Hammertoes are quite common and may range from mild to severe. A Hammertoes is a contracture, or bending, of one or more toes, usually due to an imbalance between the muscles or tendons on the top and bottom of the toes. Over time, the affected toes lose flexibility, becoming rigid and fixed in a contracted position. The abnormal bend positions the knuckle of the toe upward, causing it to push against the top of the shoe leading to additional problems. The condition usually becomes progressively worse if not treated.
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.
At first, a hammertoe or mallet toe may maintain its flexibility and lie flat when you're not wearing crowded footwear. But eventually, the tendons of the toe may contract and tighten, causing your toe to become permanently stiff. Your shoes can rub against the raised portion of the toe or toes, causing painful corns or calluses.
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.
If conservative treatments fail and your symptoms persist, the doctor may recommend a surgical option to straighten the toe. The procedures used vary greatly, depending upon the reasons for the hammertoe. There are a number of different operations to correct hammertoes, the most common ones involve Soft tissue corrections such as tendon transfers, tendon lengthening, and joint capsule repairs. Digital arthroplasty involves removal of bone from the bent joint to allow the toe to straighten. The temporary use of pins or K-wires may be necessary to keep the toe straight during the healing period. Joint implants are sometimes used to allow for a better range of motion in the toe following surgery. Digital arthrodesis involves the removal of bone from the bent joint and fusing the toe in a straight position. If the corn is due to a bone spur, the most common procedure used is an exostectomy, in which surgically removing it or filing it down removes the bone spur. Because of the possible complications involved with any surgery, one should be sure to understand the risks that may be involved with surgery to correct hammertoes and remove bone spurs.
