Hammer toe 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.
While there are a number of causes, there aren't many specific risk factors for hammertoes, women tend to get these problems more than men, but they occur without rhyme or reason. Diabetics, however, are more likely to get a hammertoe if they have underlying nerve damage in the toes and feet.
Hammer, claw, and mallet toes can cause discomfort and pain and may make it hard to walk. Shoes may rub on your toes, causing pain, blisters, calluses or corns, or sores. Sores can become infected and lead to cellulitis or osteomyelitis, especially if you have diabetes or peripheral arterial disease. If you have one of these health problems and sores develop, contact your doctor.
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
Podiatric Care may include using anti-inflammatory oral medications or an injection of medication and local anesthetic to reduce this swelling. When you go to your doctor, x-rays are usually required to evaluate the structure of your hammertoes foot, check for fractures and determine the cause. The podiatrist may see you to take care of any corns that develop due to the bone deformities. They may advise you on different shoewear or prescribe a custom made orthotic to try and control the foot structure. Padding techniques may be used to straighten the toe if the deformity is flexible, or pads may be used to lessen the pressure on the area of the corn or ulcer. Your podiatric physician may also recommend a surgical procedure to actually fix the structural problem of your foot.
If conservative measures fail to provide relief, or if your hammertoe is in advanced stages with rigidity and a significant amount of pain, surgery may be required. Some patients also require surgery if they have open sores or wounds related to their hammertoe. For patients who also suffer from bunions, a combined procedure may be appropriate, addressing both conditions within the same surgery. Recovery time will vary from patient to patient, depending on the extent of the surgical repair and other conditions that may also be present.
Avoid wearing shoes that are too short or narrow. Check children's shoe sizes often, especially during periods of fast growth. If you have hammer toe, call for an appointment with your health care provider. If you develop thick blisters or corns on your toes, if your pain gets worse, if you have difficulty walking call for an appointment with your health care provider.
