Internal fixation with locked plating is the current mainstay of treatment for functionally active patients with displaced proximal humerus fractures. Despite the improvement in fixation techniques, a myriad of poor outcomes and surgical complications have continued to remain prevalent, particularly in the presence of osteoporosis. The stability of this implant is achieved at the screw-bone interface and the success of the procedure is highly dependent on the quality of the juxta-articular bone of the humeral head. Assessment of proximal humeral bone quality is an important part of preoperative plan. The purpose of this study was to review characteristics of local bone quality in the proximal humerus to reduce surgical complication risk．
