摘要 目的:应用改良的颈椎斜位X线片测量方法测得动态颈神经根管矢状径,确定对诊治神经根型颈椎病有指导意义的X线片测量指标.方法:选取100名成年人动态颈椎斜位X线片,应用ACR-2000i型计算机影像系统行颈椎侧位、双斜位、过屈过伸斜位X线投照.测得椎间孔矢状径(a),同一椎体下缘斜位矢状径(b),并计算神经根管率(a/b).结果:颈椎动态神经根管率的均数:中立位0.37;过屈位0.45;过伸位0.35.标准差为0.06.颈椎动态神经根管比率的95%理想值范围底限为0.30.结论:动态颈神经根管矢状径率≤0.30时应考虑有颈神经根管狭窄;动态颈神经根管矢状径率,是诊断神经根型颈椎病有效和敏感指标,对神经根型颈椎病治疗方案的选择有重要的指导意义. Objective:To study the significance of X-ray in the diagnosis of the cervical spondylot-ic radiculopathy through the oblique dynamic sagittal distance,which was measured by an improved method.Methods:Lateral,double oblique,much extensive and much flexional photographs of the cervical were taken with Kodak com.ACR-2000i computer image system in100adults.The sagittal distance of nerve root canal(a)and the oblique sagittal distance of same vertebra inferior border(b)were measured,then the ratio of cervical nerve root(a /b)was calculated.Results:The mean ratio s of neutrality,over flex-ion and over extension were0.37,0.35,0.45respectively.The standard deviation was0.06.Conclusion:When the ratio is below0.30,it is thought that the nerve root canal is stenosis.The ratio of dynamic nerve root canal is an effective and sensitive index to diagnose the cervical spondylotic radiculopathy and may be useful in the choice of therapy methods.
