Overview
A Hammer Toe is a contracture of the toes as a result of a muscle imbalance between the tendons on the top and the tendons on the bottom of the toe. They can be flexible or rigid in nature. When they are rigid, it is not possible to straighten the toe out by manipulating it. Frequently, they develop corns on the top of the toe as a result of rubbing on the shoe. They may also cause a bothersome callous on the ball of the foot. This occurs as a result of the toe pressing downward on the bone behind the toe. This area then becomes prominent and the pressure of the bone against the ground causes a callous to form.

Causes
Footwear can contribute significantly to the development of hammertoes. Shoes that are too small force your toes into a curled position. Over time, your toe tendons adjust to this positioning, causing your toe or toes to hold a hammered shape. Athletes may be especially susceptible, because of the increased forces on the toes from shoes that are too small or tight. Heel elevation in footwear is also problematic, as it causes your toes to be pushed into the shoe?s toe box. Heel elevation additionally contributes to muscle imbalance. A common example of this is when your Achilles tendon-the tendon at the back of your leg that attaches your calf muscles to your heel bone-is too tight, causing the tendons on the top of your foot that attach to your toes to work too hard and hold your toes in an unnatural, elevated position.

Symptoms
Common symptoms of hammertoes include pain or irritation of the affected toe when wearing shoes. corns and calluses (a buildup of skin) on the toe, between two toes, or on the ball of the foot. Corns are caused by constant friction against the shoe. They may be soft or hard, depending upon their location. Inflammation, redness, or a burning sensation. Contracture of the toe. In more severe cases of hammertoe, open sores may form.

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
Your podiatrist may recommend one or more of these treatments to manage your hammer toes. Wear shoes with roomy toe boxes which don?t force your toes together. Exercises to stretch and strengthen muscles in the toes. Over the counter toe straps, cushions, and corn pads. Custom orthotic inserts. Toe caps or toe slings. In severe cases, surgery to release the muscles in the affected toes.

Surgical Treatment
Surgical correction is necessary in more severe cases and may consist of removing a bone spur (exostectomy) removing the enlarged bone and straightening the toe (arthroplasty), sometimes with internal fixation using a pin to realign the toe; shortening a long metatarsal bone (osteotomy) fusing the toe joint and then straightening the toe (arthrodesis) or simple tendon lengthening and capsule release in milder, flexible hammertoes (tenotomy and capsulotomy). The procedure chosen depends in part on how flexible the hammertoe is.
