OverviewHammertoe is foot deformity that typically affects second, third or fourth toes. The condition is called hammertoe because of the unnatural position your toes form. Hammertoe causes your toe to bend upward at the middle joint in a way that looks similar to a hammer. While it may not be painful at first, this condition usually worsens with time and it becomes difficult to extend your toes. Sometimes, calluses or corns form in association with hammertoe.
Causes
Though hammer toes are principally hereditary, several other factors can contribute to the deformity. Most prevalent is an imbalance of the muscles and tendons that control the motion of the toe. When the tendon that pulls the toe upward is not as strong as the one that pulls it downward there is a disparity of power. This forces the toe to buckle and gradually become deformed. If the it persists, the toe can become rigid and harder to correct.
Symptoms
The most common symptoms of hammertoes include. The toe is bent upward at the middle toe joint, so that the top of this joint rubs against the top of the shoe. The remainder of the toe is bent downward. Pain upon pressure at the top of the bent toe from footwear. The formation of corns on the top of the joint. Redness and swelling at the joint contracture. Restricted or painful motion of the toe joint. Pain in the ball of the foot at the base of the affected toe. This occurs because the contracted digit puts pressure on the metatarsal head creating callouse and pressure on the ball of the foot.
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
Treatment for a hammertoe usually depends on the stage of the hammertoe and the cause of the condition. If your toe is still bendable, your doctor may suggest conservative care-relieving pressure with padding and strapping, or proper shoes that have a deep toe box and are of adequate length and width. Early intervention can often prevent the need for surgery.
Surgical Treatment
There are generally two methods surgeons use to correct hammer toes, they are joint resection (arthroplasty) or bone mending (fusion), and the location where this is performed on the toe depends on where the toe is buckled. Its important to recognize that most of the surgical work involved the joints of the toe, not the joint of the ball of the foot. Sometimes a toe relocation procedure is needed when the joint of the ball of the foot is malaligned (subluxed or dislocated).
Prevention
Early Development. The first year of life is important for foot development. Parents should cover their babies' feet loosely, allowing plenty of opportunity for kicking and exercise. Change the child's position frequently. Children generally start to walk at 10 - 18 months. They should not be forced to start walking early. Wearing just socks or going barefoot indoors helps the foot develop normally and strongly and allows the toes to grasp. Going barefoot outside, however, increases the risk for injury and other conditions, such as plantar warts. Children should wear shoes that are light and flexible, and since their feet tend to perspire, their shoes should be made of materials that breathe. Replace footwear every few months as the child's feet grow. Footwear should never be handed down. Protect children's feet if they participate in high-impact sports.
