure. The term given is over-pronation and this basically describes rolling in of the foot and lowering of the arches. It is this change that excessively elongates the plantar fascia which can lead to plantar fasciitis.

Symptoms
The majority of children and adults with flexible flatfeet never have symptoms. However, their toes may tend to point outward as they walk, a condition called out-toeing. A person who develops symptoms usually complains of tired, aching feet, especially after prolonged standing or walking. Symptoms of rigid flatfoot vary depending on the cause of the foot problem.

Diagnosis
Magnetic Resonance Imaging (MRI) can show tendon injury and inflammation but cannot be relied on with 100% accuracy and confidence. The technique and skill of the radiologist in properly positioning the foot with the MRI beam are critical in demonstrating the sometimes obscure findings of tendon injury around the ankle. Magnetic Resonance Imaging (MRI) is expensive and is not necessary in most cases to diagnose posterior tibial tendon injury. Ultrasound has also been used in some cases to diagnose tendon injury, but this test again is usually not required to make the initial diagnosis.

Non Surgical Treatment
Though most FFF are asymptomatic (no pain or discomfort), they should still be addressed as it is not normal to have flat feet. Obviously it is always ideal to prevent a problem rather than treat it after it occurs, especially if FFF is being treated post-foot development. As mentioned earlier, barefoot is the best way to prevent FFF and a host of other foot and gait imbalances. To truly strengthen the entire foot and all the arches, it?s important to position the foot correctly at all times so when wearing something on the feet, footwear should be flat, firm, and flexible. This means that the shoe should not have a significant, or any, heel to toe drop, there should be little to no cushion or padding in the sole, and the shoe should not be rigid anywhere - it should bend throughout the shoe and in any direction. The shoe should also be wide at the toe box allowing the toes to naturally splay apart.


Surgical Treatment
Cavus foot is caused in part by an over-pull of one of the lateral ankle muscles. A release of this tendon can be performed on the outside of the ankle. Additionally, a transfer of this tendon can be performed to help in correcting deformity of the ankle joint. Often patients will have a tightness of their gastrocnemius muscle, one of the main muscles in the calf. This can increase the deformity or prevent a correction from working. It is addressed with a lengthening of a part of the calf muscle or Achilles tendon. This is often performed through one or more small cuts in the back of the leg or ankle. Finally, the plantar fascia may be tight. The plantar fascia is a cord-like structure that runs from the heel to the front part of the foot. Partial or complete plantar fascia release may be done.


Prevention
There are several things you can do to prevent pain on the bottom of the foot. Here are some tips to help you avoid this condition. Do simple stretches each day (See Plantar Fasciitis Exercises for a list of all exercises). Wear good shoes that fit properly and are appropriate for the activity you are participating in. Lose excess weight if possible. Build your stamina slowly, especially with new exercises. Rest and elevate your feet, whenever possible, keeping them at least twelve inches above your heart. Always follow your doctor?s instructions for treatment. Each day do a different activity. For example: one day ride your bike, and swim the next day.

Overview

The Achilles tendon is the tough sinew that attaches the calf muscle to the back of the calcaneus, or heel bone. It is also known as the tendo calcaneus or the tendo Achilles and happens to be one of the longest tendons in the body. An Achilles tendon rupture occurs when the Achilles tendon is partially or completely broken or torn. The average age of patients who suffer Achilles tendon ruptures is 30 to 40 years. The male-to-female ratio is nearly 20 to 1.

Causes
Factors that may increase your risk of Achilles tendon rupture include Age. The peak age for Achilles tendon rupture is 30 to 40. Your sex. Achilles tendon rupture is up to five times more likely to occur in men than in women. Playing recreational sports. Achilles tendon injuries occur more often in sports that involve running, jumping and sudden starts and stops - such as soccer, basketball and tennis. Steroid injections. Doctors sometimes inject steroids into an ankle joint to reduce pain and inflammation. However, this medication can weaken nearby tendons and has been associated with Achilles tendon ruptures. Certain antibiotics. Fluoroquinolone antibiotics, such as ciprofloxacin (Cipro) or levofloxacin (Levaquin), increase the risk of Achilles tendon rupture.

Symptoms
A sudden and severe pain may be felt at the back of the ankle or calf, often described as "being hit by a rock or shot" or "like someone stepped onto the back of my ankle." The sound of a loud pop or snap may be reported. A gap or depression may be felt and seen in the tendon about 2 inches above the heel bone. Initial pain, swelling, and stiffness may be followed by bruising and weakness. The pain may decrease quickly, and smaller tendons may retain the ability to point the toes. Without the Achilles tendon, though, this would be very difficult. Standing on tiptoe and pushing off when walking will be impossible. A complete tear is more common than a partial tear.

Diagnosis
A consultation and physical exam with a qualified musculoskeletal expert is the first step. X-ray or MRI scanning may be required for a diagnosis. Once a rupture is diagnosed it should be treated to prevent loss of strength and inadequate healing.

Non Surgical Treatment
Your doctor may advise you to rest your leg and keep the tendon immobile in a plaster cast while it heals. Or you may need to have an operation to treat an Achilles tendon rupture. The treatment you have will depend on your individual circumstances, such as your age, general health and how active you are. It will also depend on whether you have partially or completely torn your tendon. If you have a partial tear, it might get better without any treatment. Ask your doctor for advice on the best treatment for you. If you need pain relief, you can take over-the-counter painkillers such as paracetamol or ibuprofen. Always read the patient information that comes with your medicine and if you have any questions, ask your pharmacist for advice.


Surgical Treatment
Thanks to a new surgical technique, operative procedures are often more beneficial.The operative treatment of Achilles tendon ruptures has significantly changed in recent years. The objective today is to connect the torn tendons using modern suture and possibly adhesive materials. Through small surgical incisions the ends of the torn tendon are surgically exposed, and sutures are used to tie the ends permanently together. Thus, the operated repaired tendon is again resilient within a reasonable time. The cast treatment and walking on crutches required in the past, is with this procedure usually not necessary. Instead, functional treatment following the surgery involves wearing a special boot, meaning that the patient can put weight onto the operated leg again within a few days after surgery. Physical therapy training will start immediately following the operation. The philosophy behind such an early functional treatment is that tissue adequately adapts to stress and thus accelerates the healing process. For the patient, the modern surgical treatment of an Achilles tendon rupture has the distinct advantage that no prolonged hospital stay is necessary. Hospital stay usually lasts only a few days. Using crutches, patients can return to work soon after the surgery.

Prevention
To help reduce your chance of getting Achilles tendon rupture, take the following steps. Do warm-up exercises before an activity and cool down exercises after an activity. Wear proper footwear. Maintain a healthy weight. Rest if you feel pain during an activity. Change your routine. Switch between high-impact activities and low-impact activities. Strengthen your calf muscle with exercises.

Overview
The majority of people will experience a flattening of the arch of the feet as we age. This is a natural part of the aging process for most, as the years of abuse we put on our feet causes weakening of the soft tissue structures that support the arch of the foot and gravity dictates that the feet tend to flatten out. When flattening of one of the feet occurs rapidly over a relatively short period of time this may signal a more serious problem.


Causes
There are multiple factors contributing to the development of this problem. Damage to the nerves, ligaments, and/or tendons of the foot can cause subluxation (partial dislocation) of the subtalar or talonavicular joints. Bone fracture is a possible cause. The resulting joint deformity from any of these problems can lead to adult-acquired flatfoot deformity. Dysfunction of the posterior tibial tendon has always been linked with adult-acquired flatfoot deformity (AAFD). The loss of active and passive pull of the tendon alters the normal biomechanics of the foot and ankle. The reasons for this can be many and varied as well. Diabetes, high blood pressure, and prolonged use of steroids are some of the more common causes of adult-acquired flatfoot deformity (AAFD) brought on by impairment of the posterior tibialis tendon. Overstretching or rupture of the tendon results in tendon and muscle imbalance in the foot leading to adult-acquired flatfoot deformity (AAFD). Rheumatoid arthritis is one of the more common causes. About half of all adults with this type of arthritis will develop adult flatfoot deformity over time. In such cases, the condition is gradual and progressive. Obesity has been linked with this condition. Loss of blood supply for any reason in the area of the posterior tibialis tendon is another factor. Other possible causes include bone fracture or dislocation, a torn or stretched tendon, or a neurologic condition causing weakness.

Symptoms
The symptoms of PTTD may include pain, swelling, a flattening of the arch, and an inward rolling of the ankle. As the condition progresses, the symptoms will change. For example, when PTTD initially develops, there is pain on the inside of the foot and ankle (along the course of the tendon). In addition, the area may be red, warm, and swollen. Later, as the arch begins to flatten, there may still be pain on the inside of the foot and ankle. But at this point, the foot and toes begin to turn outward and the ankle rolls inward. As PTTD becomes more advanced, the arch flattens even more and the pain often shifts to the outside of the foot, below the ankle. The tendon has deteriorated considerably and arthritis often develops in the foot. In more severe cases, arthritis may also develop in the ankle.

Diagnosis
There are four stages of adult-acquired flatfoot deformity (AAFD). The severity of the deformity determines your stage. For example, Stage I means there is a flatfoot position but without deformity. Pain and swelling from tendinitis is common in this stage. Stage II there is a change in the foot alignment. This means a deformity is starting to develop. The physician can still move the bones back into place manually (passively). Stage III adult-acquired flatfoot deformity (AAFD) tells us there is a fixed deformity. This means the ankle is stiff or rigid and doesn???t move beyond a neutral (midline) position. Stage IV is characterized by deformity in the foot and the ankle. The deformity may be flexible or fixed. The joints often show signs of degenerative joint disease (arthritis).

Non surgical Treatment
Get treated early. There is no recommended home treatment. While in stage one of the deformity, rest, a cast, and anti-inflammatory therapy can help you find relief. This treatment is followed by creating custom-molded foot orthoses and orthopedic footwear. These customized items are critical in maintaining the stability of the foot and ankle. Once the tendon has stretched and deformity is visible, the chances of success for non-surgical treatment are significantly lower. In a small percentage of patients, total immobilization may arrest the progression of the deformity. A long-term brace known as an ankle foot orthosis is required to keep the deformity from progressing. The Richie Brace, a type of ankle foot orthosis, shows significant success as a treatment for stage two posterior tibial dysfunction. It is a sport-style brace connected to a custom corrected foot orthodic that fits into most lace-up footwear (including athletic shoes). It is also light weight and more cosmetically appealing than traditionally prescribed ankle foot orthosis. The Arizona Brace, California Brace or Gauntlet Brace may also be recommended depending on your needs.


Surgical Treatment
Good to excellent results for more than 80% of patients have been reported at five years' follow up for the surgical interventions recommended below. However, the postoperative recovery is a lengthy process, and most surgical procedures require patients to wear a plaster cast for two to three months. Although many patients report that their function is well improved by six months, in our experience a year is required to recover truly and gain full functional improvement after the surgery. Clearly, some patients are not candidates for such major reconstructive surgery.
