Proximal femoral nail antirotation versus bipolar hemiarthroplasty for intertrochanteric fractures: a meta-analysis

Introduction Intertrochanteric fractures account for almost half of all hip fractures, with a mortality rate of 15 to 20 % within one year following fracture, primarily in elderly patients aged 65 years old and older. The purpose of this study is to compare the operative time, intraoperative blood loss, intraoperative blood transfusion, hospitalization time, weight-bearing time, Harris Hip Score at 1, 3, 6, 12 months follow-up, and complications after proximal femoral nail antirotation versus bipolar hemiarthroplasty for intertrochanteric fracture in elderly patients based on the published literature of their comparison.Methods We conducted a comprehensive search in the electronic databases such as PubMed, Scopus, and Google Scholar. Original articles up to November 2024 were screened, focusing on retrospective or prospective cohort studies.Results and Discussion The initial search yielded 702 studies. Six cohort studies with a total of 495 participants were assessed. The Proximal Femoral Nail Antirotation (PFNA) showed statistically significant shorter operative time (p = 0.006), lower intraoperative blood loss (p function show_abstract() { $('#abstract1').hide(); $('#abstract2').show(); $('#abstract_expand').hide(); }
