Overview
Uneven muscle tension results in the distortion of one or several of the small toes. (Hammertoe) Pressure points develop at the raised middle joint as well as at the tip of the toe and underneath the metatarsal head. In the beginning, when the misalignment can still be corrected, it often suffices to lengthen the tendon and to cut a notch into the capsule. In a contracted misalignment, part of the middle joint is removed to form a replacement joint. Modern surgical techniques preserve the metatarsophalangeal joint (Weil or Helal osteotomies).

Causes
Though hammer toes are principally hereditary, several other factors can contribute to the deformity. Most prevalent is an imbalance of the muscles and tendons that control the motion of the toe. When the tendon that pulls the toe upward is not as strong as the one that pulls it downward there is a disparity of power. This forces the toe to buckle and gradually become deformed. If the it persists, the toe can become rigid and harder to correct.

Symptoms
Some people never have troubles with hammer toes. In fact, some people don't even know they have them. They can become uncomfortable, especially while wearing shoes. Many people who develop symptoms with hammer toes will develop corns, blisters and pain on the top of the toe, where it rubs against the shoe or between the toes, where it rubs against the adjacent toe. You can also develop calluses on the balls of the feet, as well as cramping, aching and an overall fatigue in the foot and leg.

Diagnosis
Your doctor is very likely to be able to diagnose your hammertoe simply by examining your foot. Even before that, he or she will probably ask about your family and personal medical history and evaluate your gait as you walk and the types of shoes you wear. You'll be asked about your symptoms, when they started and when they occur. You may also be asked to flex your toe so that your doctor can get an idea of your range of motion. He or she may order x-rays in order to better define your deformity.

Non Surgical Treatment
In many cases, conservative treatment consisting of physical therapy and new shoes with soft, spacious toe boxes is enough to resolve the condition, while in more severe or longstanding cases podiatric surgery may be necessary to correct the deformity. The patient's doctor may also prescribe some toe exercises that can be done at home to stretch and strengthen the muscles. For example, the individual can gently stretch the toes manually, or use the toes to pick things up off the floor. While watching television or reading, one can put a towel flat under the feet and use the toes to crumple it. The doctor can also prescribe a brace that pushes down on the toes to force them to stretch out their muscles.

Surgical Treatment
Surgery is used when other types of treatment fail to relieve symptoms or for advanced cases of hammertoe. There are several types of surgeries to treat hammertoe. A small piece of bone may be removed from the joint (arthroplasty). The toe joint may be fused to straighten it (arthrodesis). Surgical hardware, such as a pin, may be used to hold the bones in place while they heal. Other types of surgery involve removing skin (wedging) or correcting muscles and tendons to balance the joint.

Prevention
There are several things you can do to help prevent hammer toes from forming or progressing. Wear supportive shoes to help prevent deformities. Hammer toes are often related to faulty foot mechanics, especially foot flattening. Wear custom orthotics prescribed by your podiatrist. Orthotics may slow the progression or prevent the development of hammer toes. Avoid shoes with narrow or pointed toe boxes that can compress the toes.
