The early complications of proximal humerus fracture are mainly nerve injury, especially axillary injury, as well as vascular injury and thoracic injury. If the proximal humerus fracture is not treated properly and the functional exercise is not timely, post-traumatic arthritis, biceps tendonitis, and limitation of shoulder joint movement, mainly periarthritis of the shoulder joint referred to as periarthritis, are likely to occur later. Prevention of these sequelae is generally avoided by exercise 2-3 months after the fracture. This is the prime time for functional exercises. For example, wall climbing exercises, specific methods are facing the wall upward and side wall upward, shoulder lift, rotation, adduction, abduction and other functional exercises.
