Axial section through the upper sacrum lcm
caudal of the level in Slide 19. The sacroiliac joints are partially
devoid of cartilage. Between the wide ventral (pelvine) sacral
foramina the vestige of the S1–S2 disc is seen. A complex array of
coarse fibers connects the sacrum to the sacrum to the iliac bone
behind the sacroiliac joint. On the right side an elevation of the
lateral crest of the scrum articulates with the tip of the ilium
through a neoarthrosis. Note the virtual absence of cancellous bone
in the lateral portions of the sacrum; the bone is replaced by bone
marrow that has undergone fatty degeneration. The texture of the
cancellous bone is preserved in the body–portion of SI, in its
lamina and spinous process.
Color figures 3–9A, 3–9B and 3–10 depict a severe degenerative
spinal stenosis at L4–L5 in a 70 year–old man with intermittent
claudication and an isthmic spondylolisthesis at L4–L5 in a 44
year–old man with a history of recurrent radicular pain. These three
illustrations are identical with Slides #7, #8 and #10 in the Slide
Set "Thoracolumbar Spine Anatomy and Pathology". |
