A girl aged 15 years and 3 months with a Lenke 4B curve. a The main thoracic curve T4–L1 Cobb angle was 90°. Further, C7PL–CSVL was 10 mm toward the right, and clavicle angle was 4°. The triradiate cartilage was closed, and the Risser stage was 4. b Sagittal T5–T12 kyphosis was 7°, lumbar lordosis T12–S1 was 52°, and C7PL–S1 was 5 mm. c, d The angle with standing side bending of the main thoracic curve was 80°, and flexibility was 11.1%. The patient underwent posterior spinal fusion from T2 to L3 with Ponte osteotomy using the rod-link-distraction-reducer (MSDR) system. e After MSDR correction and posterior spinal fusion, the major curve was corrected to 23°. The correction rate was 74.4%, and C7PL–CSVL was − 4 mm. f Further, sagittal T5–T12 kyphosis was 20°, lumbar lordosis T12–S1 was 53°, and C7PL–S1 was 3 mm. g, h At postoperative 2 years, the major curve was corrected to 26°; the correction rate was 71.1%, sagittal T5–T12 kyphosis was 23°, lumbar lordosis T12–S1 was 53°, and C7PL–S1 was − 3 mm. C7PL–CSVL, distance between the plumb line from the centroid of C7 (C7PL) and the central sacral vertical line (CSVL)
