Fractures of the upper arm include the proximal humerus, the humeral stem, and the distal humerus (including the supracondylar and condylar humerus). In clinical practice, we have found that postoperative pain and stiffness in the two adjacent joints (shoulder and elbow) can occur due to pain, injury, or braking, as well as inflammatory response and hematoma from the injury. In this case, it is very difficult for the patient to exercise actively, but without exercise, joint adhesions may occur, which may cause obstacles to the recovery of the joint function in the future. It is very important to restore the function of these two joints initially without aggravating the trauma, so as to establish the foundation for formal functional exercise in the future.
