In clinical practice, after a fracture of the proximal humerus occurs and is properly treated, the later stages involve rehabilitation. Before the rehabilitation training, the X-ray film of the proximal humerus must be taken to clearly diagnose that the fracture of the proximal humerus is healing well and there is growth of bone scab before the rehabilitation training can be carried out. The main content of the rehabilitation training is to have the shoulder joint abduction, dorsiflexion, supination, adduction and other movement training. The training should be carried out in a gradual and orderly way. During the rehabilitation training, pain and swelling in the shoulder will occur, and the pain level must be within the limit of one’s tolerance, and it is best to carry out the rehabilitation training under the guidance of the rehabilitation doctor to avoid accidents. Before the rehabilitation training, the shoulder joint should be warmed up and baked by the physiotherapist, in order to promote the smooth blood circulation in the shoulder, and the pain will be reduced during the rehabilitation training.
