椎间盘退变84例CT分析
【摘要】随着年领的增长,髓核水分和蛋白质含量减少,纤维结缔组织增多;纤维环中水分含量减少,纤维组织透明变性,增粗及排列紊乱,为此及易造成椎间盘膨出、椎间盘突出、椎间盘真空征。CT扫描是诊断腰椎间盘退变的有效检查方法。

【Abstract】along with the year collar growth,the moisture content and the protein content reduces,the textile fiber knot contracts the organization to increase;In the textile fiber link the moisture content reduces,the fiber structure transparent denaturation,increases thick and the arrangement disorder,and is easy for this to create the intervertebral disc to swollen,the intervertebral disc is prominent,the intervertebral disc vacuum drafts. The CT scanning diagnoses the effective inspection method which the waist intervertebral disc draws back changes.

1 资料及方法
本组病例共84例:男性58例,女性26例,年龄44岁一8l岁之间,平均年龄62岁,60岁以上70例,占83%,腰椎68例,颈椎10例,胸椎6例,本组病例全部CT扫描诊断。
2 CT表现
2.1 纤维环向椎体周围膨出,表现为均匀一致的软组织密度影,CT值50-90hu之间,其宽度2-8ram;一般两侧略宽于前缘,后缘最窄,若发生钙化则膨出的软组织中出现弧形高密度影,CT值为160-400hu。本组出现椎间盘膨出52例,99节,颈部33节,胸部10节,腰部56节。
2.2 椎间盘突出并钙化,发生钙化的部位一般在突出物的外缘,是弧形或指压迹样,有的是分节状,也有的突出物完全钙化,本组出现30节,颈椎间盘8节,腰椎间盘22节。 (包括L5一S16节)
2.3 椎间盘膨出或突出伴真空现象。椎间盘真空区形态可多种多样,有单囊形,有多囊形,且大小不等,也有条带形,柳叶形,花瓣形及其它不规则形。CT值一100-500hu之间。本组出现22节,颈部1节,胸部2节,腰骶部19节。
2.4 不管推间盘膨出或突出均可造成①硬膜囊受压变形,移位②神经根淹没、水肿及受压移位。③椎管狭窄,椎管矢状径, 百拇医药(张金海 贾爱华)
