A hammer toe deformity is a contracture of the toe(s). In this condition, the toe is bent at the middle joint, so that it is buckled or hammered. Initially, hammer toes are flexible and can be corrected with simple measures but, if left untreated, they can become fixed and require surgery.

People with hammer toes may have corns or calluses on the top of the middle joint of the toe or on the tip of the toe. They may also feel pain in their toes or feet and have difficulty finding comfortable shoes.

Causes of hammer toes
Hammer toes result from shoes that don’t fit properly or a muscle imbalance, usually in combination with one or more other factors. Muscles work in pairs to straighten and bend the toes. If the toe is bent and held in one position long enough, the muscles tighten and cannot stretch out. Shoes that narrow toward the toe may make your forefoot look smaller. But they also push the smaller toes into a flexed (bent) position. The toes rub against the shoe, leading to the formation of corns and calluses, which further aggravate the condition. A higher heel forces the foot down and squishes the toes against the shoe, increasing the pressure and the bend in the toe. Eventually, the toe muscles become unable to straighten the toe, even when there is no confining shoe.

Treatment for hammer toes
Conservative treatment starts with new shoes that have soft, roomy toe boxes. Shoes should be one-half inch longer than your longest toe. (Note: 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.

Your doctor may recommend that you use commercially available straps, cushions or nonmedicated corn pads to relieve symptoms. You should try to avoid all medicated corn pads as they usually do more harm than good. If you have diabetes, poor circulation or a lack of feeling in your feet, avoid any forms of self-treatment and visit a podiatrist..

Hammer toes can be corrected by surgery if conservative measures fail. Usually, surgery is done on an outpatient basis with a local anesthetic. The actual procedure will depend on the type and extent of the deformity. After the surgery, there may be some stiffness, swelling and redness and the toe may be slightly longer or shorter than before. You will be able to walk, but should not plan any long hikes while the toe heals, and should keep your foot elevated as much as possible.
