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.
