Overview
Hammertoes, also called hammer toe, deformity of the second, third, or fourth toe in which the toe is bent downward at the middle joint (the proximal interphalangeal [PIP] joint), such that the overall shape of the toe resembles a hammer. Most cases of hammertoe involve the second toe, and often only one or two toes are affected. In rare cases when all the toes are involved, a thorough neurological assessment is necessary to evaluate for underlying nerve or spinal cord problems.

Causes
Hammer toe is often caused by wearing shoes that do not fit properly. If shoes are too small either in length or width, then the toes are held in a shortened position for long periods and the muscles eventually shorten and pull the toes into the bent position. Alternatively it can be caused by overactivity in the extensor digitorum dongus muscle (right) and a weakness in the counteracting muscle under the foot, such as flexor digitorum longus. Sometimes it can be a congenital condition, meaning it is present from birth. It is also more common in those with arthritis in the foot or diabetes.

Symptoms
Signs and symptoms of hammertoe and mallet toe may include a hammer-like or claw-like appearance of a toe. In mallet toe, a deformity at the end of the toe, giving the toe a mallet-like appearance. Pain and difficulty moving the toe. Corns and calluses resulting from the toe rubbing against the inside of your footwear. Both hammertoe and mallet toe can cause pain with walking and other foot movements.

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
Symptomatic treatment of hammertoes consists of such things as open toed shoes or hammertoe pads. There are over the counter corn removers for temporally reducing the painful callous often seen with the hammertoe. These medications must be used with caution. They are a mild acid that burns the callous off. These medications should never be used for corns or callouses between the toes. Persons with diabetes or bad circulation should never use these products.

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.

Prevention
To help prevent hammer toes from developing, wear shoes or boots that provide sufficient width in the toe box to ensure minimal compression. Use inserts that help the toes flatten out and spread and give sufficient support to the metatarsal arch in the forefoot. If hammer toes have already formed, padded socks help protect the tops and the tips of the hammer toes and may reduce pain from rubbing and chafing.
