Posterior-anterior radiograph showed a 71 ° coronal plane deformity with an apex in the intervertebral space of L1 and L2. No significant reduction was found in side-bending image. The thoracic curve can be compensated with a Cobb’s angle of 43°. There is a 10.3 cm distant from the mid-point of superior border of sacrum to the C7 plumb line. This prompted severe coronal imbalance. Lateral radiograph showed sagittal imbalance (6.3 cm) and a 44° thoracolumbar kyphosis (T10-L2)
