退变性腰椎侧凸两侧椎间高度及关节突矢状角参数特点及其对侧凸的影响

目的:分析退变性腰椎侧凸骨性结构参数的特点及其与椎间盘-终板退变的相关性,探讨骨性结构参数对腰椎侧凸发生、发展的影响及意义。方法:选取120例原发性退变性腰椎侧凸患者的影像学资料作为病例组,同时期、同年龄段及同性别比例诊断为腰椎退变性疾病(除外腰椎侧凸)的89例患者的影像学资料作为对照组。分别测量两组患者椎体和椎间两侧高度及两侧关节突矢状角,计算椎体和两侧椎间平均高度及两侧关节突平均矢状角作为骨性结构参数。测量病例组患者的腰椎侧凸角及前凸角。采用pffirman及Modic分级评分法对各个椎间盘及邻近终板退变程度进行量化。比较两组的骨性结构参数,分析骨性结构参数与椎间盘-终板退变、腰椎侧凸角及前凸角的关系。结果:病例组凸凹侧骨性结构参数有显著性差异(P<0.05),呈不对称分布;对照组两侧骨性结构参数无显著性差异(P>0.05);两组间椎间盘-终板退变评分有显著性差异(P<0.05)。相关性分析显示,骨性结构参数不对称度与椎间盘-终板退变评分有相关性(P<0.05),与腰椎侧凸角呈正相关(0

Feature of bony structural parameters and their effect on degenerative lumbar scoliosis

Objective:To investigate the relationship between intervertebral disc-endplate degeneration and bony structural parameters and the effect of bony structural parameters on the development of degenerative lumbar scoliosis.Method:The imaging data of 120 patients with primary degenerative lumbar scoliosis in our hospital were retrospectively reviewed as case group,while 89 patients with lumbar degenerative disease and without lumbar scoliosis were selected as control group.The vertebral body and intervertebral ...
