The ankle is a complex joint that connects the foot to the lower leg. It is actually comprised of two joints: the true ankle joint (upper ankle joint) and the subtalar joint (lower ankle joint). With compressive forces in each ankle reaching 7 times our body weight while we do nothing more than walk, the ankle joint is required to withstand more stress than any other joint in the body. Our ankles enable bipedalisn (walking upright on two legs) and a normal gait. The upper ankle joint is comprised of 3 bones: the tibia, the fibula, and the talus. The upper ankle joint's range of motion is defined by the malleoli (the bony prominences on each side of the ankle) and the talus.






Osteoarthritis (degenerative arthritis) is a general term used to describe signs of wear and tear in any of our joints. Various factors may contribute to this wear and tear. Just as the term stomach ache reveals nothing about the specific cause of the ache, the term osteoarthritis should not be construed as a particular cause of joint degeneration about which nothing can be done. If your doctor succeeds in identifying a factor that is contributing to the progression of your osteoarthritis (e.g. axial displacement, a floating joint fragment, or a ligament injury), then it is clear that eliminating this factor will lead to a real improvement in the course of the disease.
Most injuries to the ankle are the consequences of traumatic events such as sports injuries in tennis, skiing or playing soccer. Often enough, however, a simple "overflow" of the foot. Sometimes, even the slippage, for example, from the curb to see a band to cause injury.
