Reverse total shoulder arthroplasty is safe and effective in patients ≥90 Years old

This is the authors' abstract. We don't add key points for this paper.

Background: Surgeons may be hesitant to perform reverse total shoulder arthroplasty (rTSA) in elderly patients due to medical complexity, frailty, and possibility of higher rates of complications and mortality. Credence is given to this notion by reports from the hip and knee arthroplasty literature, which show higher rates of postoperative complications and mortality in elderly patients. As such, the purpose of the current study is to analyze outcomes and complications following rTSA in patients ≥90 years old. Methods: All patients ≥90 years old who underwent primary rTSA from 2010 to 2024 were retrospectively identified. Patient demographics and perioperative data were recorded. Range of motion was assessed preoperatively and at 3, 6, and 12 months postoperatively. Postoperative and radiographic complications were identified. Paired student's t-tests were used to compare preoperative to postoperative outcomes. Results: < .05). Two (15.4%) inpatients experienced acute kidney injuries that resolved and 1 (7.7%) patient had an axillary motor nerve palsy during follow-up that resolved. No patients required a blood transfusion. Conclusion: Performing rTSA is safe and effective in patients ≥90 years old. Various preoperative and intraoperative measures can be taken to decrease the risk of complications. Regardless of preoperative independence level, patients and family members should be prepared for the likelihood of rehabilitation and inpatient stay following surgery.
