A Hammer toes is the result of deformed toe joints, tight tendons that attach to the toe, and misaligned toe bones. The usual appearance of a hammertoe is a toe 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 so that, instead of the entire toe bearing weight, only the tip of the toe bears weight. Pain can occur on the top of the toe, the tip of the toe, or in both areas.
While most cases of hammertoes are caused by an underlying muscle imbalance, it may develop as a result of several different causes, including arthritis, a hereditary condition, an injury, or ill-fitting shoes. In some cases, patients develop hammertoes after wearing shoes or stockings that are too tight for long periods of time. These patients usually develop hammertoes in both feet.
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.
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
Your doctor will decide what type of hammertoe you have and rule out other medical conditions. Treatment may range from more appropriate footgear to periodic trimming and padding of the corn. Cortisone injections may be indicated if a bursitis is present. Antibiotics may be utilized in the presence of infection. Removable accommodative pads may be made for you.
A variety of anaesthetic techniques are possible. Be sure an discuss this with your surgeon during your pre-op assessment. The type of surgery performed will depend on the problem with your toes and may involve releasing or lengthening tendons, putting joints back into place, straightening a toe and changing the shape of a bone.Your surgeon may fix the toes in place with wires or tiny screws.
