颈椎不稳定性损伤的放射学诊断

Radiographic Assessment of Unstable Injury of the Cervical Vertebrae

作者报告87例颈椎不稳定性损伤,并就其放射学诊断问题进行讨论。提出凡存在颈椎中柱损伤者即应视为不稳定性损伤,其主要X线征象包括椎体移位、椎板间或棘突间间隙增宽、椎间隙异常增宽或变窄、关节突关节间隙增宽、椎体后缘连线不连续以及椎管增宽等。作者认为,X线平片检查对于颈椎不稳定性损伤的诊断具有十分重要的价值,多数颈椎不稳者在伤后早期即可被发现。

A total of eighty - seven cases with unstable injury of the cervical vertebrae were reviewed to analyse the radio-graphic diagnosis of this injury. When the middle column is disrupted, the cervical vertebrae should be defined as unstable. Vertebral displacement, increased interlaminar or interspinous distance, wide or narrowed intervertebral space, wide facet joints,disrupted posterior vertebral body line and wide vertebral canal are all considered as signs of instability. Radiographic evaluation is of great importance to diagnosis of unstable injury of the cervical vertebrae, and most cases of instability will be recognized by initial radiography.
