Reoperation rate, mortality and ambulatory ability after internal fixation versus hemiarthroplasty for unstable intertrochanteric fractures in elderly patients: a study on Korean Hip Fracture Registry

Introduction The treatment of unstable intertrochanteric fracture in elderly patients is challenging and how to treat these patients remains controversial. The purposes of this study were to compare (1) reoperation rate, (2) mortality and (3) the postoperative change of walking ability between patients undergoing internal fixation (IF) and those undergoing bipolar hemiarthroplasty (HA) due to this type of fracture based on the data from the Korean Hip Fracture Registry.
