Abstract
BACKGROUND: Proximal Femoral Nailing (PFN) and Proximal Femoral Nailing Anti-rotation (PFNA 2) are both intra-medullary implants having 6 degrees of proximal valgus angulation. The helical blade compact the cancellous bone in femoral head when it is driven inside. AIMS AND OBJECTIVES: 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 2. MATERIALS AND 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 cases (5.26%) and poor in1 case (2.63%). In PFNA 2 group, Harris hip score was excellent in 24cases (63.15%), Good in13 cases (34.21 %), Fair in 1 case (2.63%) and Poor in none of the cases. CONCLUSION: PFNA 2 significantly reduces the operative time and blood loss compared to PFN. However Both PFN and PFNA 2 implants offers no statistically significant advantages over each other in terms of fracture unions, functional and radiological outcomes, post-operative complications and recovery outcomes.
