OBJECTIVE: The purpose of the study was to define the outcome following retrograde nailing of the femoral shaft. DESIGN: Retrospective clinical study. MATERIALS AND METHODS: Seventeen retrograde intramedullary nailings of the femur were performed in 16 patients for management of complex orthopedic trauma. Thirteen patients were followed for an average of 22.8 months (range from 9 to 72 months). The indications for retrograde nailing were an ipsilateral femoral neck and shaft fracture in eight cases, knee disarticulation or long above knee amputation associated with a femoral shaft fracture in five cases, traumatic arthrotomy of the knee ipsilateral to a shaft fracture in two cases, one case of a shaft fracture ipsilateral to an acetabular fracture that required an extensile exposure, and one case of a femoral nonunion with a knee contracture. In fourteen of the seventeen cases the femur fracture was open including two grade III C injuries. MEASUREMENTS AND MAIN RESULTS: Two patients died in the early postoperative period due to the severity of the initial trauma and one patient was lost to follow-up. The results were generally poor and postoperative complications were common. There were five nonunions in the group, one which required revision to an above knee amputation for an infected nonunion following a grade III open femur fracture. The average range of motion of the knee was 3 degrees to 110 degrees, and two patients had an extensor lag of 5 degrees or more. Six patients underwent removal of hardware through a second arthrotomy with no significant loss of knee function related to the second procedure. CONCLUSIONS: The authors concluded that the high complication rate and poor results were related to the severity of the initial injury. An intercondylar starting can be used in properly selected cases with minimal effect on knee function.
