ABSTRACT: Introduction: Intertrochanteric fractures are one of the most common fractures encountered among the people above 55 ages. Although life expectancy has increased but patient has more occurrence of fractures. Both surgical and conservative option are the management of intertrochanteric fractures. PFN have intramedullary nail which consists of one lag screw and other one as antirotational screw. While PFNA2 consists of intramedullary nail and only one screw also known as blade. This study focuses on functional and clinical results of intertrochanteric fractures treated with PFN and PFNA2. Materials and Methods: 40 Patients were selected for the Comparative, Prospective and randomized study which was conducted at Janaki Medical College and Teaching Hospital, Janakpurdham, Nepal between September 2022-September 2024. After fulfilling the inclusion criteria, the patients were divided into two groups randomly, with 20 cases in each group. Results: This Study showed PFNA2 has better outcome, and less complication compared with PFN in aspect of blood loss, operative time, radiation exposure and hospital stay. Complications like backing out of screws (z effect and reverse z effect), are not seen with PFNA2. Conclusion: PFNA2 is better implant in terms of intraoperative complications, blood loss, union rates and functional outcome.
