OverviewHammertoes is a type of crooked toe that involve unnatural contracture, or bending, of your toes. In most cases, a hammertoe is characterized by a toe malposition in which the end of your affected toe points down and the first joint of your same toe-your proximal interphalangeal joint-points up. This crooked toe syndrome usually leads to rubbing within your shoe and pain. A hammertoe resembles an upside-down letter v when viewed from the side. This crooked toe syndrome most commonly affects your second to fifth toes, though it may also affect your big toe. This health problem is more commonly experienced by women than men.
Causes
Hammertoe has three main culprits: tight shoes, trauma, and nerve injuries or disorders. When toes are crowded in shoes that are too tight and narrow, they are unable to rest flat, and this curled toe position may become permanent even when you aren't wearing shoes due to the tendons of the toe permanently tightening. When the tendons are held in one position for too long, the muscles tighten and eventually become unable to stretch back out. A similar situation may result when tendons are injured due to trauma, such as a stubbed, jammed, or broken toe.
Symptoms
Symptoms include sharp pain in the middle of the toe and difficulty straightening the toe. People with hammertoe may also develop blisters, which are fluid-filled pockets of skin, because the bent toe is likely to rub against the inside of a shoe. This increased friction may also lead to calluses, which are areas of thickened skin, and corns, which are hard lumps that may form on or between toes. Symptoms may be minor at first, but they can worsen over time.
Diagnosis
First push up on the bottom of the metatarsal head associated with the affected toe and see if the toe straightens out. If it does, then an orthotic could correct the problem, usually with a metatarsal pad. If the toe does not straighten out when the metatarsal head is pushed up, then that indicates that contracture in the capsule and ligaments (capsule contracts because the joint was in the wrong position for too long) of the MTP joint has set in and surgery is required. Orthotics are generally required post-surgically.
Non Surgical Treatment
Symptoms of hammer toe might be helped through corn pads or cushions to alleviate them. If the person's hammer toes were caused by an underlying disease, the person should ask for their doctor's advice prior to performing any exercises without consent. It is also important for a person with hammer toes to remember that they must not attempt to treat or remove corns by themselves. If open cuts result from attempts to remove them, an infection becomes a very real possibility. People who experience diabetes or conditions that lead to poor circulation in their feet need to be especially careful.
Surgical Treatment
The deformity is corrected in a variety of ways. There are actually a large number of procedures. The simplest procedure would involve a Tenotomy, the cutting of the tendon causing the deformity or a Tendon Lengthening procedure. These procedures are infrequently done, though, as the structural deformity (the arthritis and joint adaptation) is not addressed with these surgeries. Other soft-tissue procedures involve rebalancing the tendons around the joint. There are several techniques to do this, but the most common is probably the Girdlestone-Taylor procedure, which involves rerouting the tendons on the bottom of the toe up and over the toe where it sticks up, so that the tendon helps pull the toe downwards into proper alignment.
