A hammertoe is a misshapen second, third, or fourth toe. The toe bends up at the middle joint. The toe becomes a hammertoe because a muscle in the toe isn?t working properly or is too weak, increasing pressure on the tendons and the toe joints. Muscles normally work in twos to bend and straighten toes. If the toe stays bent too long, a hammertoe develops. Ill-fitting shoes, arthritis, heredity, even an injury, can cause the hammertoe to form. To add insult to injury, corns and calluses are common on top of hammertoes because the toe is rubbing against the shoe.
Causes
Hammer toe results from shoes that don?t fit properly or a muscle imbalance, usually in combination with one or more other factors. Muscles work in pairs to straighten and bend the toes. If the toe is bent and held in one position long enough, the muscles tighten and cannot stretch out. Some other causes are diabetes, arthritis, neuromuscular disease, polio or trauma.

Symptoms include sharp pain in the middle of the toe and difficulty straightening the toe. People with hammertoe may also develop blisters, which are fluid-filled pockets of skin, because the bent toe is likely to rub against the inside of a shoe. This increased friction may also lead to calluses, which are areas of thickened skin, and corns, which are hard lumps that may form on or between toes. Symptoms may be minor at first, but they can worsen over time.
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
For hammertoes that are still flexible, a podiatrist might recommend padding or taping the toes to relieve pain and orthotic inserts for shoes to minimize pressure and keep the toe properly aligned. Anti-inflammatory drugs or corticosteroid injections can relieve pain and inflammation. For more advanced cases of hammertoe, a podiatrist might recommend a surgical procedure to cut the tendon, allowing the toe to straighten. For hammertoes that have become rigid, a more complicated surgery might be needed, during which the podiatrist removes part of the bone at the deformed joint to allow it to straighten.
Surgical Treatment
he basis for hammer toe surgery most often involves removing s portion of bone within Hammer toes the toe, to reduce the joint contracture. Depending on the direction the toe is deviated, soft tissue procedures may be necessary along with pinning the toe with a surgical wire.
