Definition. A sprained ankle is an injury that occurs when you roll, twist or turn your ankle in an awkward way. This can stretch or tear the tough bands of tissue (ligaments) that help hold your ankle bones together. Ligaments help stabilize joints, preventing excessive movement. A sprained ankle occurs when the ligaments are forced beyond their normal range of motion. Most sprained ankles involve injuries to the ligaments on the outer side of the ankle. Treatment for a sprained ankle depends on the severity of the injury.
A high ankle sprain is used to describe a particular type of ankle ligament injury. Normally, when someone sustains a sprained ankle, the ligaments that surround the ankle joint are torn. These injuries commonly cause pain and swelling around the ankle. A high ankle sprain occurs when there is an injury to the large ligament above the ankle that joins together the two bones of the lower leg. These two bones, the tibia (shin bone) and fibula, run from the knee down to the ankle.
