Hammer toes 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.
Poorly fitting shoes and muscle imbalances are the most common causes of hammertoe. When shoes are too narrow or do not accommodate the shape and size of your feet, they often contort the position of your toes. Choosing a shoe that fits is very important when it comes to avoiding foot problems like bunions or hammertoe. Having your toes bent for an extended period of time in a shoe that is too narrow or small forces your toes to adapt to the cramped space. With time, the muscles in your feet become accustomed to holding the flexed position of your toes, making it harder, or even impossible to straighten them.
If the toes remain in the hammertoe position for long periods, the tendons on the top of the foot will tighten over time because they are not stretched to their full length. Eventually, the tendons shorten Hammer toe enough that the toe stays bent, even when shoes are not being worn. The symptoms of hammertoe include a curling toe, pain or discomfort in the toes and ball of the foot or the front of the leg, especially when toes are stretched downward, thickening of the skin above or below the affected toe with the formation of corns or calluses, difficulty finding shoes that fit well. In its early stages, hammertoe is not obvious. Frequently, hammertoe does not cause any symptoms except for the claw-like toe shape.
Your doctor is very likely to be able to diagnose your hammertoe simply by examining your foot. Even before that, he or she will probably ask about your family and personal medical history and evaluate your gait as you walk and the types of shoes you wear. You'll be asked about your symptoms, when they started and when they occur. You may also be asked to flex your toe so that your doctor can get an idea of your range of motion. He or she may order x-rays in order to better define your deformity.
Non Surgical Treatment
Your doctor may prescribe some toe exercises that you can do at home to stretch and strengthen the muscles. For example, you can gently stretch the toes manually. You can use your toes to pick things up off the floor. While you watch television or read, you can put a towel flat under your feet and use your toes to crumple it. Finally, your doctor may recommend that you use commercially available straps, cushions or nonmedicated corn pads to relieve symptoms. If you have diabetes, poor circulation or a lack of feeling in your feet, talk to your doctor before attempting any self-treatment.
Hammertoe surgery is performed when conservative measures have been exhausted and pain or deformity still persists. The surgery is performed on an outpatient basis. It typically required about one hour of time. An incision is placed over the inter-phalangeal joint. Once the bone is exposed, the end portion of the bone is removed. Your surgeon may then use pins or other fixation devices to assist in straightening the toe. These devices may be removed at a later date if necessary. Recovery for hammertoe surgery is approximately 10 to 14 days. You are able to walk immediately following the surgery in a surgical shoe. Swelling may be present but is managed as needed. Physical therapy is used to help reduce swelling in the toe or toes after surgery. Most of these toe surgeries can be performed in the office or the outpatient surgery under local anesthesia.
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.
