Hemiarthroplasty was first introduced in 1951 by Boron and Sevin and the first series of total shoulder replacements (TSR) was reported in 1974 by Neer.1 The primary indications for the use of these implants have been non-reconstructable fractures and arthritis. The reverse TSR was first introduced in the 1970s, but had minimal clinical success due to poor design. It has since been redesigned and received approval from the US Food and Drug Administration for use in 2003 and now is commonly used for rotator cuff arthropathy, massive rotator cuff tears, arthritis and fractures.2 Bone loss may be encountered in primary and revision surgery. It is a difficult problem to manage and may even be a contraindication to surgery when severe. Bone loss may affect both the glenoid and humeral side of the joint. Multiple studies have shown component loosening and osseous deficiency to be much more common on the glenoid side than the humerus.3-7
