Clinically Relevant Anatomy
[edit | edit source]

An ankle sprain is a common injury in which one or more of the ankle ligaments is torn or partially torn. Inversion ankle sprains are the most common making up 85% of all ankle sprains.  The most commonly torn ankle ligament is the anterior talofibular ligament (ATFL) which is on the lateral aspect of the ankle.  

Mechanism of Injury / Pathological Process
[edit | edit source]

The most common mechanism of injury for an ankle sprain involving the lateral aspect of the ankle (commonly called a lateral ankle sprain or an inversion ankle sprain) is when the foot is forced into a combined movement of plantarflexion and inversion. In this situation the ankle would roll into an outward direction with the foot and toes moving inward toward the midline of the body.  


A less common mechanism of injury involves a forceful eversion movement at the ankle with injury to the very strong deltoid ligament complex.
