Bilateral femoral neck fracture in a child: a 17-year follow-up.

A long-term follow-up of bilateral femoral neck fracture is presented. The patient sustained the injury in a road accident at the age of five. Both fractures were Delbet type III. Three days after the injury, open reduction and internal fixation were performed. A hip spica cast was applied for 8 weeks. Follow-up radiographs show uneventful healing, with no avascular necrosis of the femoral head. The initial shortening of the right proximal femur persisted. The left femur shows extensive remodeling of the femoral head toward valgus. The patient is painless and currently does some sports.
