Introduction: Present study was conducted to study the modes of injury in Subtrochanteric fractures of femur and to know the outcome of Proximal Femoral Nail in the treatment of Subtrochanteric fractures of femur. Material & Methods: A prospective observational study was conducted on a total of 30 cases of subtrochanteric fractures of femur. All patients were radiographed at an interval of 6 weeks after nailing, till evidence of union. The patient followed up for one year after the surgery at regular interval. Clinically, union of fracture was assessed and also examination for shortening and deformity was done. Functional outcome was assessed based on Modified Harris Hip Score. Results: Out of 30 cases, 24 cases gave history of road traffic accidents and 6 cases gave history of slip and fall. Full range of flexion of hip at 12 weeks post-operative was observed in 80% of cases and about 20% of patients showed minimally limited flexion. On a whole, all the patients had a satisfactory range of movements post operatively. Our study showed 80% of patients showed full range of movements and 20% showed minimally limited movements at 12 weeks post-operative. On a whole the range of knee movements was satisfactory. Conclusion: Proximal Femoral Nail is a relatively easy procedure and a biomechanically stable construct allows early weight bearing. It offers the advantages of high rotational stability of the head-neck fragment, an unreamed implantation technique and the possibility of static or dynamic distal locking. Thus, the Proximal Femoral Nail is a suitable implant for treatment of all Subtrochanteric fractures.
