Fig. 1Intertrochanteric fracture in a 69-year-old male. (A) The postoperative antero-posterior view of the hip shows a wellreduced trochanteric fracture treated with a proximal femoral nail antirotation. (B) Nonunion and broken nail developed at three months after the first operation. (C) Antero-posterior view of both femurs after exchange nailing.

Fig. 3Subtrochanteric fracture in a 69-year-old woman (A) fixed by a proximal femoral nail antirotation (PFNA). (B) Nonunion and broken nail developed at three months after the first operation. (C) The second operation was performed using a locked plate. A broken distal nail tip remained after removal of the proximal part of the PFNA. (D) Nonunion and hardware failure developed at six weeks after the second operation. (E) Antero-posterior view of the left femur after nailing.
