Abstract

Globally, the proportion of reverse total shoulder arthroplasty (RTSA) is on the rise compared to the anatomic total should replacement and hemiarthroplasty. Historically performed as a salvage surgery for cuff tear arthropathy, the indications for RTSA have now expanded over the years owing to an evolution in implant designs and the application of biomechanics in the shoulder joint. The indications for reverse polarity prosthesis have expanded from the earlier cuff tear arthropathy to included a wide range of noncuff related indications as well. The goal of this brief overview is to walk readers through the growing list of RTSA indications. The indications for RTSA are ever increasing due to its peculiar design, biomechanical advantages, and relatively good functional outcome. Off-label indications are expanding and the avenue is yet to be completely explored.
