Pelvis anatomy in 3D
The bony pelvis, formed by the two hip bones, the sacrum and the coccyx.
Each hip bone is formed by the fusion of the ilium, ischium and pubis, which meet at the acetabulum, the socket of the hip joint. The pelvic inlet separates the greater pelvis above from the lesser pelvis below, and its shape differs between males and females.
