摘　　要：目的通过对腰椎终板角和椎间隙高度的影像学测量,为腰椎间盘突出的诊治提供理论依据和技术指标。方法根据纳入标准选取符合条件者,异常单间隙组为椎间盘突出患者30例,正常组为健康志愿者30例;进行CT扫描,将原始数据以D ICOM格式导入三维重建软件M im ics 10.01,并测量终板角和椎间隙高度,进行统计分析。结果腰椎正常组与异常组椎间隙前高总体呈渐增趋势,两组最大值均在L4-5,最小值均在L1-2;终板角最大值均在L3-4,最小值均在L5-S1;腰椎终板角和椎间隙的变化没有相关性。结论终板角的大小和椎间隙的高度变化可推断椎间盘突出程度,为临床腰椎间盘突出诊断和评价突出程度提供量化指标。Objective To provide theoretical references and technical indicators for the diagnosis and treatment of lumbar intervertebral disc herniation through imaging measurement of lumbar vertebral end-plate angle and intervertebral space height.Methods The subjects were selected based on the enrolling criteria including 30 patients with lumbar intervertebral disc herniation（abnormal group） and 30 healthy volunteers（normal group）.CT scan was applied and the data were imported to three-dimensional reconstruction software Mimics 10.01 in DICOM format.The end-plate angle and the height of intervertebral space were measured to do statistical analysis.Results The height of pre-intervertebral space was in an overall increasing trend in both groups,maximum values were in L4-5 and minimum values were in L1-2.Maximum values of end-plate angle were in L3-4 and minimum values were in L5-S1.Lumbar intervertebral end-plate angle was not correlated with the changes of intervertebral space height.Conclusion The severity of lumbar intervertebral disc herniation can be inferred by referring to the size of end-plate angle and height of intervertebral space,which provide quantitative indicators for the diagnosis and evaluation in clinics.
