Which term describes the boundary of the acetabulum on its superior aspect?

• A. Acetabular Floor
• B. Pelvic Inlet
• C. Pubic Symphysis
• D. Acetabular Roof

Answer: (D)

In the acetabulum, the top edge forms what is called the acetabular roof. This superior boundary caps the socket and is distinct from the acetabular floor, which is the lower part of the socket that bears weight. The pelvic inlet is a larger pelvic boundary, and the pubic symphysis is the front joint of the pelvis, not the boundary at the top of the acetabulum. So the term for the boundary on the superior aspect is the acetabular roof.
