The most common way the ankle can be injured is by an ankle sprain. When an ankle is sprained ligaments on the ankle are either stretched, partially torn or completely torn. The most common type of sprain is an inversion injury, where the foot is rotated inward. Ankle sprains can range from mild, to moderate, and severe. Type 1 ankle sprain is a mild sprain. It occurs when the ligaments have been stretched or torn minimally.
