[Differential roentgenological diagnosis of injuries of the lower cervical vertebrae].

On the basis of 14 experiments with simulation of the lower cervical vertebra dislocations on cadavers and human cervical vertebra blocks, combined with stage discography, the authors singled out 3 groups of +disk and ligament structure damages: damage of capsular--ligamentous apparatus of the rear support complex; damage of ligamentous--capsular apparatus and disk; damage of ligamentous-capsular apparatus, frontal longitudinal ligament and total rupture of a disk. Differentiation is made according to the degree of dislocation of vertebra bodies and articular processes. The data are confirmed by the results of discography of 20 patients.
