目的探讨下颈椎单关节脱位损伤的X线及CT诊断特点.方法 15例下颈椎单关节脱位损伤患者的X线及CT影像进行观察.结果 X线侧位片示:脱位椎体向前移位的距离＜25% 15例;脱位椎下位椎体关节侧块后缘到椎板线的距离突然改变13例;脱位椎体的双侧上关节突"领结"征12例.正位片示:脱位颈椎的棘突脱位侧偏移15例.斜位片示:小关节脱位或交锁5例.CT示:异常的"汉堡包"征7例;合并单侧关节突的骨折8例;脱位椎及上方的椎体旋转13例;脱位椎体和下位椎体的"双环征"12例.结论结合受伤机制、临床表现和X线、CT的特征性征象,能对下颈椎单关节脱位损伤做出正确诊断.

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.
