A 16-year-old male patient with severe and rigid scoliosis caused by Marfan syndrome. The preoperative Cobb angle of the main curve was 105° and TS was 34 mm. The thoracolumbar kyphosis was 32° (A, B). He underwent posterior surgery from T2 to L3 and the apical region correction was from T6 to T11. After the operation, scoliosis and thoracolumbar kyphosis was corrected to 51°, and 11°, respectively. The coronal plane restored balance (TS = 3.7 mm) (C, D). After two years of follow-up, the correction remains stable and the TS is improved (E, F). TS, trunk shift
