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 Toe 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
Hammertoe is caused when muscles fail to work in a balanced manner and the toe joints bend to form the hammertoe shape. If they remain in this position, the muscles and tendons supporting them tighten and stay that way. Causes of hammertoe can include squeezing into a too-small or ill-fitting shoe or wearing high heels that jam your toes into a tight toe box. An injury such as badly stubbing your toe. Arthritis. Nerve and muscle damage from diseases such as diabetes,

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
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
Any forefoot problems that cause pain or discomfort should be given prompt attention. Ignoring the symptoms can aggravate the condition and lead to a breakdown of tissue, or possibly even infection. Conservative treatment of mallet toes begins with accommodating the deformity. The goal is to relieve pressure, reduce friction, and transfer forces from the sensitive areas. Shoes with a high and broad toe box (toe area) are recommended for people suffering from forefoot deformities such as mallet toes. This prevents further irritation in the toe area from developing. Other conservative treatment includes forefoot supports such as gel toe caps, gel toe shields and toe crests. Gel forefoot supports provide immediate comfort and relief from common forefoot disorders without drying the skin.

Surgical Treatment
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 hammertoes, 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 podiatric physician.
