摘要
目的 :探讨腰椎峡部裂滑脱动态摄片的临床意义。方法 :对 5 2例有症状的腰椎弓峡部裂滑脱患者分为两组(轻 中度组和重度组 )进行过屈 /过伸、牵引 /负重动态摄片 ,观察水平位移范围与矢状面旋转角度 ,并与正常组 (10例成年男性自愿者 )和无症状组 (8例无症状腰椎峡部裂者 )比较。结果 :正常组与无症状组间无显著性差异 ;轻 中度症状组与重度症状组间有显著性差异 ;无症状组与有症状组间亦有显著性差异。结论 :腰椎峡部裂滑脱患者临床症状的严重程度与动态滑移密切相关 ;常规前屈 /后伸及过伸 /过屈位X线检查未能显示的节段不稳定 ,通过牵引 /负重动态摄片可显示。
Objective:To evaluate the value of dynamic radiography of lumbar spondylolysis and spondylolisthesis.Method:We conducted hyperextension hyperflexion and traction compression dynamic radiography on two groups(mild or moderate and severe symptomatic patients),the displacement and sagittal rotation were observed,and compared with normal group(10 male volunteers) and asymptomatic group(8 cases).Result:There was no difference between volunteers and asymptomatic patients;the displacement and sagittal rotation between mild or moderate and severe symptomatic patients was different obviously;there was obvious difference between asymptomatic and symptomatic patients.Conclusion:The severity of low back symptoms of lumbar spondylolysis and spondylolisthesis is correlated with translatory displacement obviously;Traction compression radiography provides a simple and practical method to diagnose and measure translatory displacdment in segmental instability even conventional flexion extension radiography fails to provoke any abnomal movement.
