title: The PFNA proximal femur nail in treatment of unstable proximal femur fractures--3 cases of postoperative perforation of the helical blade into the hip joint.
abstract: The proximal femur nail antirotation represents a new generation of intramedullary nailing devices for fixation of stable and unstable trochanteric fractures of the proximal femur. We report 3 cases of postoperative perforation of the helical blade through the femoral head into the hip joint without any signs of rotational or varus displacement of the fracture.
