Background: Previous literature has cited age as an independent risk factor for surgical outcomes following total shoulder arthroplasty (TSA). The purpose of this study is to determine the short-term outcomes of nonagenarians following primary TSA and compare them to younger cohorts.
Methods: The Nationwide Readmission Database (NRD) was queried from 2010 to 2020 to identify patients who underwent a primary reverse or anatomic TSA (rTSA or aTSA).
