Every mile you walk puts tons of stress on each foot. Your feet can handle a heavy load, but too much stress pushes them over their limits. When you pound your feet on hard surfaces playing sports or wear shoes that irritate sensitive tissues, you may develop heel pain, the most common problem affecting the foot and ankle.

Many patients have questions about the hardware that is used in foot and ankle surgery. If you are having foot or ankle surgery, ask your physician if you will need implants like those discussed below.

A hammertoe is a deformity that causes a toe to become bent upward in the middle so it resembles a hammer. This can cause the toe to rub against the top of the shoe or irritate the end of the toe by jamming it into the ground. Hammertoes often occur in conjunction with other toe problems. It is possible to develop corns (calluses) on top of the middle joint of the hammertoe from rubbing against the top of the shoe.

A hammertoe is a deformity of the second, third, or fourth toe. In this condition, the toe is bent at the middle joint, so that it resembles a hammer. Hammertoes typically start as a flexible deformity but if left untreated could potentially develop into a fixed/rigid deformity that may require more aggressive surgery to correct.

A Haglund's deformity is a bump in the back of the heel bone. The Achilles tendon runs over the bump. Patients with a Haglund's deformity may or may not have pain. Sometimes, the pain is caused by shoes rubbing against the bump. At other times it can be part of pain of degeneration in the Achilles tendon due to the pressure placed there. It is not always clear how much of this Achilles tendon problem is due to the Haglund's deformity.

The gastrocnemius and the soleus are two muscles that make up the calf. The gastroc is the larger and more superficial of the two muscles. The soleus is a deeper muscle within the lower leg. The gastroc tendon combines with the soleus tendon to form the Achilles tendon.

A ganglion is a cyst that forms on top of a joint, ligament, or tendon. The cyst is filled with fluid. Because the ganglion is not cancerous and may disappear in time, if you do not have symptoms such as pain, your doctor may recommend observation only to make sure that no unusual changes occur.

Patients with diabetes are prone to major foot problems. This is because the foot expresses many of the underlying effects of diabetes, including neuropathy, vascular disease, and diminished response to infection.

There are 26 bones in the foot, all of which can be fractured. There are different types of fractures. Sometimes a bone breaks but stays in place (non-displaced). Sometimes a bone breaks into two pieces that move apart from one another (displaced). Other types of fractures include a bone that is broken in multiple places (comminuted) and a bone that breaks through the skin after fracturing (open fracture).

Foot drop occurs when the muscles and tendons that flex the foot up are no longer working. Commonly, it is the result of a nerve injury, stroke, or nerve disease (neuropathy). It also can occur after an injury to a muscle or tendon. If a person is unable to flex the foot up when walking, the foot or toes can drag on the ground. This can make walking difficult and lead to frequent falls.
