The acetabulum is a concave surface formed by the three bones of the hip bone: the pubis, ilium and ischium. It is located on the lateral aspect of the hip bone. It contains a non-articular area and an articular area, which articulates with the head of the femur. This articular surface is called the lunate surface. The lunate surface is crescent-shaped and is widest anterosuperiorly. The lunate surface is covered by articular cartilage, which is thickest in the broadest region. It is also lubricated with synovial fluid to reduce friction. The non-articular area is referred to as the acetabular fossa.
Latin synonyms: facies lunata acetabuli
