               Abstract
               Proximal humeral reconstructive options following radical resection of proximal humeral primary and metastatic
               bone malignancies have evolved over time. With the relatively recent advent of the reverse total shoulder (RTSA),
               this technique has been increasingly employed in this setting over hemiarthroplasty techniques. An array of
               options, including proximal humeral allograft-prosthetic composites (including both RTSA and hemiarthroplasty),
               megaprostheses, and osteoarticular allografts, is reviewed from the perspective of their indications, techniques,
               complications, and published results. An extensive case-based pictorial presentation illustrates these options.

               INTRODUCTION
                                                                                    [1,2]
               The proximal humerus is a common site for metastatic and primary bone tumors . With the evolution of
               chemotherapeutics, radiotherapy, and advanced imaging techniques, limb salvage surgery has become the
               norm in this location except for very advanced cases. Tumors in this region impose significant challenges
               for local control, reconstruction, and function. Potential glenohumeral joint involvement and close
               proximity of neurovascular structures affects local control and function, while lack of intrinsic stability and
               dependence on dynamic and static stabilizers affects reconstruction and function. Resection for metastatic
               disease may require bone-only resection, but restoration of soft-tissue attachments and glenohumeral
