title: Spontaneous femoral neck fracture complicating a healed subtrochanteric fracture--a case report.
abstract: A rare case of spontaneous femoral neck fracture complicating a healed subtrochanteric fracture was encountered in an 85-year-old female. The subtrochanteric fracture was caused by a minor trauma with no other combined injury. Patient received close reduction and internal fixation two days later and the fracture healed in three months. Six months after operation, spontaneous ispilateral femoral neck fracture occurred without trauma. Although there were some reports about subcapital fracture or femur neck fracture complication after operation, this is the first case of spontaneous femoral neck fracture after healed subtrochanteric fracture which was treated with a 95 degrees dynamic condylar screw (DCS) and side plate previously without technical error.
