  【摘要】 目的：测量正常成人腰椎矢状面椎体间成角并探讨其影响因素。方法：自2006年1月～2009年1月，在我院体检中心行体检者共672例，获得完整资料者450例，男235例，女215例，平均年龄43岁，利用专用测量软件测量腰椎相邻节段椎体间成角及腰椎曲度（L1～L5椎体间成角）。根据年龄分为青年组、中年组及老年组，观察相邻椎体间成角与年龄、性别及体重之间的关系。结果：腰椎椎体间成角的平均值为：L1-L2，2.52°；L2-L3，5.33°；L3-L4，8.15°；L4-L5，12.11°；L5-S1，20.14°，L1-L5，24.96°。不同性别及体重指数间腰椎曲度差异无统计学意（P＞0.05）；不同年龄组之间腰椎曲度差异有统计学意义（P<0.05）。随着年龄的增加，腰椎曲度逐渐变小，但中年组与老年组腰椎曲度差异无显著性（P＞0.05）。结论：腰椎曲度随着年龄的增加而逐渐减小，但是中年以后变小的腰椎曲度倾向于稳定。

  【Abstract】 Objective：To determine the intervertebral saggital angle and its associate factors of normal lumbar spine in adults.Method：A total of 672 normal adults experienced physical examination from Jan.　2006 to Jan.2009，of these，450 cases'data were complete.There were 235 males and 215 females with the average age of 43.The intervertebral angle from L1 to L5 was determined by using special software.All cases were divided into three groups，young group，middle-aged group and elderly group.The relationship between intervertebral angles and age were reviewed.Result：The average intervertebral angle was L1/2，2.52°；L2/3，5.33°；L3/4，8.15°；L4/5，12.11°；L5/S1，20.14°；L1/L5，24.96°respectively.There were no significant differences between the total lumbar lordosis and the patients′ gender and BMI（P＞0.05）.The total lumbar lordosis in different groups varied significantly（P<0.05）；the elder of age，the less of lumbar lordosis.Conclusion：The lumbar lordosis decreases with age progressing，while after middle-age，the lumbar lordosis tends to be stable rather than decreasing progressively.
