Pelvis anteroposterior radiographs of an intertrochanteric fracture in a male patient in his 70s. (a) Preoperative radiographs show an intertrochanteric fracture (Arbeitsgemeinschaft für Osteosynthesefragen/Orthopedic Trauma Association 31-A2.1). (b) Immediate postoperative radiograph after fixation using proximal femoral nail antirotation showing a fracture gap. (c) The nail broke at the proximal aperture 6.9 months later due to nonunion. Fracture gap is persistent although compared to the immediate post-operation radiograph. (d) Using a chisel we performed a small osteotomy just below the sleeve of the helical blade on the lateral side. (e) The long proximal femoral nail antirotation with lateral notching and dynamization was performed after proximal femoral nail antirotation removal. (f) The radiograph taken 19.8 months after salvage surgery shows no gap, indicating that there is good bone contact, and the fracture has healed
