<P> The hip bone is formed by three parts : ilium , ischium , and pubis . At birth , these three components are separated by hyaline cartilage . They join each other in a Y - shaped portion of cartilage in the acetabulum . By the end of puberty the three regions will have fused together , and by the age of 25 they will have ossified . The two hip bones join each other at the pubic symphysis . Together with the sacrum and coccyx , the hip bones form the pelvis . </P>
