Ankle sprains are one of the most common joint injuries runners experience. The injury can occur when one rolls over a rock, lands off a curb, or steps in a small hole or crack in the road. Usually the sprain is only mild, but on occasion it may seriously injure the ligaments or tendons surrounding the ankle joint. Management of this injury relies on early and accurate diagnosis, as well as an aggressive rehabilitation program directed toward reducing acute symptoms, maintaining ankle stability, and returning the runner to pre-injury functional level.
General Anatomy of the Ankle
The ankle is comprised of three main bones: the talus (from the foot), the fibula and tibia (from the lower leg). The three bones together form a mortise (on the top of the talus), as well as two joint areas (on the inside and outside of the ankle), sometimes called the "gutters". The ankle is surrounded by a capsule, as well as tissue (the synovium) that feed it blood and oxygen.
Some of the more important structures that hold the ankle together are the ankle ligaments.
