Hammer ToeOverview


The smallest four toes of each foot have three bony segments connected by two joints, just as the fingers do. Hammer toes is a deformity in which one or more of the small toes develops a bend at the joint between the first and second segments so that the tip of the toe turns downward, making it looks like a hammer or claw. The second toe is affected most often.


Causes


Hammer toe is often caused by wearing shoes that do not fit properly. If shoes are too small either in length or width, then the toes are held in a shortened position for long periods and the muscles eventually shorten and pull the toes into the bent position. Alternatively it can be caused by overactivity in the extensor digitorum dongus muscle (right) and a weakness in the counteracting muscle under the foot, such as flexor digitorum longus. Sometimes it can be a congenital condition, meaning it is present from birth. It is also more common in those with arthritis in the foot or diabetes.


Hammer ToeSymptoms


Common symptoms of hammertoes include pain or irritation of the affected toe when wearing shoes. corns and calluses (a buildup of skin) on the toe, between two toes, or on the ball of the foot. Corns are caused by constant friction against the shoe. They may be soft or hard, depending upon their location. Inflammation, redness, or a burning sensation. Contracture of the toe. In more severe cases of hammertoe, open sores may form.


Diagnosis


First push up on the bottom of the metatarsal head associated with the affected toe and see if the toe straightens out. If it does, then an orthotic could correct the problem, usually with a metatarsal pad. If the toe does not straighten out when the metatarsal head is pushed up, then that indicates that contracture in the capsule and ligaments (capsule contracts because the joint was in the wrong position for too long) of the MTP joint has set in and surgery is required. Orthotics are generally required post-surgically.


Non Surgical Treatment


Changing the type of footwear worn is a very important step in the treatment of hammer toes. When choosing a shoe, make sure the toe box (toe area) is high and broad, and can accommodate the hammer toes. A shoe with a high, broad toe box will provide enough room in the forefoot area so that there is less friction against the toes. Other conservative treatments include using forefoot products designed to relieve hammer toes, such as hammer toe crests and hammer toe splints. These devices will help hold down the hammer toe and provide relief to the forefoot. Gel toe shields and gel toe caps are also recommended to eliminate friction between the shoe and the toe, while providing comfort and lubrication.


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 Hammer toes or rod into the toe and alteration or repair of the tendons, so that the toe is straightened. After surgery, the deformity rarely recurs.


HammertoePrevention


In some cases foot problems may present at birth, many foot problems such as hammer toes can be prevented. Hammer toe prevention can be a simple process, such as, checking your feet regularly and wearing the right shoes for your feet. Good circulation is also an essential part of foot health and hammer toe prevention. Taking a warm foot bath or giving yourself a foot massage are great ways of keeping your feet healthy.
