Figure 8

Illustrative example of a patient’s spinal shape in Group 4. ‘x’ = each of six landmarks (vertebral endplate centers and bases of pedicles) on each of 17 vertebrae (omitted from axial view for clarity). Solid line: a smoothed line fitted to the positions of landmarks at vertebral endplate centers. This spinal shape was classified as Group 4 because the combination of left upper scoliosis curve with kyphosis, and right lower curve with kyphosis provided the negative and positive rotations of the two planes of maximum curvature in the two respective scoliosis curve regions.
