Comparative outcomes of proximal femur intramedullary nailing vs. cemented bipolar hemiarthroplasty for treating intertrochanteric fractures in patients aged 75 and older: analysis of risk factors for postoperative all-cause mortality

In elderly patients aged 75-84 years with intertrochanteric femur fractures, both internal fixation (IF) and long-stemmed cemented hemiarthroplasty (LCHA) are viable treatment options. However, for patients aged 85 years and older, IF is associated with a relatively lower postoperative all-cause mortality rate and should be prioritized as a treatment modality. Additionally, preoperative AST levels may serve as a valuable predictor of postoperative all-cause mortality in elderly patients undergoing surgery for intertrochanteric femur fractures.
