Overview
Hammer toes is foot deformity that typically affects second, third or fourth toes. The condition is called hammertoe because of the unnatural position your toes form. Hammertoe causes your toe to bend upward at the middle joint in a way that looks similar to a hammer. While it may not be painful at first, this condition usually worsens with time and it becomes difficult to extend your toes. Sometimes, calluses or corns form in association with hammertoe.

Causes
Footwear is actually the leading cause of this type of toe deformity so much so that people sometimes require hammer toe surgery to undo some of the damage. The most common problem is wearing shoes that are too short, too narrow or too tight. These shoes constricts the feet and force the toes into a bend position. Women are more at risk especially due to high heels. Footwear isn?t the only problem, poor foot posture can lead to muscle and even bone imbalances. This asymmetry can cause excessive strain on the toes either by forcing the toe into unnatural positions. Arthritis can also play a factor in the development of hammer toe, especially if the toe joint is stiff and incapable of a full range of motion.

Symptoms
Some people never have troubles with hammer toes. In fact, some people don't even know they have them. They can become uncomfortable, especially while wearing shoes. Many people who develop symptoms with hammer toes will develop corns, blisters and pain on the top of the toe, where it rubs against the shoe or between the toes, where it rubs against the adjacent toe. You can also develop calluses on the balls of the feet, as well as cramping, aching and an overall fatigue in the foot and leg.

Diagnosis
Most health care professionals can diagnose hammertoe simply by examining your toes and feet. X-rays of the feet are not needed to diagnose hammertoe, but they may be useful to look for signs of some types of arthritis (such as rheumatoid arthritis) or other disorders that can cause hammertoe. If the deformed toe is very painful, your doctor may recommend that you have a fluid sample withdrawn from the joint with a needle so the fluid can be checked for signs of infection or gout (arthritis from crystal deposits).

Non Surgical Treatment
You should seek medical advice if you have a hammer toe. Here are some things you can do in the meantime. None of these things will cure the hammer toe, but they may relieve the pain and discomfort. Only wear shoes that are high and broad across the toes. There should be at least 1.5 cm of space between your longest toe and the tip of the shoe. Keep in mind that this could be either your big toe or your second toe. Don't wear heels higher than 5 cm. Wear the appropriate shoe for the activity you are doing. You can buy non-medicated hammer toe pads. They fit around the pointy top of the toe joint and help relieve painful pressure. Gently massaging the toe may help relieve pain. Put ice packs wrapped in cloth on the hammer toe to reduce painful swelling.

Surgical Treatment
In more advanced cases of hammer toe, or when the accompanying pain cannot be relieved by conservative treatment, surgery may be required. Different types of surgical procedures are performed to correct hammer toe, depending on the location and extent of the problem. Surgical treatment is generally effective for both flexible and fixed (rigid) forms of hammer toe. Recurrence following surgery may develop in persons with flexible hammer toe, particularly if they resume wearing poorly-fitted shoes after the deformity is corrected.

Prevention
The best first step you can take is to evaluate your shoe choices. Ditch any shoes that aren?t serving your feet well. Shoes that crowd the front of your foot, especially around your toes, aggravate the existing condition and can also cause the condition to develop. If you suspect the development of hammertoe, you may also try using protective pads to prevent irritation and the development of corns. Custom orthotics to correct muscle imbalances in your feet may also help prevent hammertoe.
