Overview
A Hammer Toe is a contracture, or bending, of the toe at the first joint of the digit, called the proximal interphalangeal joint. This bending causes the toe to appear like an upside-down V when looked at from the side. Any toe can be involved, but the condition usually affects the second through fifth toes, known as the lesser digits. Hammer toes are more common in females than males.

Causes
Hammertoe and mallet toe have been linked to certain shoes. High-heeled shoes or footwear that's too tight in the toe box can crowd your toes into a space that's not large enough for them to lie flat. This curled toe position may eventually persist even when you're barefoot. Trauma. An injury in which you stub, jam or break a toe may make it more likely for that digit to develop hammertoe or mallet toe. Nerve injuries or disorders. Hammertoe and mallet toe are more common in people who have nerve damage in their feet, which often occurs with such medical problems as a stroke or diabetes.

Symptoms
The most obvious sign of hammertoes are bent toes, other symptoms may include pain and stiffness during movement of the toe. Painful corns on the tops of the toe or toes from rubbing against the top of the shoe's toe box. Painful calluses on the bottoms of the toe or toes. Pain on the bottom of the ball of the foot. Redness and swelling at the joints.

Diagnosis
Although hammertoes are readily apparent, to arrive at a diagnosis the foot and ankle surgeon will obtain a thorough history of your symptoms and examine your foot. During the physical examination, the doctor may attempt to reproduce your symptoms by manipulating your foot and will study the contractures of the toes. In addition, the foot and ankle surgeon may take x-rays to determine the degree of the deformities and assess any changes that may have occurred.

Non Surgical Treatment
If the toes are still mobile enough that they are able to stretch out and lay flat, the doctor will likely suggest a change of footwear. In addition, she may choose to treat the pain that may result from the condition. The doctor may prescribe pads to ease the pain of any corns and calluses, and medications ranging from ibuprofen to steroid injections for the inflammation and pain. Other options for non-surgical treatments include orthotic devices to help with the tendon and muscle imbalance or splinting to help realign the toe. Splinting devices come in a variety of shapes and sizes but the purpose of each is the same: to stretch the muscles and tendon and flatten the joint to remove the pain and pressure that comes from corns.

Surgical Treatment
If pinning the toe is not required during the procedure, then the surgery could be preformed in the doctor's office under a local anesthesia. Some patients prefer the comfort of sedation during the surgery and if this is the case or if a pin must be placed, then the surgery could be preformed in an outpatient surgery center.

Prevention
Walking barefoot increases the risk for injury and infection. Being on your feet throughout the day can cause them to swell, this is the best time to buy shoes to get a better fit. Do not buy shoes that feel tight. Do not buy shoes that ride up and down your heel as you walk. The ball of your foot should fit into the widest part of the shoe. Remember, the higher the heel the less safe the shoe will be. Avoid shoes with pointed or narrow toes. If the shoes hurt, do not wear them. If you start noticing the beginning signs of hammer toes, you may still be able to prevent the tendons from tightening by soaking your feet every day in warm water, wearing toe friendly shoes, and performing foot exercises such as stretching your toes and ankles. A simple exercise such as placing a small towel on the floor and then picking it up using only your toes can help to restore the flexibility of tendons.
