The macroscopic and microscopic anatomy of the sacroiliac joint from embryonic life until the eighth decade is presented to establish a baseline of normal anatomy for this joint. The literature concerning the anatomy of the joint was reviewed and found to be fragmentary and conflicting, particularly concerning the diarthroidial characteristics of the joint. From fetal life onward, the iliac cartilage surface is fibrocartilaginous, while the sacral surface is hyaline cartilage. Degenerative arthrosis of the joint commences at an early age, affecting the iliac cartilage to a greater extent than its sacral counterpart. These early degenerative changes in the sacroiliac joint may very well be a more common cause of low-back pain than previously thought.
本文展示了从胚胎期到八十岁的骶髂关节的宏观和微观解剖结构，以建立该关节正常解剖结构的基线。对有关该关节解剖结构的文献进行了综述，发现其支离破碎且相互矛盾，尤其是关于该关节的动关节特征。从胎儿期开始，髂骨软骨表面为纤维软骨，而骶骨表面为透明软骨。该关节的退行性关节炎在早年就开始，对髂骨软骨的影响比对骶骨软骨的影响更大。骶髂关节的这些早期退行性变化很可能是导致腰痛的一个比以前认为的更为常见的原因。
