After a fracture occurs, treatment should be carried out as early as possible, with the ultimate goal of restoring the original function of the fractured part to the greatest possible extent. There are three basic steps in fracture rehabilitation: 1. reset: a fracture is an interruption of the continuity of the bone, and many fractures will be displaced, which is difficult to heal without reset, and even if it is healed, it will produce a deformed healing, so this kind of fracture with obvious displacement should be reset first; 2. fixation: after reset, many fractures are unstable and difficult to maintain a satisfactory position, and need to be fixed. The most common method of external fixation is a cast, or a small splint can be used for fixation. If the fracture cannot be treated satisfactorily by non-surgical treatment, surgery can be performed by using internal fixation or external fixation brace to achieve the purpose of fixation; 3. Functional exercise: If functional exercise is not performed for a long time, muscle atrophy will occur and the joint will be prone to stiffness. Some fractures are recommended to be treated surgically because after a firm fixation, functional exercises can be performed early and the final functional recovery will be more satisfactory. There are three stages of fracture rehabilitation: 1. the early stage of fracture: the bone scab has not yet formed, so you can take braking and fixation, rest while reducing swelling, or carry out functional exercises for non-fixed joints; 2. the middle stage of fracture: the fracture will have some stability at this time, so you can do some functional exercises appropriately, especially the mobility of the joints, so that joint stiffness will not occur easily; 3. the late stage of fracture: when the fracture is basically After the fracture is healed, the strength and intensity of the rehabilitation training should be increased appropriately, which can help restore the muscle strength and joint mobility.
