Abstract
BACKGROUND/AIM: This study aimed to scrutinize nationwide utilization trends of shoulder arthroplasty for proximal humerus fractures (PHFs) using a comprehensive national surgical database. MATERIALS AND METHODS: A retrospective study was conducted with 4181 patients who underwent shoulder arthroplasty due to PHF between 2016 and 2022 using national health records. They are grouped as hemiarthroplasty (HA), anatomical total shoulder arthroplasty (TSA), and reverse shoulder arthroplasty (RSA). The patients' demographic data, length of hospital stay, revision histories, transfusion rates, mortality data, trends in arthroplasty methods over the years, the distribution of cases by hospital characteristics and geographical regions were analyzed. RESULTS: Treatment with HA was administered to 22.1% of patients, TSA to 30.2%, and RSA to 47.7%. The lowest revision rate was observed after HA (4.3%), while higher rates were recorded after TSA (7.9%) and RSA (7.4%) (p = 0.019). It was observed that there was a significant increasing trend in RSA rates and a decreasing trend in HA and TSA rates over time (p < 0.001). CONCLUSION: From 2016 to 2022, there appears to have been a significant increase in the utilization of RSA for the arthroplasty treatment of proximal humeral fractures in Türkiye, and it is used more frequently than HA. However, revision rates after RSA are still higher than those after HA. LEVEL OF EVIDENCE: Level III, retrospective cohort study.
