Comparative Study between Proximal Femoral Nail Anti Rotation and Proximal Femoral Nail Anti Rotation Asian to Assessing Functional Outcome

Introduction: Intertrochanteric fractures are one of the most common fractures around the pelvis and hip joint. Intrerotrochanteric fracture commonly occurs in elderly adult as a result of a simple domestic fall or slippage due to osteoporosis and young adult due to high-energy trauma. In 1990, 26% of all intertrochanteric fractures were reported in Asia, this figure is estimated to 32% in 2025 and 38% in 2050. The main purpose of our study to differentiate functional, radiological, and clinical outcomes of intertrochanteric fracture treated with Proximal Femoral Nail Anti-rotation and Proximal Femoral Nail Anti-rotation Asian. Materials and Methods: This was a randomized prospective study of 68 intertrochanteric fracture patients (34 cases in the PFN group and 34 cases in the PFN A2 group) from February 2022 to April 2024. Data were collected based on the Harris Hip Score questionnaire at 6 weeks, 3 months, and 6 months and data were entered into Microsoft Excel. Demographic data, surgical duration, intraoperative blood loss, union rates, and complications were recorded and compared between both groups. Statistical analysis was done using Statistical Package for the Social Science software version 26. Results: The mean age was 66.2 ± 15.8 in PFNA2 group whereas 63.1 ± 16 years in PFN group. Majority of the patients were male (63.2%) in both groups whereas female constituting 36.8%. Surgical duration and intraoperative blood loss were significantly less in the PFN A2 group, but functional outcome at 6 weeks, 3 months, and 6 months; complications were not significantly different in both groups. Screw cutout noticed in PFN A2 whereas reverse Z effect observed in PFN follow-up cases Conclusion: Our study infer that PFN A2 has significant advantages when compare to conventional PFN like statistically significant less surgical duration and intraoperative blood loss with faster union time with smaller incision. Implant-related complications are lesser in PFN A2 that indicate biomechanical dominance of helical blade device over conventional dual screw system. Keywords: Intertrochanteric fracture, PFN, PFN A2.
