Hammer Toe Complications

Overview

Hammer toes affects both joints of a toe, causing the toe to bend upwards at the proximal joint (the joint closest to the foot) and down at the distal joint (the one farthest away from the hammertoe foot). The resulting unnatural bend is often compared to an upside down "V" and also to a hammer or a claw (The condition is sometimes referred to as clawtoe or clawfoot). A similar condition, in which the first joint of a toe simply bends downward, is called mallet toe. Since the arched bending of hammertoe often causes the toe to rub against the top of the shoe's toe box and against the sole, painful corns and calluses develop on the toes. Hammertoe can also be a result of squeezing within a too-small or ill-fitting shoe or wearing high heels that jam your toes into a tight toe box inside your shoe, arthritis, trauma and muscle and nerve damage from diseases such as diabetes. Probably because of the tight-shoe and high-heel shoe factors, hammertoe tends to occur far more often in women than in men.

Causes

Hammer toe is often caused by wearing shoes that do not fit properly. If shoes are too small either in length or width, then the toes are held in a shortened position for long periods and the muscles eventually shorten and pull the toes into the bent position. Alternatively it can be caused by overactivity in the extensor digitorum dongus muscle (right) and a weakness in the counteracting muscle under the foot, such as flexor digitorum longus. Sometimes it can be a congenital condition, meaning it is present from birth. It is also more common in those with arthritis in the foot or diabetes.

Symptoms

A hammertoe causes you discomfort when you walk. It can also cause you pain when trying to stretch or move the affected toe or those around it. Hammertoe symptoms may be mild or severe. Mild Symptoms, a toe that is bent downward, corns or calluses. Severe Symptoms, difficulty walking, the inability to flex your foot or wiggle your toes, claw-like toes. See your doctor or podiatrist right away if you develop any of these symptoms.

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 If the deformed toe is very painful, your doctor may recommend that you have a fluid sample withdrawn from the joint with a needle so the fluid can be checked for signs of infection or gout (arthritis from crystal deposits).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

Treatment options for a hammertoe are based on the severity of the condition. A hammertoe caused by inappropriate footwear can be corrected by wearing properly fitting shoes. If a high arch caused the condition, wearing toe pads or insoles in your shoes can help. These pads work by shifting your toe?s position, which relieves pain and corrects the appearance of your toe.

Surgical Treatment

Surgery to correct for a hammertoe may be performed as a day procedure. There are several different types of procedures that can be used depending on the foot structure and if the deformity is flexible or rigid.
