acetabulum
Yes, it is concavity on lateral side of coxal bone for articulation with femur.
The coxal bone parts include the ilium, ischium and pubis
ball and socket
acetabulumThe ilium, ischium, and pubis fuse at the deep hemispherical socket called the acetabulum (literally, "wine cup"), which receives the head of the thigh bone.
The fully developed, adult coxal bone (or innominate bone or hip bone) is made up of three parts: The ischium, the ilium and the pubis. These three bones meet at the triradiate cartilage in an immature individual and eventually fuse as the individual reaches skeletal maturity (15-16 years old). The triradiate cartilage can be found at the base of the acetabulum.
