The Sacrum is a triangular bone formed by the union, and ossification of the five vestigial vertebrae, classified as S1-S5. The sacrum is located in the posterior portion of the pelvic cavity between the two hip bones (also called Ilium--together making up the sacroiliac joints). The female sacrum is shorter,wider, and more curved between th S2 and S3 segments than the male
sacrum, due in part to the birth canal, and a slightly different center of gravity. The sacrum fuses around the age of five years old. The triangular shape is responsible for distributing the weight of the upper body onto each leg. When walking, the surfaces of the sacrum and the ilium move in a "circle eight" pattern known as nutation, that helps the human body to walk more smoothly, decreasing wear and tear throughout the entire spinal column.
hope this information will help you.

The sacroiliac joint or SI joint is the joint in the bony pelvis between the sacrum and the ilium of the pelvis, which are joined together by strong ligaments. In humans, the sacrum supports the spine and is supported in turn by an ilium on each side. The joint is a strong, weight bearing synovial joint with irregular elevations and depressions that produce interlocking of the two bones. The human body has two sacroiliac joints, one on the left and one on the right.
