A broken ankle is medically known as an ankle sprain, and the specific treatment needs to depend on the condition, which can be treated conservatively with braking, cold compresses or plaster immobilization, or with surgical repositioning and immobilization. If it is just a general soft tissue injury, you can apply local ice packs within 24 hours, which can promote the contraction of capillaries in the injured area and reduce the exudation of tissue fluid from the injured tissue, which will help reduce swelling and pain. At the same time, the injured area can be elevated and higher than the heart to help reduce swelling. When the condition stabilizes, the affected limb can be elevated for active activities of the ankle, and when the swelling and pain are significantly reduced, you can gradually get out of bed for exercise. Temporarily reduce long-distance walking and strenuous exercise, more rest and quiet rest, help recovery. If the pain is more severe, can not bear weight to stand, walk, ankle activities are obviously limited, should promptly go to the hospital orthopedic examination, improve the local X-ray examination, to determine whether there is a fracture. If there is a fracture, there is no obvious dislocation, you can choose cast or brace fixation for conservative treatment. If the fracture is obviously dislocated, which may lead to obvious influence on the function of the limb, then it needs to be fixed by surgical restoration in time.
