Flexion-rotational injuries: jumped and perched facets. (a) Sagittal MDCT image demonstrates anterior “jump” displacement of the inferior articular facet of C6 relative to the superior facet of C7 (white arrow). No associated fracture was present. (b) Sagittal STIR image demonstrates increased signal in the ligamentous structures between C6 and C7 (white arrow) as well as diffusely within the soft tissues (black asterisk). (c) Sagittal MDCT image demonstrates anterior displacement of C5 with “perching” on the inferior facet of C5 and the superior facet of C6 (white arrow). (d) Sagittal STIR image demonstrates cord contusion (black arrow) as well as injury to the posterior ligaments (black asterisk)
