OverviewThe term Hammertoe describes three unique contracture deformities of the toes. The deformities differ by the location of contracture in each joint of the toe. The three deformities include hammer toe, claw toe and mallet toe. Hammer toes may be flexible or rigid. Hammer toes are most common on the lesser toes (2-5) and may affect one or more toes simultaneously. Hallux malleus is the term used to described a hammer toe of the great toe. Hallux malleus is often found as an isolated foot problem. Hammer toes are found equally in men and women. The onset of hammer toes is between the ages of 30 and 80 years of age.
Causes
Most hammertoes are caused by wearing ill-fitting, tight or high-heeled shoes over a long period of time. Shoes that don't fit well can crowd the toes, putting pressure on the middle toes and causing them to curl downward. The condition may be more likely when the second toe is longer than the first toe or when the arch of the foot is flat. Hammertoe can also be present at birth (congenital). Hammertoe also can be caused by a bunion, which is the knobby bump that sometimes develops at the side of the big toe. A bunion causes the big toe to bend toward the other toes. The big toe can then overlap and crowd the smaller toes. Occasionally, a hammertoe is inherited or caused by arthritis in the toe joint.
Symptoms
A hammertoe may be present but not always painful unless irritated by shoes. One may have enlarged toe joints with some thickened skin and no redness or swelling. However, if shoes create pressure on the joint, the pain will usually range from pinching and squeezing to sharp and burning. In long standing conditions, the dislocated joints can cause the pain of arthritis.
Diagnosis
Hammer toes may be easily detected through observation. The malformation of the person's toes begin as mild distortions, yet may worsen over time - especially if the factors causing the hammer toes are not eased or removed. If the condition is paid attention to early enough, the person's toes may not be permanently damaged and may be treated without having to receive surgical intervention. If the person's toes remain untreated for too long, however the muscles within the toes might stiffen even more and will require invasive procedures to correct the deformity.
Non Surgical Treatment
Changing the type of footwear worn is a very important step in the treatment of hammer toes. When choosing a shoe, make sure the toe box (toe area) is high and broad, and can accommodate the hammer toes. A shoe with a high, broad toe box will provide enough room in the forefoot area so that there is less friction against the toes. Other conservative treatments include using forefoot products designed to relieve hammer toes, such as hammer toe crests and hammer toe splints. These devices will help hold down the hammer toe and provide relief to the forefoot. Gel toe shields and gel toe caps are also recommended to eliminate friction between the shoe and the toe, while providing comfort and lubrication.
Surgical Treatment
Surgery is the approach that is often necessary to correct hammertoe that fails to respond to nonsurgical management. Surgery is appropriate when the muscles and tendons involved in a hammertoe problem have become so tight that the joints are rigid, misaligned and unmovable. There are a number of surgical techniques for dealing with the complex range of joint, bone, muscle, tendon and ligament abnormalities that define each hammertoe's make-up. To correct a hammertoe deformity, the surgeon's goal is to restore the normal alignment of the toe joint, relieving the pressure that led to the hammertoe's development (this should also relieve the pain, as well). To do this, he or she may remove part of the boney structure that creates a prominence at the top of the joint. Tighten or loosen the muscles, tendons and ligaments around the toe joints. Realign the toe bones by cutting one or more and shifting their position, realigning muscles, tendons and ligaments accordingly. Use screws, wires or plates to hold the joint surfaces together until they heal. Reconstruct a badly damaged joint or replace it with an artificial implant.
Prevention
To help prevent hammertoe, wear roomy, low-heeled shoes that allow plenty of width and length for the toes. The Mayo Clinic recommends wearing shoes that have at least 1/2 inch of space between the shoe and the longest toe.
