A 16-year-old female, AIS, PUMC IId1 type. Preoperative X-ray showed a 39° left lumbar curve and a 20° right thoracic curve and the apex of the lumbar curve was located at L2,3 disc. Preoperative lateral X-ray showed no thoracolumbar kyphosis (A, B). The interspace angle between L4 and L5 was 4°. On the right Bending film, the interspace angle was 9° (C). On the left Bending film, it turned to 0° (D). Anterior correction and fusion was performed, and the fusion level was from T12 to L4. Postoperative films showed a good correction and the interspace angle was improved to 0° (E, F). Three-year post-operative follow-up, the interspace angle increased to 2° with also a good coronal balance(G, H).
