Question #478

Considering the acetabulum, which of the follow statements is incorrect?

The acetabulum is formed from all three pelvic bones: the ilium, pubis and ischium. However, they do not finally fuse until after 20 years. Before this the three bones are separated by a Y-shaped cartilage, the triradiate cartilage. The three pelvic bones form their own primary site of ossification.

The acetabulum is lined by an incomplete ring of cartilage, the acetabular labrum. In addition, the acetabulum itself is also deficient inferiorly, the acetabular notch

In the anatomical position the acetabulum faces inferolaterally, while the obturator fossa is located inferomedially to the acetabulum.
