Ankle Sprains

The ankle joint is a flexible hinged joint which consists of three bones (tibia, fibula and talus). Tendons permit up and down movement and, to a small extent, sideways movement. The bones are stabilised and held together by ligaments.

The hinged joint permits a wide range of motion, and is strong enough to bear the weight of the entire body. However, ankles are frequently injured, especially in sporting activity. A sprained ankle occurs when the ligaments in the ankle joint are torn or stretched. Depending upon the amount of damage to the ligament a sprain can be mild, moderate or severe.
