A Randomized Trial Comparing the Outcome of Proximal Femoral Nailing and Proximal Femoral Nailing Antirotation 2 for Unstable Intertrochanteric Femur Fracture.

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.
