Between the ages of 12 and 18 years apophyseal elements appear within the SI joints which fuse subsequently with the sacrum. These apophyses could be demonstrated during two autopsies on juveniles and were seen in 7 CT examinations of patients between the ages of 15 and 19. On CT they appeared as narrow, round or band-like opacities situated on the ventral aspect of the joint. The differentiation of these normal findings from pathological changes within the SI joints is discussed.
在12至18岁之间，骶髂关节内出现骨骺成分，随后与骶骨融合。这些骨骺在两例青少年尸检中得到证实，并在7例年龄在15至19岁患者的CT检查中被发现。在CT上，它们表现为位于关节腹侧的狭窄、圆形或带状不透光区。文中讨论了如何将这些正常表现与骶髂关节的病理变化区分开来。
