无骨折脱位型颈髓损伤的临床研究

目的：探讨颈椎在无骨折脱位情况下出现颈髓损伤的临床机制。方法：观察２４例无骨折脱位型颈髓损伤，重点分析其影像学检查特点。结果：２７％病例合并椎管狭窄，８３％的病例存在椎间盘突出，不同程度压迫脊髓。结论：无骨折脱位型颈脊髓损伤机制中，存在外伤致颈椎间盘损伤，突出的间盘向后压迫损伤颈髓。颈椎间盘损伤受力机制为屈曲→压缩→过伸。颈椎管狭窄、椎间盘退变等是此类脊髓损伤的病理解剖基础

A clinical study on cervical spinal cord injury without radiographic abnormality

Objective:To investigate the clinical mechanism of the cervical spinal cord injury without radiographic abnormality(CSCIWRA).Method:Twenty four patients with CSCIWRA were included and the radiology informations were analysed in the study.Result:27% patients had spinal canal narrowing,83% patients present with one or multiple protrusive cervical intervertebral discs.Conclusion:The CSCIWRA mainly result from the flexion compression-extension force, the force has the tendency to injury discs and the spinal cord was injuried by the damaged discs.The mechanism of the spinal cord injury also associated with degenerative discs and spinal canal narrowing.
