Note: If the vertebra number is ≤12, it refers to thoracic vertebrae; and if the vertebra number is >12, it represents lumbar vertebrae (i.e., 11 means T11, 13 means L1, and 14 means L2). IS, idiopathic scoliosis; LEV, lower end vertebra; LLD, lower limb discrepancy; TL/L, thoracolumbar/lumbar; UEV, upper end vertebra
