Hammer toes are classified based on the mobility of the toe joints. There are two types. Flexible and rigid. In a flexible Hammer toe, the joint has the ability to move. This type of hammer toe can be straightened manually. A rigid hammer toe does not have that same ability to move. Movement is very limited and can be extremely painful. This sometimes causes foot movement to become restricted leading to extra stress at the ball-of-the-foot, and possibly causing pain and the development of corns and calluses.
Causes
It is possible to be born with a hammer toe, however many people develop the deformity later in life. Common causes include tightened tendons that cause the toe to curl downward. Nerve injuries or problems with the spinal cord. Stubbing, jamming or breaking a toe. Having a stroke. Being a diabetic. Having a second toe that is longer than the big toe. Wearing high heels or tight shoes that crowd the toes and don?t allow them to lie flat. Aging.

Here is a look at some of the symptoms hammertoe can cause. They include hammer-like or claw-like appearance of the toe. Pain when walking or moving the foot. Difficulty moving the toe. Corns may form on top of the toe. Callus may form on the sole of the foot. During the initial stages, you may be able to manually straighten your toe. This is called a flexible hammertoe. But as time passes, the toe will not move as easily and will continue to look like a hammer. Pressure and irritation over the joint can cause a blister to develop and become a corn over time. These corns have the potential to become infected and cause additional symptoms such as redness, bleeding, and difficulty wearing shoes and socks. Corns are the main cause of pain when hammertoes are developing.
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 Hammer toe 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 If the deformed toe is very painful, your doctor may recommend that you have a fluid sample withdrawn from the joint with a needle so the fluid can be checked for signs of infection or gout (arthritis from crystal deposits).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
People with a hammer toe benefit from wearing shoes in which the toe box is made of a flexible material and is wide enough and high enough to provide adequate room for the toes. High-heeled shoes should be avoided, because they tend to force the toes into a narrow, flat toe box. A doctor may recommend an insert (orthotic) for the shoe to help reduce friction and pressure on the hammer toe. Wearing properly fitted shoes may reduce pain and inflammation. It may also prevent ulcers from developing and help existing ulcers heal. However, the hammer toe does not disappear.
Surgical Treatment
If you are unable to flex your toe, surgery is the only option to restore movement. Surgery is used to reposition the toe, remove deformed or injured bone, and realign your tendons. Surgery is normally done on an outpatient basis, so you can return home on the day of your surgery.
