EARLY PROSTHETIC COMPLICATIONS AFTER UNIPOLAR HEMIARTHROPLASTY

Background: In Australia, the most frequently used hemiarthroplasty prosthesis for the management of displaced intracapsular femoral neck fractures is the Uncemented Austin Moore (UAM). Despite concerns regarding poor functional outcomes and increased early revision rates associated with the UAM prosthesis, apprehension regarding the systemic side‐effects of polymethylmethacrylate cement implantation in the elderly patient continues to influence prosthesis selection. This study examines the incidence of early prosthesis related complications after UAM and Cemented Thompson (CT) hemiarthroplasty procedures for the management of femoral neck fractures. Methods: A multicentre retrospective review of charts and radiographs was conducted in 1118 unipolar hemiarthroplasty implantations to determine early complications associated with the CT and UAM prostheses over a 6‐year period in five Queensland public hospitals. Results: Intraoperative periprosthetic fractures were sustained in 11.8% of UAM and 1.8% of CT implantations (P
