Figure 3

Simulated coronal correction + derotation of vertebrae using the 3D segmented spine model. A “reference plane” defined as a plane including three points: one at the central notch of the lamina and two at the upper and lower endplates on the posterior vertebral wall (A) was determined for each vertebra from T1-L5. Then, the intervertebral axis, defined as the line intersecting the neighboring reference planes, was determined (B and C). Finally, the correction of each vertebral body was performed by rotating the vertebra around the intervertebral axis until the neighboring vertebral reference planes became matched on the same plane (B and D).
