Functional outcome of intertrochanteric fracture fixed with proximal femoral nail anti-rotation (PFNA2)

Abstract

Introduction: Intertrochanteric fractures are the most common geriatric fractures associated with osteoporosis requiring surgical intervention. For fixation of these fractures, use an intramedullary nail coupled with a dynamic femoral head/neck stabilisation implant. Many classes of nails incorporating a single compression screw, an extramedullary device, or a compression screw coupled with an anti-rotation screw like the proximal femoral nail have become famous for treating unstable fractures. In this study, we studied the outcome of PFNA2 fixation devices. Material and Methods: This is a prospective cohort study of unstable IT fragility fracture of femur treated with PFN A2. All successive patients are diagnosed with unstable intertrochanteric Boyd and Griffin type 2, 3 and 4 fractures of the femur. Results: We found that the average RUSH score at the end of 6 months was 23.8, and the functional outcomes were assessed with HHS with excellent functional outcomes in 20 cases, good in 3 and fair in 2. Complications were varus angulation and infection, one each. Conclusion: PFN A2 has a good functional outcome at the end of 1 year.
