Answer:
The left and right hip bones (innominate bones, pelvic bones) are two irregularly shaped bones that form part of the pelvic girdle – the bony structure that attaches the axial skeleton to the lower limbs.
The hip bones have three main articulations:
Sacroiliac joint – articulation with the sacrum.
Pubic symphysis – articulation between the left and right hip bones.
Hip joint – articulation with the head of femur.
In this article, we shall look at the anatomy of the hip bones – their composition, bony landmarks, and clinical relevance.

Composition of the Hip Bone
The hip bone is comprised of the three parts; the ilium, pubis and ischium. Prior to puberty, the triradiate cartilage separates these parts – and fusion only begins at the age of 15-17.
Together, the ilium, pubis and ischium form a cup-shaped socket known as the acetabulum (literal meaning in Latin is ‘vinegar cup‘). The head of the femur articulates with the acetabulum to form the hip joint.
