Overview
A Hammer Toe is a term that is commonly used to describe any type of toe deformity. It is a common problem that may or may not be a problem. What does a hammer toe look like? In a hammertoe the deformity usually exists in one toe (at the proximal inter phalangeal joint) - the base of the toe points upward and the end of the toe points down.

Causes
The main cause of hammer toe is poorly fitted and/or poorly designed footwear. Any footwear that is too tight in the toe box, especially high-heeled shoes, can push the toes forward, crowding one or more of them into a space that is not large enough to allow the toes to lie flat and spread as they should. Other causes include the following. Changes in foot anatomy. Sometimes the metatarsal bones in the ball of the foot can ?drop,? creating a situation in which the toes do not make contact with the surface of the shoe. The toes may then contract at one or both of the joints to re-establish contact with the surface. Traumatic injuries in which toes are jammed or broken. Diabetic neuropathy. This can cause abnormal foot biomechanics due to nerve and/or muscle damage. Damage to nerves and muscles from other conditions, such as arthritis or stroke. Heredity.

Symptoms
Pain upon pressure at the top of the bent toe from footwear. The formation of corns on the top of the joint. Redness and swelling at the joint contracture. Restricted or painful motion of the toe joint. Pain in the ball of the foot at the base of the affected toe.

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
Any forefoot problems that cause pain or discomfort should be given prompt attention. Ignoring the symptoms can aggravate the condition and lead to a breakdown of tissue, or possibly even infection. Conservative treatment of mallet toes begins with accommodating the deformity. The goal is to relieve pressure, reduce friction, and transfer forces from the sensitive areas. Shoes with a high and broad toe box (toe area) are recommended for people suffering from forefoot deformities such as mallet toes. This prevents further irritation in the toe area from developing. Other conservative treatment includes forefoot supports such as gel toe caps, gel toe shields and toe crests. Gel forefoot supports provide immediate comfort and relief from common forefoot disorders without drying the skin.

Surgical Treatment
If your hammer, claw, or mallet toe gets worse, or if nonsurgical treatment does not help your pain, you may think about surgery. The type of surgery you choose depends on how severe your condition is and whether the toe joint is fixed (has no movement) or flexible (has some movement). A fixed toe joint often requires surgery to be straightened. A flexible toe joint can sometimes be straightened without surgery. Surgery choices include Phalangeal head resection (arthroplasty), in which the surgeon removes part of the toe bone. Joint fusion (arthrodesis), in which the surgeon removes part of the joint, letting the toe bones grow together (fuse). Cutting supporting tissue or moving tendons in the toe joint. How well surgery works depends on what type of surgery you have, how experienced your surgeon is, and how badly your toes are affected.
