摘　　要：目的揭示正常成人腰椎椎孔随年龄增长的形态学变化规律。方法对200例受检者进行螺旋CT扫描,测量腰椎椎孔横径和矢径、关节突关节间距、侧隐窝矢径及夹角等参数。按性别、年龄分组进行统计学分析。结果①女性40岁～49岁组L3、L4、L5侧隐窝矢径,较其余各组减小(P<0.05);男性L5侧隐窝夹角在50岁～59岁、60岁～组明显减小(P<0.05),女性则主要表现在30岁～39岁组较大(P<0.05)。②椎孔矢径与侧隐窝前后径及关节突关节间距呈正的直线相关关系。结论①腰椎椎孔的形态学变化受年龄因素影响;②椎孔径线与侧隐窝前后径及关节突关节间距具有相关性。Objective Evaluate the aging induced morphological changes of adult lumbar vertebral foramen. Methods Three-dimensional （3D） CT imaging reconstruction was performed in 200 cases of lumbar spine. The transverse,sagittal diameter of vertebral foramen, diameter between zygapophysial joints,sagittal and angle of lateral recessus were measured by the computer workstation, and then be statistically analyzed grouping with age and sex. Results （1）The sagittal diameter of lateral recessus of L3,L4,L5 in women at 40-49 were significant decreased than any other groups. The angle of lateral recessus in men significantly decreased at 50-59 and 60- groups （P〈0.05） but the women at 30-39 （P〈0.05）. （2）The sagittal diameter of vertebral foramen was positive straight line correlation with the diameter between zygapophysial joints.Coclusion （3）the morphologic changes of lumbar vertebral foramen were affected by age.（4）The diameter of vertebral foramen was correlation with lateral recessus, and the diameter between zygapophysial joints.
