OverviewHammer toes is the general term used to describe an abnormal contraction or "buckling" of the toe because of a partial or complete dislocation of one of the joints of the toe or the joint where the toe joins with the rest of the foot. As the toe becomes deformed, it rubs against the shoe and the irritation causes the body to build up more and thicker skin to help protect the area. The common name for the thicker skin is a corn.
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
The symptoms of a hammer toe are usually first noticed when a corn develops on the top of the toe and becomes painful, usually when wearing tight shoes. There may be a bursa under the corn or instead of a corn, depending on the pressure. Most of the symptoms are due to pressure from footwear on the toe. There may be a callus under the metatarsal head at the base of the toe. Initially a hammer toe is usually flexible, but when longstanding it becomes more rigid.
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 your toe is still flexible, your doctor may recommend that you change to roomier and more comfortable footwear and that you wear shoe inserts (orthotics) or pads. Wearing inserts or pads can reposition your toe and relieve pressure and pain. In addition, your doctor may suggest exercises to stretch and strengthen your toe muscles. These may include picking up marbles or a thin towel off the floor with your toes.
Surgical Treatment
The deformity is corrected in a variety of ways. There are actually a large number of procedures. The simplest procedure would involve a Tenotomy, the cutting of the tendon causing the deformity or a Tendon Lengthening procedure. These procedures are infrequently done, though, as the structural deformity (the arthritis and joint adaptation) is not addressed with these surgeries. Other soft-tissue procedures involve rebalancing the tendons around the joint. There are several techniques to do this, but the most common is probably the Girdlestone-Taylor procedure, which involves rerouting the tendons on the bottom of the toe up and over the toe where it sticks up, so that the tendon helps pull the toe downwards into proper alignment.
