Wei X, et al. - Authors gauged the association among the location, scope, and extent of lumbar disc degeneration and sagittal spinal-pelvic parameters. Findings suggested the spinal-pelvic sagittal morphology to impact the location of lumbar intervertebral disc degeneration. Degeneration in populations with small pelvic incidence (PI) values was exhibited at the L4/5 and L5/S1 discs and that in populations with large PI values was exhibited at the L3/4 and L4/5 discs. Findings suggested a positive association between the sagittal vertical axis (SVA) value and the overall degree of lumbar disc degeneration.
