A sprained ankle is a very common ankle injury which involves the stretching or tearing of the ankle ligaments. The most common is an inversion injury where the ankle turns inward, injuring the ligaments on the outside of the ankle.
The most common injury sustained in a sprained ankle is to the anterior talo-fibula ligament (ATFL) (refer to figure above). If the sprain is severe, there might also be damage to the calcaneo-fibula ligament (CFL) (refer to figure above). In addition to the ligament injury, there may be additional injury to tendons, bone and other joint tissues. It is important to get an accurate diagnosis of your ankle sprain as severe ankle sprains may be associated with a fracture.
