Objectives: To assess results of proximal femoral nail in the treatment of peri-trochanteric fracture of femur. Methods: This study included 90 patients of proximal femur fracture admitted in our institute. The patients were informed about the study in all respects and informed consent was obtained from each patient. Results: Results were evaluated using the Harris Hip Score. We had 45(50%) excellent, 31(34.44%) good, 12(17.8%) fair and 2(2.22%) poor results. Conclusion: The Proximal Femoral Nail Can Be Considered The Most Rational Method of Treating Intertrochanteric and Sub-trochanteric Fractures, Especially the Unstable and Reverse Oblique Type. Also the learning curve is relatively less and hence can be performed well by most of the surgeons. Thus we can conclude that the Proximal Femoral Nail is after proper training and technique, a safe and easy implant option for treatment of complex peritrochanteric fractures.
