The first step after the fracture of the ankle is to improve the local X-ray, and initially determine the displacement of the ankle fracture to determine the treatment plan. If there is no obvious displacement of the ankle fracture, the choice of conservative treatment can be cast immobilization. During the period of cast immobilization, the rehabilitation training method is to carry out active muscle contraction, lifting the leg and bending the knee, and move the toes appropriately to help reduce the swelling. If there is obvious displacement of the fracture of the outer ankle, it is necessary to have timely surgical repositioning and internal fixation after the swelling subsides. Postoperative exercise is mainly to perform early ankle flexion and extension training, in addition to calf muscle contraction, and knee flexion and extension training, which helps to maintain the function of the joint. Avoid early blind weight bearing to prevent fracture displacement and affect fracture healing.
