Background: Proximal Femoral Nailing (PFN) and Proximal Femoral Nailing Anti-rotation (PFNA II) are both intramedullary implants having 6 degrees of proximal valgus angulation. The helical blade compacts the cancellous bone in femoral head when it is driven inside. Aim: The aim of our study is to compare radiological and functional outcome and superiority over other in management of unstable intertrochanteric fracture by PFN and PFNA II. Methods: The study was conducted from october 2021 to september 2022 which included 76 patients of unstable Intertrochanteric fractures of femur. Results: In PFN group, Harris hip score was Excellent in 23 cases (60.52%), Good in 12 cases (31.57%), Fair in 2 case (5.26%) and poor in 1 case (2.63%). In PFNA II group, Harris hip score was excellent in 24 cases (63.15%), Good in 13 cases (34.21 %), Fair in 1 case (2.63%) and Poor in none of the cases. Conclusions: PFNA II significantly reduces the operative time and blood loss compared to PFN. However Both PFN and PFNA II implants offers no significant advantages over each other in terms of fracture unions, functional and radiological outcomes, post-operative complications and recovery outcomes.
