Ankle sprains, in particular the lateral aspect, are very common injuries which can cause severe disability, therefore detailed knowledge of the ankle joint anatomy is important.
Ankle sprains present as either an excessive inversion or eversion sprain.
Ankle sprains have been classified into categories based upon pathology, function and instability. Treatment of ankle sprains depends primarily on the severity of the sprain, and require a lot of care and rehabilitation so the patients is not left with an unstable ankle. This provides stability of the ankle joint. As the ankle joint is classified as a hinge joint, movements are plantarflexion and dorsiflexion only. The ligamentous structure of the ankle joint is composed of the medial collateral ligaments and the lateral collateral ligaments.
