This is one example video of a sprained ankle. A sprained ankle, or twisted ankle, is the most common type of soft tissue injury. Soft tissue means any tissue in your body that isn’t bone. A minor sprain is when a ligament is stretched or partially torn. In severe sprains the ligament is completely torn. Sometimes the end of the bone to which a ligament is attached can crack or be pulled off. A sprain can be very painful with the pain getting worse when you move your ankle. With a severe sprain you may not be able to put weight on your leg. Learn more about ankle sprain treatment and therapies.
