Overview
The smallest four toes of each foot have three bony segments connected by two joints, just as the fingers do. Hammer Toe 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
A common cause of hammer toe is wearing shoes that do not fit properly. Poorly-fitting shoes can hold the toes in an abnormal position and result in tightening of the muscles required to maintain that position. In particular, shoes that have high heels and are narrow at front tend to push the toes into an abnormal, bent position. Less commonly, diseases of the nerves, muscles, or joints (such as arthritis) can result in the hammer toe deformity.

Symptoms
For some people, a hammer toe is nothing more than an unsightly deformity that detracts from the appearance of the foot. However, discomfort may develop if a corn or callus develops on the end or top of the toe. If pressure and friction continue on the end or top of the toe, a painful ulcer may develop. Discomfort or pain can lead to difficulty walking.

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
You can usually use over-the-counter cushions, pads, or medications to treat bunions and corns. However, if they are painful or if they have caused your toes to become deformed, your doctor may opt to surgically remove them. If you have blisters on your toes, do not pop them. Popping blisters can cause pain and infection. Use over-the-counter creams and cushions to relieve pain and keep blisters from rubbing against the inside of your shoes. Gently stretching your toes can also help relieve pain and reposition the affected toe.

Surgical Treatment
Surgery may not help how your foot looks. And your toe problems may also come back after surgery. This is more likely if you keep wearing the kinds of shoes that cause toe problems. Your expectations will play a large role in how you feel about the results of surgery. If you are only having surgery to improve the way your foot looks, you may not be happy with how it turns out.
