Long-term mortality rates in patients with proximal humerus fracture managed acutely with reverse shoulder arthroplasty and hemiarthroplasty

Abstract

Background: Proximal humerus fractures (PHFs) are common in the elderly, often requiring acute arthroplasty, such as reverse shoulder arthroplasty (RSA) or hemiarthroplasty (HA). Understanding long-term mortality trends in these patients is crucial for improving care and informing health economic analyses. Methods: Data from the Australian Orthopaedic Association National Joint Replacement Registry (2004–2022) were analysed. Patients who underwent primary RSA or HA for PHF were included. Mortality rates were calculated using standardised mortality ratios (SMRs) and compared to the general Australian population, with subgroup analyses based on age, gender, body mass index (BMI), and American ..
