The proximal humerus is the second most common location of primary bone sarcomas and a frequent location of benign locally aggressive primary osseous tumors. In contrast to other locations, tumors in this region impose significant challenges for local control and reconstruction. This is due to glenohumeral joint anatomic characteristics such as lack of intrinsic stability and dependence on dynamic and static stabilizers. In addition, the close proximity of the axillary nerve and axillary vascular bundle places these at risk of resection when attaining local control. Allograft prosthetic composites (APCs) of the proximal humerus are one of the methods for mobile reconstruction. This modality presents lower fracture rates when compared to osteoarticular allografts and lower rates of subluxation and instability than endoprosthesis. Recent literature documents a trend for superior functional outcome at comparable complication rates. APC reconstruction is an important tool in the orthopedic oncologist armamentarium.
