There are two different basic classifications of ankle sprains: Anatomic (the level severity of damage to tissues in the ankle) and functional (the level an injury affects a patient’s ability to walk or put weight on the ankle). Grade II ankle sprain – partial tearing of one or several of these ligaments
Bruising and swelling are common signs of a sprained ankle. If there is severe tearing of the ligaments, you might also hear or feel a “pop” when the sprain occurs.
High ankle sprains are the least common of the three sprained ankle types, occurring when the ligaments in the upper portion of the ankle are twisted during rotational movements of the leg and foot.
