Overview
Hammertoe is caused when the middle joint (PIP) bends down towards the floor (flexion). To compensate, the joints above and below (MTP, DIP) bend up (hyperextend). The result is that the middle part of the toe lifts up. Hammertoe is the most common deformity of the lesser toes (i.e. not the big toe). It tends to only affect one toe, most commonly the second.

Causes
Claw, hammer and mallet toe are most commonly caused by wearing high heels or ill-fitting shoes that are too tight e.g. narrow toebox. If shoes like this are worn for long periods, the foot is held in a slightly bent position and gradually over time, the muscles tighten and shorten. If this continues for long enough, then the muscles become so tight that even when shoes are removed, the toe is still held in the bent position. Another common cause is Morton?s Toe, where the second toe is longer than the big toe. In this case, the second toe is commonly squashed into a shoe into an unnaturally bent position.

Symptoms
Patients with hammer toe(s) may develop pain on the top of the toe(s), tip of the toe, and/or on the ball of the foot. Excessive pressure from shoes may result in the formation of a hardened portion of skin (corn or callus) on the knuckle and/or ball of the foot. Some people may not recognize that they have a hammer toe, rather they identity the excess skin build-up of a corn.The toe(s) may become irritated, red, warm, and/or swollen. The pain may be dull and mild or severe and sharp. Pain is often made worse by shoes, especially shoes that crowd the toes. While some hammer toes may result in significant pain, others may not be painful at all. Painful toes can prevent you from wearing stylish shoes.

Diagnosis
Most health care professionals can diagnose hammertoe simply by examining your toes and feet. X-rays of the feet are not needed to diagnose hammertoe, but they may be useful to look for signs of some types of arthritis (such as rheumatoid arthritis) or other disorders that can cause hammertoe.

Non Surgical Treatment
If you have hammer toe, avoiding tight shoes and high heels may provide relief. Initial (non-surgical) treatment for hammer toe involves wearing shoes with plenty of room in the toe area. Shoes should be at least one-half inch longer than the longest toe. Stretching and strengthening exercises for the toes (such as picking up items with the toes or stretching the toes by hand) are also recommended. Sometimes orthopedists recommend special pads, cushions, or slings to help relieve the pain of hammer toe.

Surgical Treatment
Several surgical procedures are available to the podiatric physician. For less severe deformities, the surgery will remove the bony prominence and restore normal alignment of the toe joint, thus relieving pain. Severe hammertoes, which are not fully reducible, may require more complex surgical procedures. Recuperation takes time, and some swelling and discomfort are common for several weeks following surgery. Any pain, however, is easily managed with medications prescribed by your podiatric physician.

Prevention
The best treatment is good prevention! Hammertoe can be prevented by wearing shoes with ample toe room, avoiding high heels, and wearing adjustable shoes to assure a looser fit. When buying shoes, shop at the end of the day when your feet are swollen from daily activity, try both shoes on to confirm they fit properly, and if necessary, visit a shoe repair store to see if they can stretch your shoes for a better fit.
