Overview
A Hammer Toe is a deformity of the second, third or fourth toes. In this condition, the toe is bent at the middle joint, so that it resembles a hammer. Initially, hammer toes are flexible and can be corrected with simple measures but, if left untreated, they can become fixed and require surgery. People with hammer toe may have corns or calluses on the top of the middle joint of the toe or on the tip of the toe. They may also feel pain in their toes or feet and have difficulty finding comfortable shoes.

Causes
Risk factors for hammertoe include heredity, a second toe that is longer than the first (Morton foot), high arches or flat feet, injury in which the toe was jammed, rheumatoid arthritis, and, in diabetics, abnormal foot mechanics resulting from muscle and nerve damage. Hammertoe may be precipitated by advancing age, weakness of small muscles in the foot (foot intrinsic muscles), and the wearing of shoes that crowd the toes (too tight, too short, or with heels that are too high). The condition is more common in females than in males.

Symptoms
Hammer toes can cause problems with walking and lead to other foot problems, such as blisters, calluses, and sores. Pain is caused by constant friction over the top of the toe?s main joint. It may be difficult to fit into some shoe gear due to the extra space required for the deformed toe. In many cases there will be pain on the ball of the foot over the metatarsals along with callus formation. This is due to the toes not functioning properly, failing to properly touch the ground during the gait cycle. The ball of the foot then takes the brunt of the ground forces, which causes chronic pain.

Diagnosis
A hammertoe is usually diagnosed with a physical inspection of your toe. Imaging tests, such as X-rays, may be ordered if you have had a bone, muscle, or ligament injury in your toe.

Non Surgical Treatment
Early on, when a hammertoe first starts and is still flexible, here are some ways it might be treated. Your healthcare provider may splint or tape the toe into the correct, normal position. You can use your fingers to stretch your toes and toe joints toward a more normal position. Exercise your toes by trying to pick up marbles with them or by wadding up a towel on the floor with your toes. Padding may be used to change where your weight falls when you walk on the foot.

Surgical Treatment
There are several surgical techniques used to treat hammertoes. When the problem is less severe, the doctor will remove a small piece of bone at the involved joint and realign the toe joint. More severe hammer toes may need more complicated surgery.
