OverviewHammertoes, also called hammer toe, deformity of the second, third, or fourth toe in which the toe is bent downward at the middle joint (the proximal interphalangeal [PIP] joint), such that the overall shape of the toe resembles a hammer. Most cases of hammertoe involve the second toe, and often only one or two toes are affected. In rare cases when all the toes are involved, a thorough neurological assessment is necessary to evaluate for underlying nerve or spinal cord problems.
Causes
Hammer toe results from shoes that don't fit properly or a muscle imbalance, usually in combination with one or more other factors. Muscles work in pairs to straighten and bend the toes. If the toe is bent and held in one position long enough, the muscles tighten and cannot stretch out. Shoes that narrow toward the toe may make your forefoot look smaller. But they also push the smaller toes into a flexed (bent) position. The toes rub against the shoe, leading to the formation of corns and calluses, which further aggravate the condition. A higher heel forces the foot down and squishes the toes against the shoe, increasing the pressure and the bend in the toe. Eventually, the toe muscles become unable to straighten the toe, even when there is no confining shoe.
Symptoms
Signs and symptoms of hammertoe and mallet toe may include a hammer-like or claw-like appearance of a toe. In mallet toe, a deformity at the end of the toe, giving the toe a mallet-like appearance. Pain and difficulty moving the toe. Corns and calluses resulting from the toe rubbing against the inside of your footwear. Both hammertoe and mallet toe can cause pain with walking and other foot movements.
Diagnosis
Your healthcare provider will examine your foot, checking for redness, swelling, corns, and calluses. Your provider will also measure the flexibility of your toes and test how much feeling you have in your toes. You may have blood tests to check for arthritis, diabetes, and infection.
Non Surgical Treatment
There is a variety of treatment options for hammertoe. The treatment your foot and ankle surgeon selects will depend upon the severity of your hammertoe and other factors. A number of non-surgical measures can be undertaken. Padding corns and calluses. Your foot and ankle surgeon can provide or prescribe pads designed to shield corns from irritation. If you want to try over-the-counter pads, avoid the medicated types. Medicated pads are generally not recommended because they may contain a small amount of acid that can be harmful. Consult your surgeon about this option. Changes in shoewear. Avoid shoes with pointed toes, shoes that are too short, or shoes with high heels, conditions that can force your toe against the front of the shoe. Instead, choose comfortable shoes with a deep, roomy toe box and heels no higher than two inches. Orthotic devices. A custom orthotic device placed in your shoe may help control the muscle/tendon imbalance. Injection therapy. Corticosteroid injections are sometimes used to ease pain and inflammation caused by hammertoe. Medications. Oral nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be recommended to reduce pain and inflammation. Splinting/strapping. Splints or small straps may be applied by the surgeon to realign the bent toe.
Surgical Treatment
Laser surgery is popular for cosmetic procedures, however, for hammer toe surgery it does not offer any advantage to traditional methods. Laser is useful for soft tissues (not bone), and because hammer toe surgery involves bone procedures, it is not effective. For cosmetic hammer toe surgery, patients should look for surgeons experienced in aesthetic foot surgery.
Prevention
As long as hammertoe causes no pain or any change in your walking or running gait, it isn?t harmful and doesn't require treatment. The key to prevention is to wear shoes that fit you properly and provide plenty of room for your toes.
