The pelvic girdle (or bony pelvis) comprises of: Two hip bones (or innominate bones: triangular blades twisted 90 to each other, formed from 3 bones: ilium, ischium and pubis (which fuse at acetabulum) Sacrum: consists of 5 fused vertebrae, triangular in shape. Coccyx: remnant of the tail, consists of 4 fused coccygeal vertebrae. Supports body weight transmitted through the vertebrae, thence through the sacrum across the sacroiliac joints to the innominate and then to the femora in the standing position, or to the is(cid:272)hial tu(cid:271)erosit(cid:455)(cid:859)s (cid:449)he(cid:374) sitti(cid:374)g. During walking, the pelvis swings from side to side by a rotary movement at the hip joint which occurs together with small movements at the lumbar vertebral joint. 1. 2 on the sacrum, identify: auricular surface, lateral sacral crest, sacral foramina.
