The head of the femur meets with the pelvis at the acetabulum, forming the hip joint . </P> <P> There are three bones of the os coxae (hip bone) that come together to form the acetabulum . Contributing a little more than two - fifths of the structure is the ischium, which provides lower and side boundaries to the acetabulum . The ilium forms the upper boundary, providing a little less than two - fifths of the structure of the acetabulum . The rest is formed by the pubis, near the midline . </P>
