A representative case of type2. C7 plum line is drowned in each figure. a Preoperative lateral whole-spine standing radiograph showing chin-on-chest deformity and SVA of 70 mm and PI-LL of 0°. b Lateral whole-spine standing radiograph at 2 weeks after the C2-T5 combined anteroposterior corrective fusion showing improvement in chin-on-chest deformity, but the positive SVA (56 mm) remained. c Lateral whole-spine standing radiograph at 4 weeks after the initial surgery showing a recurrent deformity due to distal junctional failure. d Lateral whole-spine standing radiograph at 12 weeks after the surgery. The patient eventually required a fixation extended down to L2. SVA: sagittal vertical axis, PI-LL: pelvic incidence minus lumbar lordosis
