When a person has Hammer toes, the end of their toe bends downward and the middle joint curls up. Eventually, the toe gets stuck in a stiff, claw-like position. When the inside of your shoe rubs against a hammer toe, corns, blisters or calluses may form on top of the toe or on the bottom of your foot. This can make walking painful. You may also have pain in the joint where your big toe joins your foot. Hammer toe usually affects a person?s second toe (the toe next to the big toe), but it can affect other toes too.
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.

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
The exam may reveal a toe in which the near bone of the toe (proximal phalanx) is angled upward and the middle bone of the toe points in the opposite direction (plantar flexed). Toes may appear crooked or rotated. The involved joint may be painful when moved, or stiff. There may be areas of thickened skin (corns or calluses) on top of or between the toes, a callus may also be observed at the tip of the affected toe beneath the toenail. An attempt to passively correct the deformity will help elucidate the best treatment option as the examiner determines whether the toe is still flexible or not. It is advisable to assess palpable pulses, since their presence is associated with a good prognosis for healing after surgery. X-rays will demonstrate the contractures of the involved joints, as well as possible arthritic changes and bone enlargements (exostoses, spurs). X-rays of the involved foot are usually performed in a weight-bearing position.
Non Surgical Treatment
To keep your hammertoes more comfortable, start by replacing your tight, narrow, pointy shoes with those that have plenty of room in the toes. Skip the high heels in favor of low-heeled shoes to take the pressure off your toes. You should have at least one-half inch between your longest toe and the tip of your shoe. If you don't want to go out and buy new shoes, see if your local shoe repair shop can stretch your shoes to make the toe area more accommodating to your hammertoe.
Surgical Treatment
If a person's toes have become very inflexible and unresponsive to hammertoes non-invasive means of treatment and if open sores have developed as a result of constant friction, they may receive orthopaedic surgery to correct the deformity. The operation is quick and is commonly performed as an out-patient procedure. The doctor administers a local anesthetic into the person's foot to numb the site of the operation. The person may remain conscious as the surgeon performs the procedure. A sedative might also be administered to help calm the person if they are too anxious.
