  • Abstract
  • Look Inside
  • Reference

 Proximal Femoral Nail Antirotation (PFNA;SYNTHES, Inc.) has been used at our hospital to treat all cases of femoral trochanteric fracture since February 2006. Although no cut-out or secondary fractures were observed in 207 cases, a rare complication, perforation of the femoral head, developed in 2 cases. In both cases it occurred one month postoperativly, and central transposition of the blade had occurred in response to a load such as walk training, and that appeared to lead to perforation of the femoral head. To prevent the development and progression of complications, it is advisable to exercise care in regard to the insertion point and blade length and to conduct careful image evaluations until bone union is achieved.
