OverviewA Hammertoe is commonly mistaken as any type of toe deformity. The terms claw toe, or mallet toe, although technically different than a hammer toe, are commonly referred as such. The toe may be flexible with movement at the joints, or it may be rigid, especially if it has been present for a long time. With a true hammertoe the deformity exists at the proximal interphalangeal joint only.
Causes
Essentially, hammertoes are caused by an abnormal interworking of the bones, muscles, ligaments and tendons that comprise your feet. When muscles fail to work in a balanced manner, the toe joints can bend to form the hammertoe shape. If they remain in this position for an extended period, the muscles and tendons supporting them tighten and remain in that position. A common factor in development of hammertoe is wearing shoes that squeeze the toes or high heels that jam the toes into the front of the shoe. Most likely due to these factors, hammertoe occurs much more frequently in women than in men.
Symptoms
Hammer, claw, and mallet toes can cause discomfort and pain and may make it hard to walk. Shoes may rub on your toes, causing pain, blisters, calluses or corns, or sores. Sores can become infected and lead to cellulitis or osteomyelitis, especially if you have diabetes or peripheral arterial disease. If you have one of these health problems and sores develop, contact your doctor.
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
Wear wide shoes with plenty of room in the toes and resilient soles. Avoid wearing shoes with pointed toes. Commercially available felt pads or cushions may ease pressure from the shoe on the toe. Toe caps (small, padded sleeves that fit around the tip of the toe) may relieve the pain of hammer toe. Do toe exercises, to help toe muscles become stronger and more flexible.Arch supports or an orthotic shoe insert prescribed by your doctor or podiatrist may help to redistribute weight on the foot. These devices do not cure the problem but may ease the symptoms of either hammer toe or mallet toe.
Surgical Treatment
Surgery to straighten the toe may be needed if an ulcer has formed on either the end or the top surface of the toe. Surgery sometimes involves cutting the tendons that support movement in the toe so that the toe can be straightened. Cutting the tendons, however, takes away the ability to bend the very end of the toe. Another type of surgery combines temporary insertion of a pin or rod into the toe and alteration or repair of the tendons, so that the toe is straightened. After surgery, the deformity rarely recurs.
