At birth, each coxal bone starts out as three separate bones – the ilium, (ILL-ee-um), the ischium, (ISH-ee-um) and the pubis (PYOO-bus) bones – joined by hyaline cartilage. Figure 7.13 shows what these bones look like initially. By the age of 25, these three bones have fully fused into a single coxal bone.
