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.
Ill-fitting shoes or a muscle imbalance are the most common causes of Hammer Toe. If there is an issue with a muscle in the second, third or fourth toes preventing them from straightening, Hammer Toe can result. If one of these toes is bent long enough in one position, the muscles tighten and cannot stretch out. Left untreated, surgery may be required. Women are especially prone to developing Hammer Toe because of their shoes. Hammer Toe results from shoes that don?t fit properly. Shoes that narrow toward the toe, pushing smaller toes into a bend position for extended periods of time. High heels that force the foot down into a narrow space, forcing the toes against the shoe, increasing the bend in the toe.
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.
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
Any forefoot problems that cause pain or discomfort should be given prompt attention. Ignoring the symptoms can aggravate the condition and lead to a breakdown of tissue, or possibly even infection. Conservative treatment of mallet toes begins with accommodating the deformity. The goal is to relieve pressure, reduce friction, and transfer forces from the sensitive areas. Shoes with a high and broad toe box (toe area) are recommended for people suffering from forefoot deformities such as mallet toes. This prevents further irritation in the toe area from developing. Other conservative treatment includes forefoot supports such as gel toe caps, gel toe shields and toe crests. Gel forefoot supports provide immediate comfort and relief from common forefoot disorders without drying the skin.
For the surgical correction of a rigid hammertoe, the surgical procedure consists of removing the damaged skin where the corn is located. Then a small section of bone is removed at the level of the rigid joint. The sutures remain in place for approximately ten days. During this period of time it is important to keep the area dry. Most surgeons prefer to leave the bandage in place until the patient's follow-up visit, so there is no need for the patient to change the bandages at home. The patient is returned to a stiff-soled walking shoe in about two weeks. It is important to try and stay off the foot as much as possible during this time. Excessive swelling of the toe is the most common patient complaint. In severe cases of hammertoe deformity a pin may be required to hold the toe in place and the surgeon may elect to fuse the bones in the toe. This requires several weeks of recovery.
Preventing foot problems, including hammertoes, is often a matter of wearing the right shoes and taking care of your feet. Check your feet regularly for problems. This is especially true if you have diabetes or any other medical condition that causes poor circulation or numbness in your toes. If you do, check feet daily so that problems can be caught early on.
