OverviewHammertoe (hammertoe) is a deformity of the second, third, or fourth toes. In this condition, the toe is bent at the middle joint, into an upward position, causing it to resemble a hammer (sometimes decribed as ?curled toes?). Left untreated, hammer toes can become inflexible and require surgery. Toes which take on a curled appearance are hammer toes. Mallet toe is a similar condition, but affects the upper joint of a toe.
Causes
Risk factors for hammertoe include heredity, a second toe that is longer than the first (Morton foot), high arches or flat feet, injury in which the toe was jammed, rheumatoid arthritis, and, in diabetics, abnormal foot mechanics resulting from muscle and nerve damage. Hammertoe may be precipitated by advancing age, weakness of small muscles in the foot (foot intrinsic muscles), and the wearing of shoes that crowd the toes (too tight, too short, or with heels that are too high). The condition is more common in females than in males.
Symptoms
The middle joint of the toe is bent. The end part of the toe bends down into a claw-like deformity. At first, you may be able to move and straighten the toe. Over time, you will no longer be able to move the toe. It will be painful. A corn often forms on the top of the toe. A callus is found on the sole of the foot. Walking or wearing shoes can be painful.
Diagnosis
Although hammertoes are readily apparent, to arrive at a diagnosis the foot and ankle surgeon will obtain a thorough history of your symptoms and examine your foot. During the physical examination, the doctor may attempt to reproduce your symptoms by manipulating your foot and will study the contractures of the toes. In addition, the foot and ankle surgeon may take x-rays to determine the degree of the deformities and assess any changes that may have occurred.
Non Surgical Treatment
If your hammertoe problem is diagnosed as flexible hammertoe, there are a number of nonsurgical treatments that may be able to straighten out your toe or toes and return them to their proper alignment. Padding and Taping. Your physician may pad the boney top-part of your hammertoe as a means of relieving pain, and may tape your toes as a way to change their position, correct the muscle imbalance and relieve the pressure that led to the hammertoe's development. Medication. Anti-inflammatory drugs such as aspirin and ibuprofen can help deal with inflammation, swelling and pain caused by your hammertoe. Cortisone injections may be prescribed for the same purpose. If your hammertoe is a consequence of arthritis, your physician may prescribe medications for that.
Surgical Treatment
If conservative treatments fail and your symptoms persist, the doctor may recommend a surgical option to straighten the toe. The procedures used vary greatly, depending upon the reasons for the hammertoe. There are a number of different operations to correct hammertoes, the most common ones involve Soft tissue corrections such as tendon transfers, tendon lengthening, and joint capsule repairs. Digital arthroplasty involves removal of bone from the bent joint to allow the toe to straighten. The temporary use of pins or K-wires may be necessary to keep the toe straight during the healing period. Joint implants are sometimes used to allow for a better range of motion in the toe following surgery. Digital arthrodesis involves the removal of bone from the bent joint and fusing the toe in a straight position. If the corn is due to a bone spur, the most common procedure used is an exostectomy, in which surgically removing it or filing it down removes the bone spur. Because of the possible complications involved with any surgery, one should be sure to understand the risks that may be involved with surgery to correct hammertoes and remove bone spurs.
Prevention
As long as hammertoe causes no pain or any change in your walking or running gait, it isn?t harmful and doesn't require treatment. The key to prevention is to wear shoes that fit you properly and provide plenty of room for your toes.
