FUNCTIONAL AND RADIOLOGICAL OUTCOMES OF PROXIMAL FEMORAL NAILING VERSUS DYNAMIC HIP SCREW IN INTERTROCHANTERIC FEMUR FRACTURES

Abstract

Background: Intertrochanteric femur fractures are common orthopedic injuries associated with significant morbidity, particularly among elderly individuals. Early mobilization and stable fixation are essential for reducing complications and restoring functional independence. Proximal Femoral Nailing (PFN) and Dynamic Hip Screw (DHS) are commonly used fixation methods for these fractures. Aim: To compare the functional and radiological outcomes of PFN and DHS fixation in intertrochanteric femur fractures. Materials and Methods: This prospective observational study was conducted at Dindigul Medical College from 2025 to 2026 over a period of one year. A total of 120 patients aged between 50 and 60 years with intertrochanteric femur fractures were included. Patients were divided into two groups: PFN group (n=60) and DHS group (n=60). Functional outcome was assessed using the Harris Hip Score (HHS), while radiological outcome was evaluated based on fracture union and postoperative complications. Results: The PFN group demonstrated significantly shorter operative duration (68 ± 12 min vs 92 ± 15 min), lower intraoperative blood loss (120 ± 35 mL vs 240 ± 50 mL), and shorter hospital stay compared to the DHS group. Mean fracture union time was earlier in the PFN group (14.2 ± 2.1 weeks) than in the DHS group (16.8 ± 2.6 weeks). Excellent-to-good functional outcomes were more frequently observed in patients treated with PFN. Delayed union and implant-related complications were comparatively higher in the DHS group. Conclusion: PFN provides superior functional recovery, earlier radiological union, reduced operative morbidity, and fewer postoperative complications compared to DHS fixation in intertrochanteric femur fractures.
