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 occurs when there is tearing and damage to the high ankle ligaments. These injuries are much less common than a traditional ankle sprain. What are the signs and symptoms of a high ankle sprain? A high ankle sprain occurs from a twisting or rotational injury. The high ankle sprain also can occur in the setting of an ankle fracture, which means the bones of the ankle are broken. In some cases, the ligament on the inside of the ankle, the deltoid, will be torn. In this event, the energy of the injury passes from the deltoid, through the high ankle ligaments, or syndesmosis, and up the leg through the fibula. This causes the fibula to be broken at a very high level.
