This study was performed to evaluate the results of treating intertrochanteric fracture with proximal femoral nail antirotation (PFNA).

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.

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.

The findings from this study indicate that PFNA is a useful and reliable choice for the treatment of intertrochanteric fracture of the femur.
