In case of ankle fracture, elevating the affected limb can be divided into continuous elevation and intermittent elevation. If the affected limb is continuously elevated, it takes about 3-4 weeks because the soft tissue damage around the ankle is more serious, swelling and pain are also more powerful, and the blood circulation of the ankle is not as good as the other parts of the limb, so the blood transportation is relatively poor. Promote venous reflux and speed up the swelling and pain. In addition, after the fracture is clinically healed and you need to walk on the ground and do functional exercises, you should continue to elevate the affected limb, intermittently elevate the affected limb, after walking for a period of time, the swelling of the ankle increases, you must stop putting weight on the ground, you must lie on the bed and elevate the affected limb, promote the swelling to subside and then continue to walk and do functional exercises, intermittently elevate the affected limb until you walk on the ground without swelling, you need to do functional exercises for 1-2 months. It takes about 1-2 months for functional exercise.
