Rehabilitation training, such as isometric contraction and other exercises, can be performed on the first day after fixation of the fracture without affecting the fixation. After fracture patients should consult the doctor in time, do not move the patient freely before consulting the doctor, and patients with obvious trauma and bleeding should be bandaged in time. Rehabilitation of fracture has a very important role in preventing complications, promoting fracture healing, preventing joint adhesion and restoring function as early as possible. Early rehabilitation training can play a role in promoting blood circulation in the affected limbs, eliminating swelling and preventing muscle atrophy. In the middle and late stages, the training intensity can be increased appropriately to enhance the patient’s muscle strength, joint mobility and proprioception, and promote the return of normal function. In the process of rehabilitation training, it should not cause obvious pain at the fracture site. If sudden pain or swelling occurs, it is necessary to consult a doctor immediately for examination, as displacement of the fracture may occur. It is recommended that patients carry out rehabilitation training under the guidance of a doctor, so as to avoid re-injury caused by improper self-exercise.
