Distances between the weighted center and the geometric center of nucleus pulposus by axis and Pfirrmann grade. The distance on the longitudinal axis in Grade II discs was significantly larger than that in Grade I discs (p = 0.035). The distance on the axis perpendicular to the longitudinal axis in Grade III discs was significantly larger than that in Grade I and Grade II discs (P < 0.01)
