Ankle sprains occur frequently in daily life, but often because of the early or first sprains do not give adequate attention to the chronic ankle instability or ligament injury is difficult to heal, therefore, foot and ankle surgeons recommend that after acute sprains of the ankle joint should be treated with the “RICE principle”, i.e., rest, ice, compression, and elevation of the affected limb. Elevation of the affected limb Rest: After ankle sprain, one should stop exercising immediately and take X-rays routinely. If there is a fracture, one should decide whether or not to operate according to the displacement of the fracture. If there is no fracture, the affected limb should be immobilized with plaster or ankle brace for about 4 weeks to facilitate ligament and soft tissue healing. Ice: Apply ice or cold packs to the affected limb within 48 hours of the sprain to stimulate vasoconstriction and reduce bleeding and oozing, so as to reduce pain and swelling at the site of the sprain. Compression: Apply moderate pressure with elastic bandage or splint to reduce oozing and help ligament repair. Elevate the affected limb: Elevating the affected limb above the heart can promote blood return and help the swelling to subside.
