History

48-year-old male who became quadriplegic following a motor vehicle accident.  Look first at the lateral cervical spine radiograph (Fig 1), then the cervical spine CT, and finally the MR scan.

-病史：患者男，48岁，车祸后四肢瘫痪。颈椎侧位平片、CT、MR。

The lateral cervical spine radiograph shows considerable soft tissue swelling anterior to C5 and a comminuted fracture of C5 with a slight retrolisthesis at C5-6.  Note the wedged appearance of the vertebral body with a triangular fragment anteriorly.  Subtle lucencies overlie the laminae suggesting extension of the fracture into the posterior elements.

-平片：C5前方软组织明显肿胀，C5粉碎性骨折，轻度向后滑脱。椎体呈楔形改变，前缘可见三角形骨折碎片。透明骨折线穿过终板，提示骨折累及后柱。

The CT (Fig 2) demonstrates severe comminution of the vertebral body with retropulsed fragments impinging on the spinal cord.  It also confirms extensive fracturing of the laminae.  Note that the vertebral body fracture has both coronal and sagittal elements to it.

-CT：可见椎体严重粉碎性骨折，骨折碎片向后压迫脊髓。还可见骨折累及终板。提示该椎体骨折受到冠状和矢状的外力。
