摘　　要：目的观测不同年龄段正常人群骶髂关节间隙宽度的CT解剖学特征,为骶髂关节半脱位的诊断提供依据。方法对480例无骶髂关节病变受检者的骶髂关节CT影像进行观测,分别比较不同年龄、不同性别、不同层面及不同区域的骶髂关节间隙宽度的差异。结果(1)不同年龄段人群的骶髂关节间隙宽度有明显的差异,随着年龄增大,间隙宽度逐渐变窄;(2)女性骶髂关节间隙宽度稍大于男性,差异无统计学意义;(3)不同层面的骶髂关节间隙宽度有明显差异,下部间隙宽度最小;(4)同侧前、中、后3个区域的骶髂关节间隙宽度有明显差异,但同一区域的左侧和右侧无明显差异。结论骶髂关节间隙宽度存在年龄相关性、空间不均匀性和多样性。本研究可为不同年龄人群骶髂关节间隙宽度提供影像解剖学参考。Objective To observe the anatomical characteristics in the CT appearance of normal sacroiliac joint(SIJ)space in different age groups,and to provide basis for diagnosis of SIJ subluxation.Methods The statistical analysis of CT images of normal SIJ space was performed in 480 patients.The differences of SIJ space width in different ages,genders,levels and regions were compared.Results(1)There were significant differences in the widths of SIJ space in different age groups.With the increasing of age,the width of SIJ space decreased gradually.(2)The width of SIJ space in women was slightly greater than that in men,and there was no significant difference between them.(3)There were significant differences in the widths of SIJ space in different transverse levels.The lower part of SIJ had the minimum space width.(4)There were significant differences in the widths of SIJ space in the ipsilateral anterior,middle and posterior regions,while there was no significant difference between the left and right side of the same region.Conclusions The width of SIJ space is age-related,spatial heterogeneity and diversity.This study provides reference for imaging anatomy of sacroiliac joint space width in different age groups.
