WebLecture Slide 08

The bony pelvis can be thought of as consisting of four separate elements: right innominate, left innominate, sacrum and coccyx. The innominate (or hip) bone is composed of three parts: ilium (blue), ischium (red), and pubis (yellow). Each of these develop from separate ossification centers. The three bones are connected by cartilage in the immature individual but ossify to form a single bone (the innominate) in the adult. All three bones contribute to the acetabulum, the large bowl shaped socket that articulates with the head of the femur at the hip joint.
