The potential indications of SRS-Schwab Grade 6 osteotomy were analyzed. The coronal Cobb angle, segmental kyphosis (SK), deformity angular ratio (DAR), coronal balance, and sagittal vertical axis (SVA) were measured in the preoperative, postoperative, and final follow-up.

The indications of SRS-Schwab Grade 6 osteotomy were as follows: multiple \u201cpushed-out\u201d hemivertebrae (13, 76.5%) and multilevel anterior block (4, 23.5%). Compared with preoperation, the coronal Cobb angle, SK and SVA at postoperation were significantly improved (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u00a0&lt;\u00a0.05 for all).
