Scoliotic spinal anthropometry

Three-dimensional spinal data were collected from AP and lateral spinal radiographs of 24 female adolescent idiopathic scoliotics. Vertebral body end-plate eccentricity (AP vertebral body width divided by lateral vertebral body width) was measured and found to be minimized at the apex of the scoliotic curve in approximately 70 percent of the subjects. Measurement of end-plate eccentricity is suggested as a possible method for assessment of vertebral body rotation in scoliotic subjects.
