Hammer toe 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.
As described above, the main reason people develop hammertoes is improper footwear, or footwear that is too short for the toes. Shoes that do not allow our toes to lie flat are the biggest cause of hammertoes, though there are others, including genetics, injury or trauma in which the toe is jammed or broken. Diseases that affect the nerves and muscles, such as arthritis. Abnormal foot mechanics due to nerve or muscle damage, causing an imbalance of the flexor and extensor tendons of the toe. Systematic diseases such as arthritis can also lead to problems such as hammertoe. Some people are born with hammertoes, while others are more prone to developing the condition due to genetics. If you have ever broken a toe, you know there is not much that can be done for it. It is one of the only bones in the body that heals without the use of a cast. A broken toe may be splinted, however, which may help prevent a hammertoe from forming.
The symptoms of hammertoe include a curling toe, pain or discomfort in the toes and ball of the foot or the front of the leg, especially when toes are stretched downward. Thickening of the skin above or below the affected toe with the formation of corns or calluses. Difficulty finding shoes that fit well. In its early stages, hammertoe is not obvious. Frequently, hammertoe does not cause any symptoms except for the claw-like toe shape.
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 If the deformed toe is very painful, your doctor may recommend that you have a fluid sample withdrawn from the joint with a needle so the fluid can be checked for signs hammertoes of infection or gout (arthritis from crystal deposits).
Non Surgical Treatment
In the earlier stages of hammer toe, when the toes can still be manually straightened, then conservative treatment is appropriate. This means wearing shoes which are a half size bigger than normal and which are not narrow around the toes. Exercises to stretch the toes out and strengthen the muscles under the foot which balances the tightness of the top tendons are important. Padding or corn plasters can be used to ease the discomfort of any associated corns and calluses.
In advanced cases in which the toe has become stiff and permanently bent, the toe can be straightened with surgery. One type of surgery involves removing a small section of the toe bone to allow the toe to lie flat. Surgery for hammertoe usually is classified as a cosmetic procedure. Cosmetic foot surgeries sometimes result in complications such as pain or numbness, so it’s better to treat the problem with a shoe that fits properly.
