Hammer Toe Surgery Procedure

Overview

A Hammer toes is a deformity of the middle joint of a toe, producing a clenched, clawlike appearance in the affected digit. The tendons in the toe become abnormally contracted, causing the toe to bend downward, which, in turn, forces the joint to protrude upward. A mallet toe is a deformity in which the end joint of a toe becomes bent downward, so that the toe curls underneath itself. In either case the affected joints are stiff, and often the toe cannot be straightened out. Constant rubbing against shoes may furthermore cause a painful corn (a round patch of rough, thickened, calloused skin) to develop over the joint or at the tip of the affected toe. Hammer and mallet toes may occur in any toe, although the second toe is the most common site. These deformities are often painful and limit the toe?s range of motion-sometimes requiring surgery.

Causes

A person may be born with hammer toe or may develop it from wearing short, narrow shoes. Hammer toe can occur in children who outgrow shoes rapidly. Sometimes hammer toe is genetic and is caused by a nerve disorder in the foot. High heeled shoes are can also cause hammer toe. The reason for this is that the toes are not only bunched up, but the weight of the body is pushing them forward even further.

Symptoms

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.

Diagnosis

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

There are many non-surgical treatments to help relieve symptoms of hammertoe. The first step for many people is wearing the right size and type of shoe. Low-heeled shoes with a boxy or roomy toe area are helpful. Cushioned insoles, customized orthopedic inserts, and pads can provided relief as well. Splints or straps may be used to help correct toe position. Your doctor may show you toe stretches and exercises to perform. Your doctor can safely remove corns and calluses. You should not try to remove them at home.

Surgical Treatment

Probably the most frequent procedure performed is one called a Post or an Arthroplasty. In this case a small piece of bone is removed from the joint to straighten the toe. The toe is shortened somewhat, but there is still motion within the toe post-operatively. In other cases, an Arthrodesis is performed. This involves fusing the abnormally-contracted joint. The Taylor procedure fuses only the first joint in the toe, whereas the Lambrinudi procedure fuses both joints within the toe. Toes which have had these procedures are usually perfectly straight, but they take longer to heal and don’t bend afterwards. A Hibbs procedure is a transfer of the toe’s long extensor tendon to the top of the metatarsal bone. The idea of this procedure is to remove the deforming cause of the hammertoes (in this case, extensor substitution), but to preserve the tendon’s function in dorsifexing the foot by reattaching it to the metatarsals. Fortunately, the Gotch (or Gotch and Kreuz) procedure–the removal of the base of the toe where it attaches to the foot, is done less frequently than in years past. The problem with this procedure is that it doesn’t address the problem at the level of the deformity, and it causes the toe to become destabilized, often resulting in a toe that has contracted up and back onto the top of the foot. You can even have an Implant Arthroplasty procedure, where a small, false joint is inserted into place. There hammertoe are several other procedures, as well.

Prevention

There should be at least one-half inch between the tip of your longest toe and the front of the shoe. Never buy shoes that feel tight and expect them to stretch with wearing. If you have prominent areas on your feet such as hammertoes and bunions, avoid shoes with a lot of stitching or multiple pieces of fabric, as these stitched areas tend not to stretch to accommodate various toe deformities.
