Background: Proximal third femur fractures are common fractures seen in community. Till date large numbers of intramedullary and extramedullary implant were used in the treatment of these fractures. These fractures differ significantly from femoral shaft fractures and more proximal femoral fractures in mechanisms, treatment and complications. In 1996 AO group has introduced proximal femoral nail (PFN) for treatment of these fractures. The use of PFN in both these fractures resulted in rotational stability along with union in more anatomic position. Aims & Objective: To prove the advantages of PFN like (1) close reduction of fracture which decreases the blood loss and chance of infection; (2) controlled impaction of the fracture; (3) rotational stability; and (4) load bearing capacity of the implant. Material and Methods: We have done a retrospective study of proximal femur fractures operated with proximal femoral nailing at our institute with follow up of 5 – 36 months. Our study included 30 patients with 8 patients having intertrochanteric fracture and 22 patients having subtrochanteric fracture. Patient was asked to come for follow up on 1, 2, 3 and 6 months from the date of surgery. At each follow up patient was assessed clinically as per Harris Hip score12 and x ray AP/LAT view of hip with femur is taken. Results: It concludes that according to Boyd and Griffith classification type II is the most common variety. In our study excellent to good results noted in 74% patients. All of them performing their routine normal activity well. 5 patients had poor results. Complication rate in our study was much lower. There was only one infection which was known case of diabetes mellitus. Conclusion: The procedure takes less time and the patient can be mobilized fast postoperatively as well after fixation with PFN. PFN should always be considered for management of subtrochanteric fractures in young as well as elderly patients who have multiple pre-existing illnesses. PFN is a closed nailing procedure which achieves a Biological Fracture fixation with minimal blood loss, preserving the fracture hematoma and helping easy healing of the unstable subtrochanteric femoral fracture as well as intertrochanteric fracture.
