The scoliotic deformity correction percentage was 46.81% \u00b1 12.26% after the initial operation and 45.08% \u00b1 15.53% at the latest follow-up. Compared with the preoperative values, significant improvements were observed in the coronal and sagittal balance early postoperatively and at the latest follow-up (p &lt; 0.05 for all). The average annual amounts of spinal height gained were 15.73 \u00b1 5.95 mm at T1-S1, 8.94 \u00b1 3.94 mm at T1-T12, and 12.02 \u00b1 6.70 mm between the instrumented segments. The total height gained at T1-S1 and T1-T12 was 72.18 \u00b1 28.74 mm and 37.62 \u00b1 12.53 mm, respectively.
