When there?s an imbalance in the muscle and ligament surrounding a toe joint, the effect is a bend in the middle joint of the toe, which causes the whole toe to bend upward. Because the toe is bent in an unnatural way, it?s common for the toe to become irritated and even develop corns. A toe that curls under rather than bends upward is also considered a Hammer toe.
Hammer toe results 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.
People with a hammer toe will often find that a corn or callus will develop on the top of the toe, where it rubs against the top of the footwear. This can be painful when pressure is applied or when anything rubs on it. The affected joint may also be painful and appear swollen.
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
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.
Until recently, wires were used for surgical correction. In this technique, one or more wires are inserted into the bone through both the affected joint and a normally healthy toe joint, and the end of the toe. These wires stay in place for four to six weeks, protruding from the end of the toes. Due to the protruding wire, simple things such working, driving, bathing and even sleeping are difficult while these wires are in place. During this recovery period, patients often experience discomfort during sleep and are subject possible infection.
Although there is little doubt shoes are responsible for causing corns, the size, shape and Hammer toes other characteristics of our feet are hereditary. A severe bunion may cause a hammertoe, as the great toe twists over or under the second toe, causing it to dislocate.
