Proximal humerus reconstruction in orthopedic oncology.

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.
