OverviewA Hammertoe is a toe that is bent because of a weakened muscle. The weakened muscle makes the tendons (tissues that connect muscles to bone) shorter, causing the toes to curl under the feet. Hammertoes can run in families. They can also be caused by shoes that are too short. Hammertoes can cause problems with walking and can lead to other foot problems, such as blisters, calluses, and sores. Splinting and corrective footwear can help in treating hammertoes. In severe cases, surgery to straighten the toe may be necessary.
Causes
Hammer toe usually affects the second toe. However, it may also affect the other toes. The toe moves into a claw-like position. The most common cause of hammer toe is wearing short, narrow shoes that are too tight. The toe is forced into a bent position. Muscles and tendons in the toe tighten and become shorter. Hammer toe is more likely to occur in women who wear shoes that do not fit well or have high heels and children who keep wearing shoes they have outgrown. The condition may be present at birth (congenital) or develop over time. In rare cases, all of the toes are affected. This may be caused by a problem with the nerves or spinal cord.
Symptoms
Symptoms include sharp pain in the middle of the toe and difficulty straightening the toe. People with hammertoe may also develop blisters, which are fluid-filled pockets of skin, because the bent toe is likely to rub against the inside of a shoe. This increased friction may also lead to calluses, which are areas of thickened skin, and corns, which are hard lumps that may form on or between toes. Symptoms may be minor at first, but they can worsen over time.
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 If the deformed toe is very painful, your doctor may recommend that you have a fluid sample withdrawn from the joint with a needle so the fluid can be checked for signs of infection or gout (arthritis from crystal deposits).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
Early on, when a hammertoe first starts and is still flexible, here are some ways it might be treated. Your healthcare provider may splint or tape the toe into the correct, normal position. You can use your fingers to stretch your toes and toe joints toward a more normal position. Exercise your toes by trying to pick up marbles with them or by wadding up a towel on the floor with your toes. Padding may be used to change where your weight falls when you walk on the foot.
Surgical Treatment
Sometimes when the joints are removed the two bones become one as they are fused in a straightened position. Many times one toe will be longer than another and a piece of bone is removed to bring the toes in a more normal length in relation to each other. Sometimes tendons will be lengthened, or soft tissue around the joints will be cut or rebalanced to fix the deformity. Angular corrections may also be needed. The surgeon may place fixation in your foot as it heals which may include a pin, or wires.
