Corrective loss of the relative apical vertebral rotation (AVR) angle in a 16-year-old female AIS (Lenke V) with Risser 4. The preoperative relative AVR angle was 14.5°, which was calculated from the difference of rotational angles between the pelvis and apical vertebra. The relative AVR angle was corrected to 3.2° after surgery, and a 2.8° loss was measured at the 1.5-year follow-up visit
