交感型颈椎病患者颈椎不稳定的X线测量

The measure ment of radiographs of cervical spine instability of sympathetic cervical spondy losis

目的:探讨颈椎过屈、过伸侧位X线片在交感型颈椎病诊断中的应用及意义。方法:应用游标卡尺和测角仪测量了30例交感型颈椎病患者和30例正常人的过屈、过伸侧位X线片,将C2/3、C3/4、C4/5、C5/6角位移和椎体间滑移分别进行统计、分析和对比。结果:在过伸、过屈位片上交感型颈椎病患者与正常人比较,C4/5、C5/6间角位移和C3/4、C4/5、C5/6椎体间滑移显著增大(P<0.05)。结论:交感型颈椎病颈椎不稳定好发于C4/5,其次是C5/6、C3/4节段,过伸、过屈位片角位移和椎体间滑移在交感型颈椎病的诊断中意义更大,根据本组数据可推算出引起交感神经症状颈椎不稳的X线诊断标准。

Objective:To reveal the significance of fu ll flexion and extension lateral radiographs of cervical spine in the diagnosis of sympathetic cervical spondylosis.Method:30cases of sympathetic cervical spondyl osis and30normal persons were investigated.All the full flexion and extension la teral radiographs of cervical spine were measured.The value of angles and shift between each vertebral body were recorded and analyzed.Result:On the full extens ion and flexion radiographs,the angles between C4/5,C5/6and the shift betwe en C3/4,C4/5,C5/6in cervical spondylotic group were markedly increased and significan tly different(P<0.05)from segments of normal person respectively.According to the present instability criterion,7/30cases in the normal group were abnorm al,wh ile5/30cases in the patient group were normal.Conclusion:The radiographic c hang es of sympa-thetic cervical spondylosis occur mostly on C4/5and secondly on C3/ 4and C5/6.The present instablility crite-rion is not suitable for the diagn osis of sympathetic cervical spondylosis.A new diagnosis criterion should be develope d for instability of sympathetic cervical spondylosis.
