Bones:

  • Joint Type:

  • Bones: Femur and Pelvis (1 - 4)

    • The pelvis is comprised of the pubis, ischium and ilium. These bones intersect in a "Y" shape at the acetabulum (1/5th pubis, 2/5th ischium, 2/5th ilium (3)), and although fused and ossified by early adulthood, they are actually separated by hyaline cartilage at birth.
