Fractures of the femoral neck in children are relatively rare and often occur as a result of high-energy trauma. Complications are common due to unreliable blood supply to the femoral epiphysis and epiphyseal plate. Ischemic necrosis is the main cause of poor prognosis in pediatric femoral neck fractures. The risk of developing ischemic necrosis of the femoral epiphysis is related to the type of fracture, and generally the closer the fracture is to the proximal femoral epiphysis, the more likely it is to result in ischemic necrosis of the femoral epiphysis. Ischemic necrosis of the femoral epiphysis takes 12 months or more to manifest, so it is recommended to review the films every 3-6 months, and high quality anteroposterior and lateral frog x-rays are still recommended for review 2 years after the injury. For epiphyseal necrosis that has occurred, osteotomy is recommended to improve inclusion. Additional vascularized bone flap grafting and central decompression are also good methods. Early anatomic repositioning and internal fixation with 4-6 weeks hip herringbone cast fixation is the best treatment for femoral neck fractures, with hollow screws and smooth kerf pins as options for internal fixation. Postoperative complications of femoral neck fracture include hip inversion, premature closure of the epiphyseal plate, and bone discontinuity, in addition to ischemic necrosis of the femoral epiphysis.
