Coronal section through the lower portion
of L5 and the upper sacrum of a 77–year–old male with a history of
occasional mild low back pain and no radicular symptoms. The L5–SI
disc is completely resorbed and partially fused and a lem wide
zone of sclerosis borders the endplates on both sides. Especially on
the right side, sharp osteophytes at the margins of the disc project
laterally and force the L5 ganglion and nerve to curve around
these spondylotic ridges. The neural elements are bounded superiorly
by the base of the transverse process of L5 and inferiorly by the
ala of the sacrum. In the upper sacrum the wide (pelvine =anterior)
foramina are almost completely occupied by the voluminous SI
ganglia. The white horizontal line between the SI foramina
represents the vestige of the SI –S2 disc. |
