Sacrum posterior

Posterior view of the sacrum as a triangular fused bone at the base of the vertebral column, off-white to pale ivory, broad superiorly and tapering inferiorly. The dorsal surface is more convex and rougher than the pelvic surface, showing fused ridges including a prominent median sacral crest along the midline, with paired posterior sacral foramina on either side.
