Total Elbow Arthroplasty: A Descriptive Analysis of 170 Patients From a United States Integrated Health Care System.

Total elbow arthroplasty (TEA) can be used, with varying degrees of success, for the treatment of rheumatoid arthritis, osteoarthritis, and distal humerus fractures and their sequelae in elderly patients. Some of the largest studies of TEA have included data from more than 20 years ago and may not reflect the current practice of TEA. We sought to describe a modern cohort of patients who underwent TEA in a United States integrated health care system. All patients aged 18 years and older who underwent primary unilateral TEA from January 1, 2009, through March 31, 2018, were identified to conduct a descriptive study. The patients' characteristics and demographics, including age, body mass index, sex, diabetes status, American Society of Anesthesiologists classification, and surgical indication, were recorded. The crude cumulative revision probability as well as the 90-day postoperative incidence rate of emergency department visit, readmission, and mortality was calculated. A total of 170 patients met our inclusion criteria. The annual procedure volume nearly doubled, from 11 procedures in 2009 to 21 procedures in 2017. The most common indication for TEA was fracture (40.6%), followed by rheumatoid arthritis (36.5%). At 4-year follow up, the crude cumulative revision probability was 9.8% (95% confidence interval, 5.6%-16.9%). Of the 170 patients who underwent TEA, 43 (25.3%) experienced a 90-day emergency department visit, 24 (14.1%) experienced a 90-day readmission, and 2 (1.2%) died within 90 days postoperatively. This cohort of patients who underwent TEA using modern implants showed a notable increase in the volume of TEA over the study period, with more TEAs performed for trauma. The incidence of readmission and emergency department visits following TEA were high in this study. Further studies are needed to better define the current practice of TEA in the community at large.
