OverviewA Hammer Toe is a contracture, or bending, of the toe at the first joint of the digit, called the proximal interphalangeal joint. This bending causes the toe to appear like an upside-down V when looked at from the side. Any toe can be involved, but the condition usually affects the second through fifth toes, known as the lesser digits. Hammer toes are more common in females than males.
Causes
Hammer toe usually affects the second toe. However, it may also affect the other toes. The toe moves into a claw-like position. The most common cause of hammer toe is wearing short, narrow shoes that are too tight. The toe is forced into a bent position. Muscles and tendons in the toe tighten and become shorter. Hammer toe is more likely to occur in women who wear shoes that do not fit well or have high heels and children who keep wearing shoes they have outgrown. The condition may be present at birth (congenital) or develop over time. In rare cases, all of the toes are affected. This may be caused by a problem with the nerves or spinal cord.
Symptoms
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
Changing the type of footwear worn is a very important step in the treatment of hammer toes. When choosing a shoe, make sure the toe box (toe area) is high and broad, and can accommodate the hammer toes. A shoe with a high, broad toe box will provide enough room in the forefoot area so that there is less friction against the toes. Other conservative treatments include using forefoot products designed to relieve hammer toes, such as hammer toe crests and hammer toe splints. These devices will help hold down the hammer toe and provide relief to the forefoot. Gel toe shields and gel toe caps are also recommended to eliminate friction between the shoe and the toe, while providing comfort and lubrication.
Surgical Treatment
Surgery to straighten the toe may be needed if an ulcer has formed on either the end or the top surface of the toe. Surgery sometimes involves cutting the tendons that support movement in the toe so that the toe can be straightened. Cutting the tendons, however, takes away the ability to bend the very end of the toe. Another type of surgery combines temporary insertion of a pin or rod into the toe and alteration or repair of the tendons, so that the toe is straightened. After surgery, the deformity rarely recurs.
