When ankle injury, the degree of injury should be clarified, and different degrees of injury dressing are different, as follows: a. If the ankle swelling is not obvious and is a mild injury, you can use an elastic bandage for dressing. When wrapping, wrap the elastic bandage from the top of the ankle diagonally to the bottom of the figure of eight, around the bottom of the foot for wrapping. Second, if the ankle injury is more serious, accompanied by obvious swelling, generally suggests that there is ligament damage or ligament tears, this time we should use a cast or brace for fixation, fixation time in about six weeks. During this period, the cast should not be removed at will, otherwise it will easily cause poor healing of the ligament, and the lower limb should be elevated during the fixation period to help the swelling of the limb subside.
