Peroneal tenosynovitis is an overuse injury to the tendons that run past the back, outside part of the ankle. These tendons travel behind the ankle bone to connect the muscles of the lower leg with the foot, helping with the actions of toe pointing or turning out the sole of the foot. Injury can range from simple tendinitis to subluxation, in which one or both tendons slip out of their normal position. The tendons may also tear in line with the fibers (longitudinal tear) or at times rupture.

What causes anterior ankle impingement?
The ankle joint is primarily composed of two bones, the tibia (shinbone) and a small bone between the shin and the heel, the talus. When the foot is pointed or flexed, the ankle is compressed at the joint. Pain can result if tissue becomes trapped between the bones. Anterior impingement, at the front of the ankle, can occur from a bad or repeated ankle sprain as the ligaments thicken and get pinched between the bones.
What causes arthritis of the midfoot?
In arthritis of the midfoot, the joints of the midfoot can begin to wear out for a variety of reasons. If they are injured by a fall, a twist or a crush accident, progressive degeneration of the joints can begin. Sometimes an individual’s foot anatomy places more pressure on one portion of the foot, causing a joint to wear. In addition, small amounts of loosening of the joints or slight flattening of the foot can begin the degeneration toward arthritis.
