Acetabular Joint

The picture here is in Chinese that shows the acetabular bone.

I took a closer look at the report Dr. Tonks wrote about my surgery. One thing struck me was how the human pelvis functions. Acetabular joint looks insignificant on the X-ray, but its sophistication can only be appreciated in a 3-D model like this one. From Dr. Tonks' report, one of the worst part of my injury was the both-column acetabular fracture.
