Radiographs of case 3. (A) Preoperative X-ray films. Left: Preoperative A-P film showed absence of posterior element at T11 level which indicated that laminectomy had been performed. Right: The lateral film showed anterior collapse of T11 vertebral body and local kyphosis of 36°. (B) Immediately postoperative X-ray films: A closing-opening wedge osteotomy at T11 level and T9-L1 pedicle screw instrumentation (CD HORIZON, Medtronic, Minneapolis, MN, USA) and fusion were performed. The kyphotic angle was corrected to 10°. (C) Follow-up X-ray films: Bony fusion was achieved and there was only 2° of correction loss at 3 years follow-up.
