摘　　要：目的研究正常人群腰椎间关节与矢、冠状面角度及腰椎退行性滑脱与椎间小关节角度关系.方法采用CT扫描.正常组:测量100例正常人腰椎小关节与冠状面的角度,每10岁为一年龄组,男女性别各区分5组;腰椎滑脱组39例,均为L4椎体Ⅰ°滑脱;腰椎间小关节偏矢状位无明确腰椎滑脱患者5例.结果 (1)正常组相同腰椎节段不同年龄组之间椎间小关节与冠状面所成角度差异无显著性(P>0.05).(2)正常组相同腰椎节段椎间小关节与冠状面所成角度男女之间差异无显著性(P>0.05).(3)正常组椎间小关节与冠状面的角度大小与腰椎的节段呈负相关,从L1-2至L5-S1水平,椎间小关节与冠状面角度有逐渐减小或与矢状面的角度有逐渐增大的趋势.结论正常人L1-2～L3-4椎间小关节角度偏矢状面,L4-5～L5-S1椎间小关节角度更偏冠状面;成年人腰椎间小关节角度不随年龄的变化而变化;椎间小关节偏矢状面与腰椎退行性滑脱相关.Objective To study angle of coronal or sagittal articular orientation of the facet joint of lumbar spine in normal person and degenerative spondylolisthesis patients. Methods The facet joint of lumbar spine of 100 controls persons, 39 degenerative spondylolisthesis patients and 5 cases of the facet joint sagittal alignment without spondylolisthesis were measured with CT. Results （ 1 ） There was no significant difference about coronal angle of the facet joint among different age groups（ P 〉 0. 05 ）. （2） There was no significant difference about coronal angle of the facet joint between male and female group （ P 〉 0. 05 ）. （ 3 ） There was negative correlation between coronal angle of the facet joint and level of lumbar spine. From L1 to L5, coronal angle of the facet joint gradually reduced and sagittal angle of the facet joint gradually enlarged （ P 〈 0. 05 ）. Conclusion Angle of the facet joint tend to sagittal plane in L1-2 ～ L3-4 and coronal plane in L4-5 ～ L5-S1. The facet joint sagittal alignment may be the critical risk factor of degenerative spondylolisthesis.
