Overview
Hammer toes is a Z-shaped deformity caused by dorsal subluxation at the metatarsophalangeal joint. Diagnosis is clinical. Treatment is modification of footwear and/or orthotics. The usual cause is misalignment of the joint surfaces due to a genetic predisposition toward aberrant foot biomechanics and tendon contractures. RA and neurologic disorders such as Charcot-Marie-Tooth disease are other causes.
Causes
Wearing shoes that squeeze the toes or high heels that jam the toes into the front of the shoe. Other causes or factors in the development of hammertoes can include an injury such as badly stubbing your toe, arthritis and nerve and muscle damage from diseases such as diabetes. And, hammertoes tend to run in families, although it is more likely the faulty foot mechanics that lead to hammertoes that are inherited, not the hammertoes themselves. Hammertoe generally affect the smaller toes of the foot, especially the second toe, which for many people is the longest toe. It’s uncommon for the big toe to be bent this way.
Symptoms
The symptoms of a hammer toe include the following. Pain at the top of the bent toe upon pressure from footwear. Formation of corns on the top of the joint. Redness and swelling at the joint contracture. Restricted or painful motion of the toe joint. Pain in the ball of the foot at the base of the affected toe.
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. If the deformed toe is very painful, your doctor may recommend that you have a fluid sample withdrawn from the joint with a needle so the fluid can be checked for signs of infection or gout (arthritis from crystal deposits).
Non Surgical Treatment
Conservative treatment starts with new shoes that have soft, roomy toe boxes. Shoes should be one-half inch longer than your longest toe. For many people, the second toe is longer than the big toe.) Avoid wearing tight, narrow, high-heeled shoes. You may also be able to find a shoe with a deep toe box that accommodates the hammer toe. Or, a shoe repair shop may be able to stretch the toe box so that it bulges out around the toe. Sandals may help, as long as they do not pinch or rub other areas of the foot.
Surgical Treatment
There are generally two methods surgeons use to correct hammer toes, they are joint resection (arthroplasty) or bone mending (fusion), and the location where this is performed on the toe depends on where the toe is buckled. Its important to recognize that most of the surgical work involved the joints of the toe, not the joint of the ball of the foot. Sometimes a toe relocation procedure is needed when the joint of the ball of the foot is malaligned (subluxed or dislocated).
Prevention
If you notice the beginning signs of hammertoe, you may be able to prevent the tendons from tightening by wearing toe-friendly shoes, by flattening your toes regularly, and by soaking your feet every day in warm water, then stretching your toes and ankles by pointing your toes. Foot exercises also can help to maintain or restore the flexibility of the tendons. One simple Hammer toe exercise is to place a small towel on the floor and then pick it up using only your toes. You also can grasp at carpet with your toes or curl your toes up and down repeatedly.
