The Treatment of Intertrochanteric Femoral Fracture with Proximal Femoral Nail Antirotation

Abstract

Purpose: This study was performed to evaluate the results of treating intertrochanteric fracture with proximal femoral nail antirotation (PFNA). Materials and Methods: We performed PFNA on 41 intertrochanteric femur fracture patients from May 2008, to August 2010. We analyzed the operation time, blood loss, recovery of ambulatory function, T-score, the tip apex distance (TAD), the sliding distance of the blade, neck-shaft angle, and complications. Results: The mean operation time was 51 minutes and the mean amount of blood loss was 350 ml. The time to ambulation averaged 7.2 days. Thirty-two cases (79%) recovered their previous walking status at 6 months after operation. The average T-score was 3.3 and TAD was 12.3 mm (8.6∼27 mm). 35 cases (87%) achieved acceptable reduction. The average amount of PFNA blade sliding was 3.3 mm. The neck-shaft angle was changed 2.6 degrees varus displacement at the final follow-up. There was one case of nonunion due to tuberculosis infection. Conclusion: The findings from this study indicate that PFNA is a useful and reliable choice for the treatment of intertrochanteric fracture of the femur.
