The hip bone, innominate bone or coxal bone is a large, flattened, irregularly shaped bone. It has one of the few ball and socket synovial joints in the body – the so called hip joint. It meets its fellow on the opposite side in the middle line in front, and together they form the sides and anterior wall of the pelvic cavity.
Together with the sacrum and coccyx, it comprises the pelvis
From Wikipedia:

OS INNOMINATUM
The " os innominatum," so named by Galen, is made up of three bones, distinct in childhood, but united in the adult, and termed the "ilium," "ischium," and "pubes." Thus its constituents have received appropriate names, but the bone, consolidated, remains " nameless."

Ligament
(a) Suture
Joint held together with very short,interconnecting fibers, and bone edges
interlock. Found only in the skull.
(b) Syndesmosis
Joint held together by a ligament.Fibrous tissue can vary in length, but
is longer than in sutures.
(c) Gomphosis
“Peg in socket” fibrous joint.Periodontal ligament holds tooth
in socket.
