Overview
A Hammertoe 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
The most common cause of hammertoe is a muscle/tendon imbalance. This imbalance, which leads to a bending of the toe, results from mechanical (structural) changes in the foot that occur over time in some people. Hammertoes may be aggravated by shoes that don?t fit properly. A hammertoe may result if a toe is too long and is forced into a cramped position when a tight shoe is worn. Occasionally, hammertoe is the result of an earlier trauma to the toe. In some people, hammertoes are inherited.

Symptoms
Hammertoe and mallet toe feature an abnormal bend in the joints of one or more of your toes. Moving the affected toe may be difficult or painful. Corns and calluses can result from the toe rubbing against the inside of your shoes. See your doctor if you have persistent foot pain that affects your ability to walk properly.

Diagnosis
Some questions your doctor may ask of you include, when did you first begin having foot problems? How much pain are your feet or toes causing you? Where is the pain located? What, if anything, seems to improve your symptoms? What, if anything, appears to worsen your symptoms? What kind of shoes do you normally wear? Your doctor can diagnose hammertoe or mallet toe by examining your foot. Your doctor may also order X-rays to further evaluate the bones and joints of your feet and toes.

Non Surgical Treatment
What will a doctor do? Treat any foot complaints such as corns, calluses by periodically reducing the lesion and applying appropriate pads and dressings. Recommend the silicone toe prop. If an infection is present, then anti-septic dressings, antibiotics and pads to redistribute pressure away from the lesion may be necessary. In the case of a mallet toe, trigger toe or claw toe. If a corn occurs at the end of the toe, a silicone or leather prop may be used to straighten the toe. In a hammertoe deformity, a silicone prop to redistribute pressure away from a corn may be necessary. The doctor may give footwear advice. In severe cases, corrective surgery may be necessary. The doctor may recommend orthosis to correct a mechanical complaint of the foot, such as 3/4 length silicone insoles.

Surgical Treatment
Joint resection procedures involves removing part of one of the two small joints of the toe directly underneath where the digit is crooked. The purpose is to make room for the toe to be re-positioned flat or straight. Because hammer toes become rigid or fixed with time, removing the joint becomes the only option when the knuckle is stiff. Its important to understand that this procedure does not involve the joint of the ball of the foot, rather the a small joint of the toe. Medical terminology for this procedure is called a proximal interphalangeal joint arthroplasty or a distal interphalangeal joint arthroplasty, with the latter involving the joint closer to the tip of the toe.
