Overview
The name Hammertoes comes from the way the tip of the toe hits or hammers on the floor with each step. The primary deformity seen in a hammer toe is found at the PIPJ (proximal interphalangeal joint) which is the first or more proximal of the two joints of the toe. A mallet toe, on the other hand, is a similar deformity but is found in the DIPJ (distal interphalangeal joint). And lastly, claw toes are a deformity where the entire toe grabs and involves the MPJ (metatarsal phalangeal joint) PIPJ and DIPJ. Collectively, these deformities are referred to as hammer toes. Hammer toes can affect one or all of the toes simultaneously.

Causes
The incorrect position of the person's toes inside of their shoes also causes the formation of calluses or corns on the surfaces of their toes which are constantly bent as they are wearing inappropriate shoes because the surfaces are consistently rubbing against the hard materials of the interior of the shoes causing regular friction.

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 If the deformed toe is very painful, your doctor may recommend that you have a fluid sample withdrawn from the joint with a needle so the fluid can be checked for signs of infection or gout (arthritis from crystal deposits).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
If you have hammer toe, avoiding tight shoes and high heels may provide relief. Initial (non-surgical) treatment for hammer toe involves wearing shoes with plenty of room in the toe area. Shoes should be at least one-half inch longer than the longest toe. Stretching and strengthening exercises for the toes (such as picking up items with the toes or stretching the toes by hand) are also recommended. Sometimes orthopedists recommend special pads, cushions, or slings to help relieve the pain of hammer toe.

Surgical Treatment
Surgery involves removing a small section of bone from the affected joint through a procedure called arthroplasty. Arthrodesis may also be performed to treat hammertoes, which involves fusing together one of the joints in the toe in order to keep it straight. This procedure requires the use of a metal pin to hold the toe in position while it heals.
