【摘要】：目的:评估高位腰椎间盘突出症(upper lumbar disc herniation,ULDH)患者的脊柱-骨盆矢状面形态影像学表现,探讨脊柱-骨盆矢状面形态在ULDH发病机制中的意义。方法:选取2007年1月~2016年12月行手术治疗的29例ULDH患者,其中L1/2椎间盘突出9例,L2/3椎间盘突出16例,L1/2和L2/3双节段椎间盘突出4例;正常无椎间盘突出志愿者58例为对照组。ULDH组年龄20~56岁,女10例,男19例;对照组年龄22~56岁,女21例,男37例。两组的年龄、性别、体重指数比较均无统计学差异(P0.05)。在站立位全脊柱正侧位X线片上测量两组的脊柱-骨盆矢状面形态学参数,包括骨盆入射角(pelvic incidence,PI)、骨盆倾斜角(pelvic tilt,PT)、骶骨倾斜角(sacral slope,SS)、胸椎后凸角(thoracic kyphosis,TK)、腰椎前凸角(lumbar lordosis,LL)、胸腰段后凸角(thoracolumbar junctional angle,TLJ)、矢状面平衡(sagittal vertical axis,SVA);ULDH组测量突出节段椎间盘前、后缘高度和椎间盘角度,对照组测量L1/2、L2/3椎间盘;观察两组是否存在滑脱及椎体楔形变,测量滑脱距离及楔形变角度。根据矢状面形态进行Roussouly分型并比较两组间脊柱-骨盆矢状面参数和Roussouly分型结果。结果:ULDH组的PI、PT、SS和LL分别为36.0°±8.8°、12.5°±6.7°、23.4°±9.6°、36.1°±9.1°,明显低于对照组的43.6°±8.6°、15.4°±6.7°、28.0°±9.1°、48.1°±9.0°(P均0.05);ULDH组的TK、TLJ和SVA分别为33.3°±11.0°、17.0°±6.6°、5.6±20.1mm,明显高于对照组的26.7°±12.1°、6.2°±5.8°、-18.2±16.6mm(P均0.05)。ULDH组的L1/2椎间盘前、后缘高度分别为6.1±1.9mm和5.1±2.1mm,明显低于对照组的9.7±1.8mm和8.5±2.4mm(P0.05);L2/3椎间盘前、后缘高度分别为7.1±2.1mm和5.1±2.7mm,明显低于对照组的9.5±1.9mm和8.3±2.6mm(P0.05)。ULDH组L1/2和L2/3椎间盘角度分别为4.9°±3.0°和5.2°±2.9°,明显高于对照组的3.2°±2.7°和3.1°±2.6°(P0.05)。ULDH组中后滑脱患者10例(34.5%),明显高于对照组(0%)(P0.05)。ULDH组后滑脱距离5.3±1.9mm,24例(82.8%)椎间盘突出节段邻近椎体存在明显楔形变(8.7°±2.4°);而对照组仅2例(3.4%)存在腰段椎体楔形变,比例明显低于ULDH组(P0.05)。ULDH组Roussouly分型Ⅰ、Ⅱ、Ⅲ、Ⅳ型所占比例分别为48.3%、31.0%、17.3%和3.4%,对照组分别为10.3%、46.6%、32.8%和10.3%,其中Ⅰ型在ULDH组所占比例明显高于对照组(P0.05),其余分型在两组间无显著性差异(P0.05)。结论:ULDH患者以Roussouly分型Ⅰ型居多,PI较低,且较正常人群相应节段椎间盘高度显著降低、椎间隙角度增加。
[Abstract]:Objective: to evaluate the morphologic features of spinal and pelvic sagittal plane in upper lumbar disc herniation (ULDH) patients with upper lumbar intervertebral disc herniation, and to explore the significance of spinal and pelvic sagittal plane morphology in the pathogenesis of ULDH.There were 58 cases of normal non-disc herniation volunteers. The age of ULDH group was 2056 years old, female group was 10 cases, male was 19 cases, control group was 22 56 years old, female was 21 cases, male was 37 cases.There was no significant difference in age, sex and BMI between the two groups (P 0.05).The spinal and pelvic sagittal morphologic parameters were measured in the standing position of the whole spine on the anteroposterior and lateral radiographs of the two groups.鍖呮嫭楠ㄧ泦鍏ュ皠瑙，
