A 15-year-old girl with adolescent idiopathic scoliosis Lenke 5 curve. (A and B) Preoperative posteroanterior and lateral standing radiograph. (C and D) Preoperative bending radiography. (E and F) Three-year postoperative posteroanterior and lateral radiograph. The patient was treated with posterior en-bloc direct vertebral rotation (DVR) with upper instrumented vertebra (UIV) = upper-end vertebra (UEV) + 1.
