Overview
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.

Causes
While most cases of hammertoes are caused by an underying muscle imbalance, it may develop as a result of several different causes, including arthritis, a hereditary condition, an injury, or ill-fitting shoes. In some cases, patients develop hammertoes after wearing shoes or stockings that are too tight for long periods of time. These patients usually develop hammertoes in both feet.

Symptoms
People with a hammer toe will often find that a corn or callus will develop on the top of the toe, where it rubs against the top of the footwear. This can be painful when pressure is applied or when anything rubs on it. The affected joint may also be painful and appear swollen.

Diagnosis
Your doctor is very likely to be able to diagnose your hammertoe simply by examining your foot. Even before that, he or she will probably ask about your family and personal medical history and evaluate your gait as you walk and the types of shoes you wear. You'll be asked about your symptoms, when they started and when they occur. You may also be asked to flex your toe so that your doctor can get an idea of your range of motion. He or she may order x-rays in order to better define your deformity.

Non Surgical Treatment
Treating hammertoe involves straightening the toe, making tendons in the toes flexible again, and preventing the problem from returning. Some simple treatments include splinting the toe to keep it straight and to stretch the tendons of the foot. Using over-the-counter pads, cushions or straps to decrease discomfort Exercising the toes to relax the foot tendons (a session with a physical therapist may help you get started with foot exercises) Wearing shoes that fit properly and allow toes plenty of room to stretch out.

Surgical Treatment
The deformity is corrected in a variety of ways. There are actually a large number of procedures. The simplest procedure would involve a Tenotomy, the cutting of the tendon causing the deformity or a Tendon Lengthening procedure. These procedures are infrequently done, though, as the structural deformity (the arthritis and joint adaptation) is not addressed with these surgeries. Other soft-tissue procedures involve rebalancing the tendons around the joint. There are several techniques to do this, but the most common is probably the Girdlestone-Taylor procedure, which involves rerouting the tendons on the bottom of the toe up and over the toe where it sticks up, so that the tendon helps pull the toe downwards into proper alignment.

Prevention
What to do after you wear your high heels to avoid getting the hammertoes has to do with stretching and opening up the front of the foot. There?s a great product called Yoga Toes that you can slide on your foot and it will stretch and open up all of the toes, elongating and stretching the muscles in the front of the foot. I also advise people to stretch the back of their legs, which is the calf muscle, which puts much less pressure on the front of the foot. The less pressure you have on the front of the foot, the less the foot will contract in and start creating the hammertoes.
