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]: 1368 [2] The floor of the fossa is formed mostly by the ischium; [2] it is rough [1]: 1354 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]: 1368 It is occupied by the ligament of head of femur, [3][ better source needed] and by fibroelastic adipose tissue [4] [1]: 1368 (within which the acetabular branch of the obturator artery ramifies [1]: 1250 ) that is mostly lined with synovial membrane. [1]: 1368 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.
