Unusual Complication after Intramedullary Nailing of an Intertrochanteric Fracture.

Intramedullary nails have gained popularity for the treatment of intertrochanteric fractures. Cephalic screw cutout, non-union, nail breakage, intraoperative fractures, and peri-implant fractures are complications of these implants and have been well described. This case report describes an unusual complication in an 89-year-old woman presenting with a femoral neck fracture with an intramedullary nail in place without implant failure or non-union after having been successfully treated three years previously for an intertrochanteric fracture.
