We treated 10 patients who had femoral trochanteric fractures with AO small proximal femoral nail (PFN). PFN is a new intramedullary device with lag screw and hip pin. One patient showed varus deformity by more than 10 degrees, but there were nocut outs. All patients achieved bony union within 11 weeks. Eighty percent of the patients regained almost the same gait ability after operation. We conclude that this new implant PFN is suitable for the treatment of femoral trochanteric fractures.
