If a humerus fracture is treated conservatively, the first step is to wear an external fixation brace or a plaster cast for 4-6 weeks, and then go to the hospital for a review. If there is no obvious problem, passive elbow joint, as well as shoulder joint flexion, extension, abduction, rotation and other functional exercises can be carried out. At the same time, active flexion and extension activities, as well as functional activities such as rotation, should be combined. If surgical treatment is required, one week after surgery, if the broken end is found to be relatively stable during surgery, appropriate passive functional exercises can be performed, again focusing on flexion, extension, and rotation activities. If there are no obvious problems at this time, active flexion and extension, as well as rotational functional exercises can also be combined, which will have a certain benefit for the later functional rehabilitation.
