The acetabular fossa is the non-articular depressed region at the centre of the floor of the acetabulum. It is surrounded by the articular lunate surface.[1]Template:Rp[2] The floor of the fossa is formed mostly by the ischium;[2] it is rough[1]Template:Rp and thin (often to the point of transparency). The space of the fossa is continuous inferiorly with the acetabular notch.[2]
The fossa does not contain any cartilage.[1]Template:Rp It is occupied by the ligament of head of femur,[3]Template:Better source needed and by fibroelastic adipose tissue[4][1]Template:Rp (within which the acetabular branch of the obturator artery ramifies[1]Template:Rp) that is mostly lined with synovial membrane.[1]Template:Rp The acetabular "fat pad" is thought to contain abundant proprioceptive nerve endings that sense compression of the fat pad or its displacement through the acetabular notch, producing proprioceptive information.[4]
