hammertoes is a Z-shaped deformity caused by dorsal subluxation at the metatarsophalangeal joint. Diagnosis is clinical. Treatment is modification of footwear and/or orthotics. The usual cause is misalignment of the joint surfaces due to a genetic predisposition toward aberrant foot biomechanics and tendon contractures. RA and neurologic disorders such as Charcot-Marie-Tooth disease are other causes.
Hammer toe may also be caused by other medical conditions such as rheumatoid arthritis, osteoarthritis, or stroke because these forms of illnesses involve affectation of the person's muscles and nerves. Diabetes is also a causative factor for hammer toes due to diabetic neuropathy, which often times accompanies advanced instances of diabetes. Injury to a person's toes may also cause hammer toes, particularly if the injury involves breaking of the toes. In some instances, hammer toes may be hereditary. Some people may be genetically predisposed to develop the condition because of the natural structure of their bodies.
Pain upon pressure at the top of the bent toe from footwear. The formation of corns on the top of the Hammer toe 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.
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
Inserts in your shoes can be used to help relieve pressure on the toes from the deformity. Splints/Straps. These can be used to help re-align and stretch your toes and correct the muscle imbalance and tendon shortening. One of the most common types are toe stretchers like the yogatoe. Chiropody. A chiropodist can remove calluses or corns, areas of hard skin that have formed to make the foot more comfortable.Steroid injections can help to reduce pain and inflammation.
Surgery is the approach that is often necessary to correct hammertoe that fails to respond to nonsurgical management. Surgery is appropriate when the muscles and tendons involved in a hammertoe problem have become so tight that the joints are rigid, misaligned and unmovable. There are a number of surgical techniques for dealing with the complex range of joint, bone, muscle, tendon and ligament abnormalities that define each hammertoe's make-up. To correct a hammertoe deformity, the surgeon's goal is to restore the normal alignment of the toe joint, relieving the pressure that led to the hammertoe's development (this should also relieve the pain, as well). To do this, he or she may remove part of the boney structure that creates a prominence at the top of the joint. Tighten or loosen the muscles, tendons and ligaments around the toe joints. Realign the toe bones by cutting one or more and shifting their position, realigning muscles, tendons and ligaments accordingly. Use screws, wires or plates to hold the joint surfaces together until they heal. Reconstruct a badly damaged joint or replace it with an artificial implant.
Hammertoe can usually be prevented by wearing shoes that fit properly and give the toes plenty of room. Don?t wear shoes with pointed or narrow toes. Don?t wear shoes that are too tight or short. Don?t wear high-heeled shoes, which can force the toes forward. Choose shoes with wide or boxy toes. Choose shoes that are a half-inch longer than your longest toe. If shoes hurt, don?t wear them.
