Short-term adverse event rates and risk factors following total elbow arthroplasty for fracture and arthropathy: a matched analysis of nationally representative data

Abstract Background Total elbow arthroplasty (TEA) is a mainstay treatment for elbow arthropathy and elbow fracture that can relieve pain and restore functional motion. The purpose of this study was to determine the role of surgical indication in the incidence of short-term adverse events and risk factors influencing complications in TEA to treat arthropathy compared to TEA for fracture. Matched cohorts were created to better isolate the impact of the surgical indication. Methods The study identified patients within the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database that underwent TEA to treat arthropathy or fracture from 2010 to 2020. Matched cohorts were created to analyze the incidence of 30 day adverse events and risk factors for complications. Results The study included 599 patients for analysis. The overall incidence of any adverse event was 9.7%. In matched cohorts of 218 patients, the fracture group experienced a higher incidence of overall adverse events (13.8% vs. 6.0% in the arthropathy group, p = 0.009) and postoperative transfusions (9.6% vs. 1.8% in the arthropathy group, p
