Overview The term, Hammer toes is used to describe the collective physical deformity of the second, third and fourth toe on a person's foot when they are permanently bent at one or two of their joints, often times at their middle joints or, 'proximal interphalangeal,' joints. The condition is also referred to as, 'contracted toes,' and earned its name for the resulting bowed appearance of the toes that made them appear similar to hammers. The distortion of the usual contour of the person's toes is usually a result of wearing shoes that are too short or narrow and apply consistent pressure to the toes, forcing them to be pushed together and lie obliquely. The situation is particularly true in the case of shoes that are designed to narrow towards the toe box. Causes It is possible to be born with a hammer toe, however many people develop the deformity later in life. Common causes include tightened tendons that cause the toe to curl downward. Nerve injuries or problems with the spinal cord. Stubbing, jamming or breaking a toe. Having a stroke. Being a diabetic. Having a second toe that is longer than the big toe. Wearing high heels or tight shoes that crowd the toes and don?t allow them to lie flat. Aging. Symptoms The symptoms of a hammer toe are usually first noticed when a corn develops on the top of the toe and becomes painful, usually when wearing tight shoes. There may be a bursa under the corn or instead of a corn, depending on the pressure. Most of the symptoms are due to pressure from footwear on the toe. There may be a callus under the metatarsal head at the base of the toe. Initially a hammer toe is usually flexible, but when longstanding it becomes more rigid. Diagnosis The treatment options vary with the type and severity of each hammer toe, although identifying the deformity early in its development is important to avoid surgery. Your podiatric physician will examine and X-ray the affected area and recommend a treatment plan specific to your condition. Non Surgical Treatment In many cases, conservative treatment consisting of physical therapy and new shoes with soft, spacious toe boxes is enough to resolve the condition, while in more severe or longstanding cases podiatric surgery may be necessary to correct the deformity. The patient's doctor may also prescribe some toe exercises that can be done at home to stretch and strengthen the muscles. For example, the individual can gently stretch the toes manually, or use the toes to pick things up off the floor. While watching television or reading, one can put a towel flat under the feet and use the toes to crumple it. The doctor can also prescribe a brace that pushes down on the toes to force them to stretch out their muscles. Surgical Treatment 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. Prevention You can avoid many foot, heel and ankle problems with shoes that fit properly. Here's what to look for when buying shoes. Adequate toe room. Avoid shoes with pointed toes. Low heels. Avoiding high heels will help you avoid back problems. Adjustability. Laced shoes are roomier and adjustable. お気に入りの記事を「いいね!」で応援しよう
