Clinical and functional outcomes of proximal femoral nailing in proximal femur fractures: a prospective study of 100 cases

Background: Intertrochanteric fractures are common in elderly osteoporotic patients and carry high morbidity and mortality if not treated adequately. Proximal femoral nailing (PFN) has been developed to overcome limitations of extramedullary fixation devices. Objectives were to evaluate functional and radiological outcomes of PFN in proximal femur fractures. Methods: A prospective study of 100 patients with intertrochanteric femur fractures was conducted between March 2022 and July 2024. Patients were treated with PFN and followed up for 6-18 months. Functional outcome was assessed using the Harris hip score (HHS). Results: The mean patient age was 648. years (28-95 years). Left-sided fractures (57%) were more common than right (43%). 68% fractures were unstable (Evan’s classification). Average interval from injury to surgery was 42 days, mean operative time 85 minutes. At one-year follow-up, 66% had excellent, 19% good, 10% fair, and 5% poor outcomes (mean HHS: 8882.). Complications occurred in 15% cases. No non-union was observed. Conclusions: PFN is a reliable fixation method for intertrochanteric fractures, offering stable fixation, early mobilization, and favorable functional outcomes with minimal complications.
