A study was conducted to determine the Instant Axis of Rotation (IAR) of the cervical spine for flexionextension loads. Six human cervical spines (C2-T1) were procured and mounted in a programmable testing system. IAR coordinates were calculated using vertebral motions. IAR data was analyzed via statistical tests. It was found that the IAR of the normal sub-axial cervical spine lay in the subjacent body near the facet joints during extension and moved towards the center of the subjacent vertebral body during flexion.
