Figure 12.4 Intervertebral trauma motions are shown from the time of whiplash with maximal extensions of the lowest cervical levels C6–C7 or C7–T1 (denoted with #). Physiological ranges are shown on all graphs as a baseline from which to evaluate the trauma induced intervertebral rotations. The figure represents the 2.5g trauma class (n=4) in (A), the 4.5g trauma class (n=2) in (B), the 6.5g trauma class (n=4) in (C), and the 8.5g trauma class (n=2) in (D).
