Overview
Patients and doctors often refer to all forms of toe abnormalities as a Hammer Toe. There are in fact four main forms of toe abnormalities, hammer toes, claw toes, mallet toes and trigger toes. A hammertoe can be best described as an abnormal contraction or "buckling" of a toe. This occurs due to a partial or complete dislocation of one of the joints that form the toe. As the toe continues to be deformed, it will press up against the shoe and may cause corns.

Causes
Hammer toe most frequently results from wearing poorly fitting shoes that can force the toe into a bent position, such as excessively high heels or shoes that are too short or narrow for the foot. Having the toes bent for long periods of time can cause the muscles in them to shorten, resulting in the hammer toe deformity. This is often found in conjunction with bunions or other foot problem (e.g., a bunion can force the big toe to turn inward and push the other toes). It can also be caused by muscle, nerve, or joint damage resulting from conditions such as osteoarthritis, rheumatoid arthritis, stroke, Charcot-Marie-Tooth disease, complex regional pain syndrome or diabetes. Hammer toe can also be found in Friedreich's ataxia.

Symptoms
Common symptoms of hammertoes include pain or irritation of the affected toe when wearing shoes. corns and calluses (a buildup of skin) on the toe, between two toes, or on the ball of the foot. Corns are caused by constant friction against the shoe. They may be soft or hard, depending upon their location. Inflammation, redness, or a burning sensation. Contracture of the toe. In more severe cases of hammertoe, open sores may form.

Diagnosis
The treatment options vary with the type and severity of each hammer toe, although identifying the deformity early in its development is important to avoid surgery. Your podiatric physician will examine and X-ray the affected area and recommend a treatment plan specific to your condition.

Non Surgical Treatment
Hammertoes that are not painful (asymptomatic) and still flexible may not require treatment. In mild cases, open-toed, low-heeled, or wider shoes and foam or moleskin pads can provide symptomatic relief by reducing pressure. Taping (strapping) the affected toe can help to reduce deformity and pain. Physical therapy to instruct patients in exercises that passively stretch tight structures and strengthen weak foot intrinsic muscles is also helpful with mild cases. Periodic trimming (debridement) of corns (clavi, helomata) by a podiatrist can provide temporary relief. Corticosteroid injections are often very effective in reducing pain.

Surgical Treatment
Probably the most frequent procedure performed is one called a Post or an Arthroplasty. In this case a small piece of bone is removed from the joint to straighten the toe. The toe is shortened somewhat, but there is still motion within the toe post-operatively. In other cases, an Arthrodesis is performed. This involves fusing the abnormally-contracted joint. The Taylor procedure fuses only the first joint in the toe, whereas the Lambrinudi procedure fuses both joints within the toe. Toes which have had these procedures are usually perfectly straight, but they take longer to heal and don't bend afterwards. A Hibbs procedure is a transfer of the toe's long extensor tendon to the top of the metatarsal bone. The idea of this procedure is to remove the deforming cause of the hammertoes (in this case, extensor substitution), but to preserve the tendon's function in dorsifexing the foot by reattaching it to the metatarsals. Fortunately, the Gotch (or Gotch and Kreuz) procedure--the removal of the base of the toe where it attaches to the foot, is done less frequently than in years past. The problem with this procedure is that it doesn't address the problem at the level of the deformity, and it causes the toe to become destabilized, often resulting in a toe that has contracted up and back onto the top of the foot. You can even have an Implant Arthroplasty procedure, where a small, false joint is inserted into place. There are several other procedures, as well.

Prevention
How can I prevent hammer toe? Avoid wearing shoes that are narrow or don?t fit well. Also, don?t wear heels higher than 2 inches. Instead, choose shoes with a wide toe box that give you ? inch between the end of your longest toe and the inside tip of the shoe. Check often to make sure your child?s shoes fit, especially when he or she is having a growth spurt.
