Overview
Hammer toe is defined as a deformity in the toe where part of the toe is permanently bent downward resembling a hammer. Two related conditions are mallet toe and claw toe which effect different toe joints in slightly different ways. The key difference is that Hammer toes tends to effect the middle joint in the toe (note: not the middle toe, the middle toe joint). The disease is usually associated with the second largest toe but can effect the third or fourth toe as well. Mallet toe effects the uppermost toe joint whereas claw toe is caused by the tow being held in a cramped ?claw-like? position.

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
A hammer toe may be painful, especially when irritated by a shoe. All four toe conditions may cause cramps in the toes, foot and leg due to the abnormal function of the tendons in the foot. If a mallet toe has occurred, you are likely to suffer from a corn at the end of the toe. A hammertoe may cause a corn on the top of the toe. Infections and ulcers can also occur. In severe cases a mallet toe, trigger toe, claw toe or a hammer toe may create a downward pressure on the foot, which can result in hard skin and corns on the soles of the feet.

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
The treatment options vary with the type and severity of each hammertoe, although identifying the deformity early in its development is important to avoid surgery. Podiatric medical attention should be sought at the first indication of pain and discomfort because, if left untreated, hammertoes tend to become rigid, making a nonsurgical treatment less of an option. Your podiatric physician will examine and X-ray the affected area and recommend a treatment plan specific to your condition.

Surgical Treatment
In advanced cases in which the toe has become stiff and permanently bent, the toe can be straightened with surgery. One type of surgery involves removing a small section of the toe bone to allow the toe to lie flat. Surgery for hammertoe usually is classified as a cosmetic procedure. Cosmetic foot surgeries sometimes result in complications such as pain or numbness, so it's better to treat the problem with a shoe that fits properly.

Prevention
The key to prevention is to wear shoes that fit you properly and provide plenty of room for your toes. Here?s how to get the right fit. Have your feet properly measured. The best way to do this is to get someone to draw the outline of your foot while you stand barefoot with your full weight on it, then measure the outline at the widest point. Measure the soles of your shoes. Ideally, they should be as wide as your feet, but certainly no more than half an inch narrower. Length matters, too, of course: your shoes should be half an inch longer than your longest toe.

Overview
Sometimes, the big toe can become angled outwards towards the middle of the foot and second toe. This forces the top of the first metatarsal to stick out from the side of the foot at the base of the big toe. If this happens, the bones can become misaligned and a painful bunion can form. It is not known exactly what causes bunions, but wearing badly fitting shoes is thought to make the condition worse. Research also suggests that bunions may run in families. It is thought that bunions are more likely to occur in people who have unusually flexible joints, and that this flexibility may be inherited. In some cases, certain health conditions, such as rheumatoid arthritis and gout, may also be responsible for the formation of bunions. These conditions cause pain and inflammation in the joints.

Causes
While the precise cause is not known, there seem to be inherited (genetic) factors that lead to abnormal foot function like overpronation that can predispose to the development of bunions. This is especially common when bunions occur in younger individuals. This abnormal biomechanics can lead to instability of the metatarsal phalangeal joint and muscle imbalance resulting in the deformity. Although shoe gear doesn't directly cause a bunion, it can certainly make the bunion painful and swollen. Other less common causes of bunion deformities include trauma (sprains, fractures, and nerve injuries), neuromuscular disorders (polio or Charcot-Marie-Tooth disease) and limb-length discrepancies (one leg shorter than the other) where the longer leg develops the bunion.

Symptoms
The most common symptoms associated with this condition are pain on the side of the foot. Shoes will typically aggravate bunions. Stiff leather shoes or shoes with a tapered toe box are the prime offenders. This is why bunion pain is most common in women whose shoes have a pointed toe box. The bunion site will often be slightly swollen and red from the constant rubbing and irritation of a shoe. Occasionally, corns can develop between the 1st and 2nd toe from the pressure the toes rubbing against each other. On rare occasions, the joint itself can be acutely inflamed from the development of a sac of fluid over the bunion called a bursa. This is designed to protect and cushion the bone. However, it can become acutely inflamed, a condition referred to as bursitis.

Diagnosis
Clinical findings are usually specific. Acute circumferential intense pain, warmth, swelling, and redness suggest gouty arthritis (see Gout) or infectious arthritis (see Acute Infectious Arthritis), sometimes mandating examination of synovial fluid. If multiple joints are affected, gout or another systemic rheumatic disease should be considered. If clinical diagnosis of osteoarthritic synovitis is equivocal, x-rays are taken. Suggestive findings include joint space narrowing and bony spurs extending from the metatarsal head or sometimes from the base of the proximal phalanx. Periarticular erosions (Martel sign) seen on imaging studies suggest gout.

Non Surgical Treatment
Nonsurgical treatments such as rest and wearing loose (wider) shoes or sandals can often relieve the irritating pain of bunions. Walking shoes may have some advantages, for example, over high-heeled styles that pressure the sides of the foot. Anti-inflammatory medications, such as acetylsalicylic acid (aspirin, Ecotrin), ibuprofen (Advil, Children's Advil/Motrin, Medipren, Motrin, Nuprin, PediaCare Fever) and naproxen (Anaprox, Naprelan, Naprosyn, Aleve), can help to ease inflammation as well as pain. Local cold-pack application is sometimes helpful as well. To reduce tension on the inner part of the joint of a bunion, stretching exercises are sometimes prescribed. Depending on the structure of the foot and severity of the bunion, custom insole orthotics can slow the progression of the bunion and address underlying biomechanical causes. Inflammation of the joint at the base of the big toe can often be relieved by a local injection of cortisone. Any signs of skin breakdown or infection can require antibiotics. When the measures above are effective in relieving symptoms, patients should avoid irritating the bunion again by optimizing footwear and foot care.

Surgical Treatment
If the above simple measures do not make you comfortable, an operation may improve the situation. An operation will not give you an entirely normal foot, but it will correct the deformity of the big toe and narrow your foot back towards a more desirable shape. There are a lot of different operations for bunions, depending on the severity of the deformity, the shape of your foot and whether arthritis has developed in the big toe joint. An orthopaedic surgeon who specialises in foot & ankle surgery can advise you on the best operation for your foot. However, an operation may not make your foot narrow enough to wear tight shoes, nor can it fully restore the strength of the big toe.

Prevention
Wear insoles and well-fitting shoes to help slow down the progression of bunions and alleviate discomfort. Cushioning can also help alleviate discomfort. Consider wearing shoes with a wide toe box so they don't crowd your toes. Children can also develop bunions and should wear properly fitting shoes as their feet are still developing.
