Segmental evaluation of the surface and radiological deformity after Cotrel-Dubousset (CD) instrumentation for King type II and III. adolescent idiopathic scoliosis (AIS): surgical and etiological implications.
In this paper we report the segmental effects of CD in each of the three planes of deformity (frontal, transverse and sagittal) in 35 children with AIS (King types II and III) treated by Cotrel-Dubousset instrumentation. Patients were examined preoperatively and in follow-up at 8 weeks and one year, and 15 patients were also examined at two years. Back shape was appraised segmentally as angle of trunk inclination (ATI) at each of ten levels by ISIS and the Scoliometer. The radiographs were measured nonsegmentally for Cobb angle, apical vertebral rotation and spinal balance, and segmentally for both vertebral rotation and tilt (frontal and sagittal plane), and in the rib cage for rib-vertebra angles (RVAs).
