OverviewThe name Hammer Toe 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
Hammertoe commonly develops because of structural changes that take place over time in the muscles and tendons that bend the toes. People with certain medical conditions, such as diabetes, are at risk for developing hammertoe. It can be an inherited condition for some people. Other causes include trauma and wearing shoes that are too tight, narrow, or have high heels. The toe next to the big toe (second toe) is most frequently affected by hammertoe.

Symptoms
The symptoms of hammertoe are progressive, meaning that they get worse over time. Hammertoe causes the middle joint on the second, third, fourth, or fifth toes to bend. The affected toe may be painful or irritated, especially when you wear shoes. Areas of thickened skin (corns) may develop between, on top of, or at the end of your toes. Thickened skin (calluses) may also appear on the bottom of your toe or the ball of your foot. It may be difficult to find a pair of shoes that is comfortable to wear.
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.
Non Surgical Treatment
A person with hammer toes will be asked to practice some exercises for their toes to regain average structure and movement. The exercises usually involve stretching and strengthening their toes. The person may attempt to pick things up off the floor using only their toes. They may also stretch their toes on a regular basis by hand to ease them into straightening out. Another example of a physical exercise specifically for a person's toes involves crumpling a towel with the toes. The towel can lie underneath the person's feet and the person can use their toes to scrunch up the towel as they perform simple tasks such as reading a book or watching television.
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.
