Overview
Hammertoe is a condition in which the toes of your feet become contracted into an upside-down “V” shape, causing pain, pressure and, often, corns and calluses. hammertoes can develop on any of the toes, but generally affects the middle three toes, most often the second toe. The bones, muscles, ligaments and tendons of your feet normally are well-balanced to distribute your body’s weight while standing, walking and running. When the first and second joints of your toes experience the prolonged stress that develops when the muscles that control them fail to work together properly, the pressure on the tendons that support them can lead to the curling or contraction known as hammertoe.
Causes
Footwear can contribute significantly to the development of hammertoes. Shoes that are too small force your toes into a curled position. Over time, your toe tendons adjust to this positioning, causing your toe or toes to hold a hammered shape. Athletes may be especially susceptible, because of the increased forces on the toes from shoes that are too small or tight. Heel elevation in footwear is also problematic, as it causes your toes to be pushed into the shoe?s toe box. Heel elevation additionally contributes to muscle imbalance. A common example of this is when your Achilles tendon-the tendon at the back of your leg that attaches your calf muscles to your heel bone-is too tight, causing the tendons on the top of your foot that attach to your toes to work too hard and hold your toes in an unnatural, elevated position.
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
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. If the deformed toe is very painful, your doctor may recommend that you have a fluid sample withdrawn from the joint with a needle so the fluid can be checked for signs of infection or gout (arthritis from crystal deposits).
Non Surgical Treatment
In many cases, conservative treatment consisting of physical therapy and new shoes with soft, spacious toe boxes is enough to resolve the condition, while in more severe or longstanding cases podiatric surgery may be necessary to correct the deformity. The patient’s doctor may also prescribe some toe exercises that can be done at home to stretch and strengthen the muscles. For example, the individual can gently stretch the toes manually, or use the toes to pick things up off the floor. While watching television or reading, one can put a towel flat under the feet and use the toes to crumple it. The doctor can also prescribe a brace that pushes down on the toes to force them to stretch out their muscles.
Surgical Treatment
There are generally two methods surgeons use to correct hammer toes, they are joint resection (arthroplasty) or bone mending (fusion), and the location where this is performed on the toe depends on where the toe is buckled. Its important to recognize that most of the surgical work involved the joints of the toe, not the joint of the ball of the foot. Sometimes a toe relocation procedure is needed when the joint of the ball of the foot is malaligned (subluxed or dislocated).
Prevention
Custom orthotics paired with a well made shoe can prevent the progression and development of hammertoes. Wearing proper-fitting shoes and custom orthotic devices can provide the support patients need to address muscle/tendon dysfunction. It can Hammer toe also support end stage diseases that result in hammertoe deformities by re-balancing the foot and ankle and controlling the deforming forces.
