“…Relative ROM in axial rotation and lateral bending were significantly influenced by soft tissue injuries whereas those in flexion/ extension were influenced by degeneration of the disk and facet. It is noteworthy that the low eccentricity impacts are associated with greater spinal canal occlusions [38], indicating a greater risk of severe, permanent, and irreversible neurologic impairment. Spinal canal occlusion results, which have been reported elsewhere [38], indicate that the average low eccentricity impact would be expected to result in a mild to moderate extent of SCI while it is unlikely that the high eccentricity impacts would have resulted in SCI.…”

“…High eccentricity impacts likely result in less clinically stable spines, indicating that post-trauma care including immobilization would be vital for patients with these injuries. As described above, an important consideration is that low eccentricity impacts are associated with greater spinal canal occlusions [38]. As lateral flexion injuries of the cervical spine are associated with injuries to the brachial plexus [2][3][4]10], axial loading with high lateral eccentricities may also be associated with injuries to the spinal nerves and/or brachial plexus.…”

“…More recent studies (cadaveric) on the neck evaluated the effects of lateral eccentricity (the perpendicular distance from the axial force to the centre of the spine) on peak loads, kinematics and spinal canal occlusions of sub-axial cervical spine specimens tested in dynamic axial compression 70 , and noted differences in the kinematics, kinetics, and injuries of ex vivo osteoligamentous human cervical spine and surrogate head complexes that were instrumented with simulated musculature relative to specimens that were not instrumented with musculature 71 . Unfortunately, these studies provide no useful leads for investigating the cervical spine in vivo.…”
