Figure 1
Fifteen-year-old girl with Risser 5 and Sanders 7 presented with Lenke 5CN (Thoracolumbar curve [type 5] with central sacral vertical line [CSVL] medial to apical pedicle [C] with normal kyphosis [N]) adolescent idiopathic scoliosis. (a) Preoperative radiograph shows a Cobb angle of 47.1°. (b) Immediate postoperative erect radiograph with Cobb angle measuring 8.2° (83 % correction). (c) At the 1.5-year follow-up, the deformity corrected to a Cobb angle measuring 7.5° (further 8% correction).
