Fig. 2

15-year-old girl with a main lumbar curve secondary to syringomyelia. The radiographs demonstrate a lumbar curve of 40° and a thoracic curve of 28° (a). Preoperative bending radiograph shows the high flexibility of major lumbar curve and minor thoracic curve (b). Sagittal and axial views of the syrinx (T5-T8) (c). Postoperative posteroanterior and lateral radiographs following posterior selective lumbar fusion from T11 to L4 demonstrate satisfying correction of syringomyelia-associated scoliosis (d). Radiographs made at three years follow-up (e) show that correction outcome had been well maintained
