A novel method has been developed to graphically recreate the 3-D kinematics of the post mortem human subject (PMHS) cervical spine subjected to low-speed, rear-end impacts. Several previous studies have investigated the kinematics of the cervical spine using high-speed x-ray systems. These kinematics have been classified using qualitative expressions such as hyperextension or S-shape and quantitative calculations of facet stretch using motion data obtained from implanted radio-opaque markers. The current study focuses on a new methodology to graphically recreate the 3-D motion of the cervical spine during a rear-end impact event using a combination of high-speed x-ray kinematics data and CT segmentation of the cervical spine. Each cervical vertebra of the PHMS was implanted with two 3 mm diameter radio-opaque markers, allowing for the kinematics of the cervical spine to be captured using high-speed x-rays. The PHMS was then subjected to a series of simulated low-speed, rear-end impacts on a HYGE mini sled. Post testing, CT scans of each PMHS cervical spine were taken at a slice thickness of 1 mm. All cervical vertebrae, including the implanted radio-opaque markers, were individually segmented using MIMICS (Materialise, Ann Arbor, MI). Using a rigid body assumption, the motion of each vertebral body was simulated graphically by applying prescribed motion time histories, based off of the high-speed x-ray kinematics data, to each segmented rigid body of the cervical spine model. Through these procedures, a graphical subject-specific 3-D model of each rear-end impact event was created, allowing for further investigation of rear-end impact kinematics.
