Abstract

The proximal femoral nail anti-rotation (PFNA) is a useful device to fix trochanteric fractures of the proximal femur. We report a case of postoperative penetration of the helical blade through the femoral head into the hip joint without any sign of rotational or varus instability in the fracture.
