In this video, I have described the anatomy of sacrum. Its features include base, pelvic surface, dorsal surface and two lateral surfaces. There are pelvic sacral foramina, dorsal sacral foramina, sacral canal and sacral hiatus. Thers are spinous tubecles forming median sacral crest, fusion of superior and inferior articular processes showing intermediate sacral crest and fusion of transverse processes showing lateral sacral crest. Only supperior articular process of first sacral vertebra is not fused showing sacral horns and inferior articular process of fifth sacral vertebra are not fused forming sacral cornu.
