The sacrum is an irregular sphenoid bone that makes up the back posterior third of the pelvic girdle.
The sacrum is made up of 5 fused vertebrae S1-S5 and 3 to 5 small bones fuse creating the coccyx. The sacrum is a very strong bone that supports the weight of the upper body as it is spread across the pelvis and into the legs. The name sacrum designating the more or less flat bone with eight holes located at the base of the spine comes directly from Latin os sacrum meaning sacred bone. The female sacrum is shorter and more extensive than a males.
