What Causes Hammertoe Deformity

Hammer ToeOverview

Hammer, mallet, and claw toes have distinctive differences that can assist you in determining what kind of toe problem you are dealing with. All three conditions deal with toes that are curved into abnormal positions, which possibly look strange and may cause pain. Typically, the big toe is not affected by these problems. A Hammer toe tends to bend downward at the center of a toe joint. It generally affects your second toe. The affliction causes the center of your toe to rise and is often accompanied with a bony lump.

Causes

Hammertoe commonly develops because of structural changes that take place over time in the muscles and tendons that bend the toes. People with certain medical conditions, such as diabetes, are at risk for developing hammertoe. It can be an inherited condition for some people. Other causes include trauma and wearing shoes that are too tight, narrow, or have high heels. The toe next to the big toe (second toe) is most frequently affected by hammertoe.

HammertoeSymptoms

Hammer toes can cause problems with walking and lead to other foot problems, such as blisters, calluses, and sores. Pain is caused by constant friction over the top of the toe?s main joint. It may be difficult to fit into some shoe gear due to the extra space required for the deformed toe. In many cases there will be pain on the ball of the foot over the metatarsals along with callus formation. This is due to the toes not functioning properly, failing to properly touch the ground during the gait cycle. The ball of the foot then takes the brunt of the ground forces, which causes chronic pain.

Diagnosis

The exam may reveal a toe in which the near bone of the toe (proximal phalanx) is angled upward and the middle bone of the toe points in the opposite direction (plantar flexed). Toes may appear crooked or rotated. The involved joint may be painful when moved, or stiff. There may be areas of thickened skin (corns or calluses) on top of or between the toes, a callus may also be observed at the tip of the affected toe beneath the toenail. An attempt to passively correct the deformity will help elucidate the best treatment option as the examiner determines whether the toe is still flexible or not. It is advisable to assess palpable pulses, since their presence is associated with a good prognosis for healing after surgery. X-rays will demonstrate the contractures of the involved joints, as well as possible arthritic changes and bone enlargements (exostoses, spurs). X-rays of the involved foot are usually performed in a weight-bearing position.

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

For the surgical correction of a rigid hammertoe, the surgical procedure consists of removing the damaged skin where the corn is located. Then a small section of bone is removed at the level of the rigid joint. The sutures remain hammertoe in place for approximately ten days. During this period of time it is important to keep the area dry. Most surgeons prefer to leave the bandage in place until the patient's follow-up visit, so there is no need for the patient to change the bandages at home. The patient is returned to a stiff-soled walking shoe in about two weeks. It is important to try and stay off the foot as much as possible during this time. Excessive swelling of the toe is the most common patient complaint. In severe cases of hammertoe deformity a pin may be required to hold the toe in place and the surgeon may elect to fuse the bones in the toe. This requires several weeks of recovery.
