Abstract

A patient is presented with a cervical spinal cord transection which occurred after a motor vehicle accident in which the air bag deployed and the seat belt was not in use. The patient had complete quadriplegia below the C5 level and his imaging study showed cervical cord transection at the level of the C5/6 disc space with C5, C6 vertebral bodies and laminar fractures. He underwent a C5 laminectomy and a C4-7 posterior fusion with lateral mass screw fixation. Previous reports have described central cord syndromes occurring in hyperextension injuries, but in adults, acute spinal cord transections have only developed after fracture-dislocations of the spine. A case involving a post-traumatic spinal cord transection without any evidence of radiologic facet dislocations is reported. Also, we propose a combined hyperflexion-hyperextension mechanism to explain this type of injury.

摘要

患者因机动车事故导致颈脊髓横断，事故中安全气囊弹出但未系安全带。患者 C5 以下完全四肢瘫痪，影像学检查显示 C5/6 椎间盘水平的颈脊髓横断，C5、C6 椎体和椎板骨折。他接受了 C5 椎板切除术和 C4-7 后路融合加侧块螺钉固定。先前的报告描述了过伸损伤中的中央脊髓综合征，但在成人中，急性脊髓横断仅在脊柱骨折脱位后发生。报告了一例无放射学关节突脱位证据的创伤性脊髓横断。此外，我们提出了一种复合过屈-过伸机制来解释这种类型的损伤。
