Lumbosacral and Spinopelvic Anatomy and Pathology - Sacroliliac Joint

Axial Section through the Sacroiliac (SI)

Axial section through the sacroiliac joints of a 29-year OD female
Axial section through the sacroiliac (SI) joints of a 29–year–old female (same case as depicted in slides 13 and 14, also in the following slides 16 through 18). The section is carried through the level of S2–S3 where the vestige of the S2–S3 disc is seen. Anterior to the sacrum the visceral contents of the lesser pelvis are seen. The asymmetry of the SI joints is caused by the slightly oblique orientation of the specimen in the cryomicrotome. The nerves of the lumbosacral trunk are embedded in the thick retroperitoneal body of fat. The constituents of the sciatic nerve run in close proximity of the anterior aspect of the SI joints. The subchondrat bone and the hyaline cartilage of the sacroiliac joints considerably varies in thickness.
