is a Z-shaped deformity caused by dorsal subluxation at the metatarsophalangeal joint. Diagnosis is clinical. Treatment is modification of footwear and/or orthotics. The usual cause is misalignment of the joint surfaces due to a genetic predisposition toward aberrant foot biomechanics and tendon contractures. RA and neurologic disorders such as Charcot-Marie-Tooth disease are other causes.
Hammer toe is most often caused by wearing compressive shoes. It might also be caused by the pressure from a bunion. A bunion is a corn on the top of a toe and a callus on the sole of the foot develop which makes walking painful. A high foot arch may also develop.
The most obvious symptoms of this injury will be the the middle toe joint is permanently bent at an angle. In the beginning movement may still be possible but as time passes and the injury worsens the toe will be locked in place and possible require hammer toe correction surgery to fix. Another key indicator of hammer toe is that a lump or corn will form on top of the toe. The toe joint will be painful and walking can cause severe discomfort. Occasionally a callus may form on the sole of the injured foot. If you see any of these symptoms together or have been enduring pain for some time, seeing a podiatrist should be your next step.
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 If the deformed toe is very painful, your doctor may recommend that you have a fluid sample withdrawn from the joint with a needle so the fluid can be checked for signs of infection or gout (arthritis from crystal deposits).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
Treating hammertoe involves straightening the toe, making tendons in the toes flexible again, and preventing the problem from returning. Some simple treatments include splinting the toe to keep it straight and to stretch the tendons of the foot. Using over-the-counter pads, cushions or straps to decrease discomfort Exercising the toes to relax the foot tendons (a session with a physical therapist may help you get started with foot exercises) Wearing shoes that fit properly and allow toes plenty of room to stretch out.
Any surgery must be carefully considered and approached in a serious manner, as any procedure is serious for the patient. But in most cases the procedure is relatively straight forward. The surgery can be done using local anesthetic and does not require hospitalization. The patient goes home in a special post-operative shoe or a regular sandal, and in most cases can walk immediately. That's not to say that the patient is walking or functioning normally immediately after the procedure. The patient must take some time off work to rest the foot and allow it to heal.
