What is Influence of Interpersonal Geometrical Variation on Spinal Motion Segment Stiffness: Implications for Patient-Specific Modeling about?
Study Design. A validated fi nite element model of an L3-L4 motion segment is used to analyze the effects of interpersonal differences in geometry on spinal stiffness. Objective. The objective of this study is to determine which of the interpersonal variations of the geometry of the spine have a large effect on spinal stiffness. This will improve patient-specifi c modeling. Summary of Background Data. The parameters that defi ne the geometry of a motion segment are vertebral height, disc height, endplate width, endplate depth, spinous process length, transverse process width, nucleus size, lordosis angle, facet area, facet orientation, and the cross-sectional areas of the ligaments. All these parameters differ between patients. The infl uence of each parameter on spinal stiffness is largely unknown and such knowledge would greatly help in patient-specifi c modeling of the spine. Methods. The range of interpersonal variation of each of the geometric parameters was set at mean ± 2SD (covering 95% of the population). Subsequently, we determined the effect of each of these ranges on the bending stiffness in fl exion, extension, axial rotation, and lateral bending. Results. Disc height
