Review on the 3rd day, 7th day, 14th day, 28th day and 2 months after the fracture, on the 3rd day, mainly observe whether the cast is loose or too tight, review the X-ray to see if there is any displacement of the fracture, and review the X-ray to see if the fracture has been displaced. 7 days or so, the X-ray should be reviewed to see if there is any displacement of the fracture, if the fracture displacement occurs after the local swelling of the soft tissues has subsided, surgery is needed, and once the ankle joint heals abnormally, the ankle joint activities will be restricted and osteoarthritis will easily occur. Once the ankle joint heals abnormally, it will restrict the ankle joint activity, and osteoarthritis will occur easily. Ankle fractures should be treated carefully and cared for. Each review should check the tightness and comfort of the cast.
