Overview
The ligaments of the ankle hold the ankle bones and joint in position. They protect the ankle joint from abnormal movements especially twisting, turning, and rolling of the foot. A ligament is an elastic structure. Ligaments usually stretch within their limits, and then go back to their normal positions. When a ligament is forced to stretch beyond its normal range, a sprain occurs. A severe sprain causes actual tearing of the elastic fibers.
