Prior subacromial decompression is a significant risk factor for development of acromial stress fracture after reverse total shoulder arthroplasty

This study represents one of the largest cohorts of ASFs to date and is the first database study specifically investigating prior SAD as an independent risk factor for ASF after rTSA. Our results support that prior SAD is indeed an independent risk factor for ASF after rTSA. Further high quality, multicenter studies investigating prior SAD as a risk factor for ASF following rTSA are needed as our results supplement a sparse compendium of literature with mixed results pertaining to the hazard that SAD poses for development of this rare complication.
