Abstract:
Objective To study X-ray and CT methods of diagnosis of unilateral dislocation of the lower cervical vertebra(C_(3～7)).Methods 15 cases of the injury of unilateral dislocation of the lower cervical vertebra were reviewed from August 2002 to June 2008,X-ray and CT findings were observed.Results Lateral projection of X-ray showed:the anterior displacement of dislocated vertebra was less than 25% in 15 cases,the distance of posterior border of lateral mass of below vertebral body to line of neural scute changed rapidly in 13 cases,sign of "bow tie" of processus articularis superior in 12 cases.Antero-posterior projection showed that spinal process was lateral deviation.Oblique projection showed that intervertebral joints were dislocation or interlocking. CT showed:the "hamburger" sign were destroyed in 7 cases,fracture of unilateral articular process in 8 cases,rotation of vertebral body of dislocation and its superior vertebral body in 13 cases, "double ring" sign in 12 cases.Conclusion The signs of X-ray and CT in combination with the mechanism of injury and clinical situation,the unilateral dislocation of the lower cervical vertebra can be diagnosed accurately.
