Video Primer: Ankle Sprains
Lateral Inversion Sprains
Ankle sprains are categorized by the type of motion that causes the injury. The most common type, called a lateral inversion sprain, occurs when the foot rolls inward. This causes injury to the ligaments on the outer side of the ankle, especially the anterior talofibular ligament.
Medial Eversion Sprains
A second type of sprain, called a medial eversion sprain, occurs when the foot rolls outward. This type of sprain causes injury to the ligaments on the inner side of the ankle.
Syndesmosis (High Ankle) Sprains
The least common type of sprain is called a syndesmosis (or “high ankle”) sprain. This type of sprain occurs when the foot rolls outward and the leg turns inward.
