The sagittal diameter of the cervical spinal canal was measured on standard lateral radiographs of 48 consecutive patients with acute whiplash injury. A follow-up was done 12 months after injury.
The purpose of this study was to evaluate the relationship between spinal canal width and chronic symptoms after whiplash injury.
A narrow sagittal diameter of the cervical spinal canal has been correlated with neurologic deficits in degenerative conditions and after fractures. The authors are not aware of previous studies on whiplash patients related to this area.
Forty-eight consecutive patients were evaluated for whiplash trauma after car accidents. Twenty-four patients (12 men and 12 women; mean age, 37 years) had persistent symptoms after 12 months, while 24 patients (12 men and 12 women; mean age, 34 years) were asymptomatic. All measurements were done from standard lateral radiographs with a graphic digitizer connected to a microcomputer. Three anteroposterior and one oblique measurement of the canal were reconstructed for each vertebrae from C2-C6. Multivariate analysis of variance was used to evaluate any association between gender, remaining symptoms at follow-up, and the recorded values of the spinal canal width.
The spinal canal was significantly smaller in the patients with persistent symptoms than in the asymptomatic group. A significant difference also was found between men and women.
Narrow diameter of the cervical spinal canal is unfavorable in patients with whiplash.
对48例连续的急性挥鞭样损伤患者的标准侧位X线片测量颈椎管矢状径。伤后12个月进行随访。
本研究目的是评估挥鞭样损伤后椎管宽度与慢性症状之间的关系。
颈椎管矢状径狭窄与退行性疾病及骨折后的神经功能缺损相关。作者不知道此前有关于此领域的挥鞭样损伤患者的研究。
对48例连续的车祸后挥鞭样损伤患者进行评估。24例患者（12例男性和12例女性；平均年龄37岁）在12个月后仍有持续症状，而24例患者（12例男性和12例女性；平均年龄34岁）无症状。所有测量均通过连接到微型计算机的图形数字化仪从标准侧位X线片上进行。对C2 - C6每个椎体重建椎管的三个前后径测量值和一个斜径测量值。采用多变量方差分析来评估性别、随访时的残留症状与椎管宽度记录值之间的任何关联。
有持续症状的患者椎管明显小于无症状组。男性和女性之间也发现有显著差异。
颈椎管狭窄对挥鞭样损伤患者不利。
