摘　　要：目的：探讨断面和CT腰椎侧隐窝变化规律及其意义.方法：利用30例横断面标本及50例活体CT扫描,观测侧隐窝及其相关结构.结果：断面标本第3～5腰椎侧隐窝矢径（经椎间盘）分别为（7.43±0.52）、（7.34±0.77）、（6.78±0.58）mm,无性差;CT扫描第3～5腰椎侧隐窝矢径（经椎间盘）存在性差,男性分别为（7.05±1.19）、（6.25±0.94）、（6.98±1.30）mm;女性为（7.53±1.37）、（7.05±1.14）、（7.35±1.39）mm;侧隐窝及其相关结构的数值在断面及CT表现趋势基本一致;在断面和CT上,侧隐窝矢径（经椎间盘）与黄韧带厚度的相关关系无统计学意义,但与椎间盘横径、矢径均呈负相关.结论：侧隐窝及其相关结构的数值在断面解剖及CT上表现趋势基本一致,即CT可较好地反映侧隐窝相关结构的情况;侧隐窝毗邻结构的病理变化均可能导致侧隐窝狭窄.Objective： To approach regularity and significance of lateral recess on cross-section and CT. Methods： Thirty consecutive cross-sectional specimens in cadavers and fifty consecutive lateral scout CT scans in patients were studied to observe lateral recess, ligamenta flava, intervertebral disc, etc. Results： On the plane through the upper of the intervertebral disc, sagittal diameters of lateral recess for L3-Lswere （7.43±0.52）, （7.34±0.77）, （6.78±0.58）mm in cadavers, respectively. No statistically significant difference was seen in males and females for the sagittal diameter of lateral recess, but there was a significant sexual difference for it on CT scans. The sagittal diameters of lateral recess were （7.05 ±1.19）, （6.25±0.94）, （6.98±1.30）ram in males, and （7.53±1.37）, （7.05±1.14）, （7.35±1.39）ram in females. On cross-sectional specimens and CT scans, there were the same tendencies in polygrams which were drawn by measurements of the records related to lumbar vertebrar No statistically significant correlation was seen between the sagittal diameter of lateral recess and thickness of the ligamenta flava on cross-sectional specimens and CT scans, but there was a significantly negative correlation with the transverse diameter and sagittal diameter of intervertebral disc. Conclusion： There were the same tendencies in polygrams on cross-sectional specimens and CT scans for measurements of the records related to lumbar vertebrae, so CT can better reflect the lateral recess and adjacent structures. Pathological changes in adjacent structures may result in the lateral recess stenosis.
