Abstract
Different vertebral facet angles in pediatric versus adult necks may explain their disparate biomechanical tolerance and motion under physical loading. We analyzed CT scans of the neck using novel semi-automated image processing software algorithms to characterize the morphology of each cervical vertebra, including precise measurement of facet angle relative to other vertebral landmarks. We observe clear and very significant changes in facet angle with aging for C2 through C7. These findings are useful, when analyzed in conjunction with vehicle crash and injury data, to identify occupant specific factors that may contribute to motor vehicle crash injury tolerance in live subjects.
