Overview
When a person has Hammertoes, the end of their toe bends downward and the middle joint curls up. Eventually, the toe gets stuck in a stiff, claw-like position. When the inside of your shoe rubs against a hammer toe, corns, blisters or calluses may form on top of the toe or on the bottom of your foot. This can make walking painful. You may also have pain in the joint where your big toe joins your foot. Hammer toe usually affects a person?s second toe (the toe next to the big toe), but it can affect other toes too.

Causes
Many people develop hammertoe because they wear shoes that are too tight. Shoes with narrow toe boxes squeeze the toes together, forcing some to bend. This causes the toe muscles to contract. If the toes are forced into this cramped position too often, the muscles may permanently tighten, preventing the toes from extending. Chronic hammertoe can also cause the long bones that connect the toes to the foot, called metatarsals, to move out of position. The misaligned metatarsal bones may pinch a nerve running between them, which can cause a type of nerve irritation called a neuroma.

Symptoms
A toe (usually the second digit, next to the big toe) bent at the middle joint and clenched into a painful, clawlike position. As the toe points downward, the middle joint may protrude upward. A toe with an end joint that curls under itself. Painful calluses or corns. Redness or a painful corn on top of the bent joint or at the tip of the affected toe, because of persistent rubbing against shoes Pain in the toes that interferes with walking, jogging, dancing, and other normal activities, possibly leading to gait changes.

Diagnosis
Although hammertoes are readily apparent, to arrive at a diagnosis the foot and ankle surgeon will obtain a thorough history of your symptoms and examine your foot. During the physical examination, the doctor may attempt to reproduce your symptoms by manipulating your foot and will study the contractures of the toes. In addition, the foot and ankle surgeon may take x-rays to determine the degree of the deformities and assess any changes that may have occurred.

Non Surgical Treatment
Apply a commercial, nonmedicated hammertoe pad around the bony prominence of the hammertoe. This will decrease pressure on the area. Wear a shoe with a deep toe box. If the hammertoe becomes inflamed and painful, apply ice packs several times a day to reduce swelling. Avoid heels more than two inches tall. A loose-fitting pair of shoes can also help protect the foot while reducing pressure on the affected toe, making walking a little easier until a visit to your podiatrist can be arranged. It is important to remember that, while this treatment will make the hammertoe feel better, it does not cure the condition. A trip to the podiatric physician?s office will be necessary to repair the toe to allow for normal foot function. Avoid wearing shoes that are too tight or narrow. Children should have their shoes properly fitted on a regular basis, as their feet can often outgrow their shoes rapidly. See your podiatric physician if pain persists.

Surgical Treatment
Sometimes, if the deformity is severe enough or surgical modification is needed, the toe bones may be fused so that the toe does not bend. Buried wires are used to allow for the fusion to heal, and they remain in place after healing. Your skin is closed with fine sutures, which are typically removed seven to ten days after surgery. A dressing is used to help keep your toes in their new position. Dressings should not get wet or be removed. After surgery, your doctor may prescribe pain relievers, typically for the initial four to seven days. Most people heal completely within one month of surgery, with few complications, if any. Crutches or a cane may be needed to help you keep weight off your affected foot, depending on the procedure. Occasionally, patients receive a special post-op shoe or a walking boot that is to be worn during the healing process. Most people are able to shower normally after surgery, but must protect the dressing from getting wet. Many patients are allowed to resume driving within one week after the procedure, but care needs to be taken.

Overview
When there?s an imbalance in the muscle and ligament surrounding a toe joint, the effect is a bend in the middle joint of the toe, which causes the whole toe to bend upward. Because the toe is bent in an unnatural way, it?s common for the toe to become irritated and even develop corns. A toe that curls under rather than bends upward is also considered a Hammer Toe.

Causes
Poorly fitting shoes and muscle imbalances are the most common causes of hammertoe. When shoes are too narrow or do not accommodate the shape and size of your feet, they often contort the position of your toes. Choosing a shoe that fits is very important when it comes to avoiding foot problems like bunions or hammertoe. Having your toes bent for an extended period of time in a shoe that is too narrow or small forces your toes to adapt to the cramped space. With time, the muscles in your feet become accustomed to holding the flexed position of your toes, making it harder, or even impossible to straighten them.

Symptoms
Some people never have troubles with hammer toes. In fact, some people don't even know they have them. They can become uncomfortable, especially while wearing shoes. Many people who develop symptoms with hammer toes will develop corns, blisters and pain on the top of the toe, where it rubs against the shoe or between the toes, where it rubs against the adjacent toe. You can also develop calluses on the balls of the feet, as well as cramping, aching and an overall fatigue in the foot and leg.

Diagnosis
Your doctor is very likely to be able to diagnose your hammertoe simply by examining your foot. Even before that, he or she will probably ask about your family and personal medical history and evaluate your gait as you walk and the types of shoes you wear. You'll be asked about your symptoms, when they started and when they occur. You may also be asked to flex your toe so that your doctor can get an idea of your range of motion. He or she may order x-rays in order to better define your deformity.

Non Surgical Treatment
Pad it. Mild cases of hammertoe can be treated with corn pads or felt pads available in the pharmacy. Toe caps, the small, padded sleeves that fit around the tip of the toe, may relieve hammer toe pain. Change your shoes. Wear wide shoes with resilient soles. Avoid shoes with pointed toes. Exercise. Certain exercises such as moving and stretching your toe gently with your hands and picking small or soft objects such as marbles or towels can keep your toe joints flexible. Also, while you are watching television or reading, you can also put a towel flat under your feet and use your toes to crumple it. This simple exercise can stretch and strengthen your muscles. Use ice. If your hammer toe becomes painful, applying an ice pack several times a day can help relieve the soreness and swelling.
Take medications. Nonsteroidal anti-inflammatory medicines (also called NSAIDs), such as ibuprofen or naproxen may be helpful in minimizing pain and inflammation. Use orthotic devices. Place a custom orthotic device in your shoe. This will help control the muscle/tendon imbalance.

Surgical Treatment
Surgery to correct for a hammertoe may be performed as an outpatient procedure at a hospital, surgery center, or in the office of your podiatrist. There are multiple procedures that can be used depending on your individual foot structure and whether the deformity is flexible or rigid. There may be a surgical cut in the bone to get rid of an exostosis, or a joint may be completely removed to allow the toe to lay straight.

Overview
There are two different types of Hammer toes. Flexible Hammer Toes. These hammer toes are less serious because they can be diagnosed and treated while still in the developmental stage. They are called flexible hammer toes because they are still moveable at the joint. Rigid Hammer Toes. This variety is more developed and more serious than the flexible condition. Rigid hammer toes can be seen in patients with severe arthritis, for example, or in patients who wait too long to seek professional treatment. The tendons in a rigid hammer toe have become tight, and the joint misaligned and immobile, making surgery the usual course of treatment.

Causes
The constant pressure a woman's foot receives in high-heeled shoes due to the force of gravity causes their feet to naturally slide down and press on the lowest point of the shoe so they are not able to receive enough space and stretch out. The result is an eventual distortion of the woman's toes. The deformity comes as a result of the shortening of muscles inside the toes because the toes become used to being in a bent position, prompting the muscles to fail to extend any further and become tightened and curbed. At first, toes may still be stretched out if poor footwear is not being worn, yet if the habit is persistent...the person's toes will eventually become used to the position they are constantly in and muscle fibers inside them will harden and refuse to stretch.

Symptoms
If the toes remain in the hammertoe position for long periods, the tendons on the top of the foot will tighten over time because they are not stretched to their full length. Eventually, the tendons shorten enough that the toe stays bent, even when shoes are not being worn. The symptoms of hammertoe include a curling toe, pain or discomfort in the toes and ball of the foot or the front of the leg, especially when toes are stretched downward, thickening of the skin above or below the affected toe with the formation of corns or calluses, difficulty finding shoes that fit well. In its early stages, hammertoe is not obvious. Frequently, hammertoe does not cause any symptoms except for the claw-like toe shape.

Diagnosis
Most health care professionals can diagnose hammertoe simply by examining your toes and feet. X-rays of the feet are not needed to diagnose hammertoe, but they may be useful to look for signs of some types of arthritis (such as rheumatoid arthritis) or other disorders that can cause hammertoe.

Non Surgical Treatment
Your podiatrist may recommend one or more of these treatments to manage your hammer toes. Wear shoes with roomy toe boxes which don?t force your toes together. Exercises to stretch and strengthen muscles in the toes. Over the counter toe straps, cushions, and corn pads. Custom orthotic inserts. Toe caps or toe slings. In severe cases, surgery to release the muscles in the affected toes.

Surgical Treatment
If a person's toes have become very inflexible and unresponsive to non-invasive means of treatment and if open sores have developed as a result of constant friction, they may receive orthopaedic surgery to correct the deformity. The operation is quick and is commonly performed as an out-patient procedure. The doctor administers a local anesthetic into the person's foot to numb the site of the operation. The person may remain conscious as the surgeon performs the procedure. A sedative might also be administered to help calm the person if they are too anxious.

Prevention
Preventative treatment of hammertoe is directed toward the cause of the deformity. A functional orthotic is a special insert that can be prescribed by your podiatrist to address the abnormal functioning of the foot that causes the hammertoe. Functional orthotics can be thought of as contact lenses for your feet. They correct a number of foot problems that are caused by an abnormally functioning foot. Our feet, much like our eyes, change with time. Functional orthotics slow down or halt this gradual change in the foot. Often when orthotics are used for flexible hammertoes, the toes will overtime straighten out and correct themselves. Calf stretching exercises are also helpful. Calf stretching can help to overcome part of the muscle imbalance that causes the hammertoe.

Overview

More than one-third of women in America have bunions, a common deformity often blamed on wearing tight, narrow shoes and high heels. Bunions may occur in families, but many are from wearing tight shoes, and nine out of 10 bunions happen to women. Too-tight shoes can also cause other disabling foot problems such as corns, calluses and hammer toes.

Causes
Bunions form when the normal balance of forces that is exerted on the joints and tendons of the foot becomes disrupted. This disruption can lead to instability in the joint and cause the deformity. Bunions are brought about by years of abnormal motion and pressure over the MTP joint. They are, therefore, a symptom of faulty foot development and are usually caused by the way we walk and our inherited foot type or our shoes.
SymptomsThe initial symptom may be pain at the joint prominence when wearing certain shoes. The joint capsule may be tender at any stage. Later symptoms may include a painful, warm, red, cystic, movable, fluctuant swelling located medially (adventitial bursitis) and swellings and mild inflammation affecting the entire joint (osteoarthritic synovitis), which is more circumferential. With hallux limitus or rigidus, there is restriction of passive joint motion, tenderness at the dorsolateral aspect of the joint, and increased dorsiflexion of the distal phalanx.

Diagnosis
Before examining your foot, the doctor will ask you about the types of shoes you wear and how often you wear them. He or she also will ask if anyone else in your family has had bunions or if you have had any previous injury to the foot. In most cases, your doctor can diagnose a bunion just by examining your foot. During this exam, you will be asked to move your big toe up and down to see if you can move it as much as you should be able to. The doctor also will look for signs of redness and swelling and ask if the area is painful. Your doctor may want to order X-rays of the foot to check for other causes of pain, to determine whether there is significant arthritis and to see if the bones are aligned properly.

Non Surgical Treatment
Some bunions can be treated without surgery. If you have a bunion, wear shoes that are roomy enough so that they won?t put pressure on it. You can choose to have your shoes stretched out professionally or try cushioning the painful area with protective pads. Orthotics have been shown to help prevent progression of bunions. Oral nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be recommended to reduce pain and inflammation. Applying an ice pack several times a day can also help reduce inflammation and pain. If your bunion progresses to a point where you have difficulty walking or experience pain even with accommodative shoes, surgery may be necessary.


Surgical Treatment
Surgical options, such as a bunionectomy, can remove the bunion and realign the toe. There are several types of surgeries to fix the bunion. The type of bunion you have along with other factors such as the degree of severity and underlying cause of the bunion will determine which approach would be most beneficial for you.

Prevention
The simplest way to reduce your chance of developing foot bunion or bunionette problems is to wear good-fitting shoes. Avoid high heels as they push your feet forwards to the front of the shoe where they get squashed. Also avoid narrow fitting shoes, especially those that are pointed at the front with a narrow toe box as again, these place pressure through the toes pushing them inwards. Shoes should be comfortable and leave enough room for you to wiggle your toes. Remember, bunions rarely affect non-shoe wearing people. Exercising your feet can also help. By strengthening the foot muscles you can improve your foot position which can help reduce foot bunion problems. Simple exercises like picking up small objects with your toes can help.

Overview
The arch of the foot is formed by the tarsal and metatarsal bones and is strengthened by ligaments and tendons that enable the foot to correctly support the weight of the body. The underside of the foot is made up of four layers of muscle tissue as well as a length of thick connective tissue called the plantar fascia, which supports the arch. If the surrounding muscles weaken, the plantar fascia will drop and the arch will collapse. If the arch collapses, the whole foot touches the ground, which is known as pes planus or flat feet. Flat feet affect about 15 per cent of Britons. Although usually genetic, the condition may be exacerbated or triggered by poorly fitted shoes or conditions such as arthritis and pregnancy, when sudden changes in shape and weight can alter the body's centre of gravity leading to a weakening of the arches.


Causes
Plantar fasciitis, another sports injury detailed on this website, is regularly the cause of foot arch pain or strain. This can arise due to faulty biomechanics in your feet, which alone can also provoke foot arch pains. The most prominent biomechanical difficulties are flat feet and high arches. With flat feet (or overpronation) the arches appear to be almost flattened, causing unevenness by forcing the feet roll inwards in order to maintain balance and support the body's weight. This places inordinate pressure on the plantar fascia and arches. If by contrast you have high arches (instep), the ankle can roll outwards, again causing undue strain on the arches. Too much of this strain can lead to stretching of the plantar fascia and pain in the arches. Other causes include overstretching or otherwise pressuring the arches, for example by exercising with fatigued leg muscles which leave the feet with excessive work to do. You are also particularly at risk if in your 40s or 50s and commencing an intense program of training after a long period of inactivity.

Symptoms
Plantar fasciitis is most often seen in middle-aged men and women, but can be found in all age groups. The condition is diagnosed with the classic symptoms of pain well focused deep in the heel area of the bottom of the foot. Often the pain from plantar fasciitis is most severe when you first stand on your feet in the morning. Pain often subsides quite quickly, but then returns after prolonged standing or walking. Plantar fasciitis is sometimes, but not always, associated with a rapid gain of weight. It is also sometimes seen in recreational athletes, especially runners. In these athletes, it is thought that the repetitive nature of the sports causes the damage to the fibrous tissue that forms the arch of the foot.

Diagnosis
In more difficult cases of plantar fasciitis you should see your foot health professional for a thorough examination. They will find out why your arch or heel pain occurred in the first place and devise a treatment plan to relieve your pain and prevent it from reoccurring. They will evaluate your feet, walking pattern (gait), shoes, activities, exercise methods, and other relevant information and then devise your treatment plan.

Non Surgical Treatment
The most effective treatment for foot arch pain and strain is to use an arch support. The arch support sits under the foot and stops the arch of the foot from collapsing, thereby preventing the stretch of the arch pad which causes pain and discomfort. Wearing an arch support in slippers or house shoes can also prevent pain in the mornings when discomfort it most common and severe. Arch supports usually relieve symptoms within a few days.


Surgical Treatment
Patients with adult acquired flatfoot are advised to discuss thoroughly the benefits vs. risks of all surgical options. Most procedures have long-term recovery mandating that the correct procedure be utilized to give the best long-term benefit. Most flatfoot surgical procedures require six to twelve weeks of cast immobilization. Joint fusion procedures require eight weeks of non-weightbearing on the operated foot, meaning you will be on crutches for two months. The bottom line is: Make sure all of your non-surgical options have been covered before considering surgery. Your primary goals with any treatment are to eliminate pain and improve mobility. In many cases, with the properly designed foot orthosis or ankle brace, these goals can be achieved without surgical intervention.


Prevention
Arch pain occurs when the plantar fascia becomes worn down due to constant strain or excessive exercising. This may be caused by increasing your running or hiking mileage too fast, wearing inadequate footwear, lack of stretching, running on steep hills, standing on your feet for too long and abnormal anatomy such as flat foot. Stretching is an important exercise that should not be overlooked because the tightness or lack of tightness of the joints in the foot can also cause pain in the arch.

Stretching Exercises
Easy Beginner Version. Start with your bare foot on a flat surface, toes spread out. Place a penny under the ball of your foot and the end of a pen under the middle of your arch (sticking out from the inside of your foot). Activate your arch by flexing your arch muscle. You should feel the muscles on the ball of your foot pushing down on the penny, but your arch shouldn't be pushing down on the pen. These tools help you (1) avoid rolling your foot and (2) avoid pressing down with your toes (as an extra tip, you can slide a business card under your toes before doing the exercise-when you activate your arch, you should be able to slide the business card out easily with your fingers). Do your best to keep your toes relaxed. Advanced Version. Once you're ready to move on, you can try this advanced version. It builds on the above exercise to incorporate full body twisting and balance, helping you to maintain proper arches while you move. Using the same ideas from above, stand on a flat surface in your bare feet with a penny under the ball of your foot and the end of a pen under your arch. This time, stand with your back a few inches away form a wall or a door. Lift your other leg (the one without the penny or pen) and stand on one foot. Use the wall for balance, if necessary. Lift one arm and stretch it across your body until you touch the wall or door on the opposite side, maintaining a straight back. Keep your foot straight and your arch on the penny but above the pen. Your arch will want to follow the movement and roll off, but you will need to activate it to stay stable during the movement. Lift your other arm and stretch it across the opposite side of your body, still keeping your arch in place.
