Registry-based cohort study using The New Zealand Joint Registry (1999–2010) comparing functional outcomes, revision rates, and mortality between RSA (n=55) and hemiarthroplasty (n=313) for acute proximal humeral fractures requiring prosthetic reconstruction.
When selecting between RSA and hemiarthroplasty for a complex proximal humeral fracture requiring arthroplasty, anticipate equivalent early recovery but meaningfully better 5-year function with RSA — and recognize that this functional advantage carries an added benefit of lower expected revision risk based on the OSS-revision relationship established in joint registry data.
