This epidemiologic study used the National Inpatient Sample (2011–2017) to quantify trends in hemiarthroplasty, anatomic TSA, and reverse shoulder arthroplasty, then applied linear and Poisson regression to project procedure volumes through 2025, comparing growth trajectories against total hip and knee arthroplasty.
When planning training exposure or resource allocation, recognize that reverse shoulder arthroplasty is no longer a niche salvage procedure — it is the dominant and fastest-growing shoulder arthroplasty by volume, with demand projected to nearly quadruple by 2025; technical proficiency with RSA is now a core competency expectation for graduating fellows and attendings alike.
