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^: 1368² The floor of the fossa is formed mostly by the ischium;² it is rough¹^: 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 and by fibroelastic adipose tissue⁴¹^: 1368 (within which the acetabular branch of the obturator artery ramifies¹^: 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.⁴
