What is an Ankle Sprain?
An ankle sprain is a common injury that occurs when one or more of the ligaments in the ankle are stretched or torn. Ligaments are tough, elastic bands of tissue that connect bones to each other and stabilize joints. In the ankle, they help to maintain the joint’s position and control its movements.
An ankle sprain is typically categorized into two main types: inversion and eversion sprains. Inversion sprains, the most common type, occur when the foot rolls inward, overstretching or tearing the ligaments on the outside of the ankle. These include the anterior talofibular, calcaneofibular, and posterior talofibular ligaments. On the other hand, eversion sprains are less frequent and happen when the foot rolls outward, impacting the medial or inner ligaments, particularly the deltoid ligament. The direction of the foot’s movement during the injury largely determines the type of sprain and the specific ligaments affected.
