Abstract and keywords

The objective of this study was to make use of recent developments in Computational Fluid Dynamics (CFD) modeling to investigate the pressure phenomena and the hypothesized concomitant vein blood flow that take place in the spinal canal during extension and flexion motion of the cervical spine.
