Skeleton Hip_Posterior View Stock Photography

The pelvic region of the trunk is the lower part of the trunk, between the abdomen and the thighs. Bony pelvis or pelvic skeleton is formed by hip bones, sacrum and coccyx. The pelvis is a ring structure made up of three bones: the sacrum and two innominate bones. The three bones and three joints composing the pelvic ring have no inherent stability without vital ligamentous structures. Bony pelvis is formed posteriorly by the sacrum and the coccyx and laterally and anteriorly by a pair of hip bones.
