摘要:

目的 观测成年人正常骶髂关节间隙的CT影像解剖学特征,为骶髂关节半脱位的影像学诊断提供影像解剖学数据。  方法 对56例无骶髂关节病变的受检者的骶髂关节CT影像进行观测:(1)不同性别同一位置骶髂关节间隙的差异;(2)不同水平面上骶髂关节间隙的差异;(3)同一水平面上同侧前、中、后骶髂关节间隙的差异;(4)同一水平面上左右两侧骶髂关节间隙的差异。  结果 (1)骶2第1水平面(S2-1)和骶2第2水平面(S2-2)左后区骶髂关节间隙不同性别之间存在统计学差异(P<0.05);(2)骶1第1水平面至骶3第2水平面(S1-1~S3-2)6个水平面上,同侧骶髂关节前、中、后关节间隙存在统计学差异(P<0.05);(3)右前区中,S1-1水平骶髂关节间隙分别大于S1-2、S2-1、S2-2和S3-2(P<0.05);(4)左中区中,S2-1水平骶髂关节间隙分别大于S1-1、S1-2、S2-2和S3-2(P<0.05);(5)右中区中,S2-1水平骶髂关节间隙分别大于S3-1和S3-2(P<0.05), 且S2-2水平骶髂关节间隙大于S3-2(P<0.05);(6)左后区中,S2-1水平骶髂关节间隙大于S3-2(P<0.05);(7)右后区中,S2-2水平骶髂关节间隙大于S3-2(P<0.05)。  结论 本研究为成年人正常骶髂关节间隙的宽度提供了影像解剖学参考标准。成年人正常骶髂关节间隙在水平面和冠状面上存在一定的影像解剖学差异。

Abstract:

Objective To observe the anatomical characteristics in the CT appearance of normal sacroiliac joint (SIJ) space in adults, and to provide statistics for imaging diagnosis in sacroiliac joint subluxation. Methods The statistical analysis of CT images of normal sacroiliac joint space was performed in 56 patients, with no pathologic change in sacroiliac joint, to observe: ① sex difference of SIJ space in same position; ② difference of SIJ space in 6 transverse levels correlated to sacrum levels; ③ difference of SIJ space among anterior, middle and posterior area in transverse plane; ④ difference of SIJ space between left and right in the transverse plane. Results  ① Sex difference of SIJ space in LP area of S2-1 and S2-2 was statistically significant (P<0.05); ②Difference of SIJ space among anterior, middle and posterior area in the same side of each transverse level (from S1-1 to S3-2) was all statistically significant (P<0.05); ③In RA area, SIJ space in S1-1 was wider than S1-2, S2-1, S2-2 and S3-2, respectively (P<0.05); 4) In LM area, SIJ space in S2-1 was wider than S1-1, S1-2, S2-2 and S3-2, respectively (P<0.05); ④ In RM area, SIJ space in S2-1 was wider than S3-2 and S3-2, respectively (P<0.05); ⑥ In LP area, SIJ space in S2-1 was wider than S3-2 (P<0.05); ⑦ In RP area, SIJ space in S2-2 is wider than S3-2 (P<0.05).    Conclusions    This analysis offers a reference for imaging anatomy of normal sacroiliac joint space in adults. There are imaging anatomic differences in adult’s normal sacroiliac joint space on transverse and coronal plane.
