Ipsilateral femoral neck and shaft fractures are uncommon and have difficulty in diagnosis. The injury results from high energy trauma. From January, 1990 to March, 1995, 10 cases of ipsilateral femur neck and shaft fractures had been treated. Follow up period varied from 10 months to 3 years (average 1 year 10 month). The purpose of this study is to evaluate the fracture pattern of neck, complications due to delayed operation, and efficient methods of fixation. The neck fractures were minimally displaced or not displaced in 8 cases. The femur shaft fractures were usually comminuted and located at midshaft. The timing of operation was often determined by the patient's status as a multiple trauma victim, but a delay of days to cases, diagnosis was delayed, but there was no complication, like as avascular necrosis and nonunion. There was one case of nonunion of femur shaft, and which was treated with bone graft. We could not find the difference in complication rate among the fixation methods. Anatomic reduction and stable fixation seem to be more important than the method of fixation and timing of operation.
