Pathologic (metabolic bone disease or bone lesion), periprosthetic and penetrating traumatic femoral shaft fractures were excluded.\u0000 \u0000 \u0000 \u0000 Patient demographics, mechanisms of injury, treatment methods, and associated injuries were analyzed. Pre-treatment x-rays and CT scans were reviewed for the identification of ipsilateral femoral neck and shaft fractures.\u0000 \u0000 \u0000 \u0000 Among 840 pediatric patients included in the study, 4 patients (0.5%) sustained ipsilateral femoral neck and shaft fractures. All of the femoral neck fractures were observed in adolescents (ages 13-17) and involved in high-energy traumas. In adolescents involved in high-energy trauma, the incidence increased to 1.7%. Pre-treatment sensitivity of both x-rays and CT scans was only 50% for the detetion of femoral neck fractures.\u0000 \u0000 \u0000 \u0000 This study reveals that ipsilateral femoral neck and shaft fractures in pediatric patients are rare, occurring in adolescents involved in high-energy trauma. The findings suggest the need for a selective, rather than routine, use of CT scans based on the patient's age and the mechanism of injury. The use of alternative imaging methods such as MRI should be considered in order to balance diagnostic accuracy while minimizing radiation exposure.\u0000 \u0000 \u0000 \u0000 Prognostic- Level III.
