Standing whole length X-ray films at 2 years after operation. The A-P film (left side) shows her main thoracolumbar (TL) Cobb is 19.5° while lumbosacral (LS) Cobb is 16.7°. Pelvic tilt (Pt) angle is 7.0° while L5 tile (L5t) angle is 10.8°. Coronal balance (CB) means the distance between C7 centre point to CSVL line (yellow plumb dashed). Its value is 4.0 cm that means radiographic coronal imbalance. However, when we draw the modified CSVL (red dashed) based on the connect line of bilateral iliac highest point (white solid line), measure the distance between C7 centre point to modified CSVL and find the modified coronal balance (modified CB) is 0.6 cm (< 2 cm) which means coronal balance. The lateral film (right side) shows her sagittal balance is well maintained at this time
