1.ARTICULAR SURFACE OF HIP JOINT:
The Hip Joint Is A Ball And Socket Synovial Joint, Formed By An Articulation Between The Pelvic Acetabulum And The Head Of The Femur. It forms a connection from the lower limb to the pelvic girdle, and thus is designed for stability and weight-bearing – rather than a large range of movement.
The acetabulum is a cup-like depression located on the inferolateral aspect of the pelvis. Its cavity is deepened by the presence of a fibrocartilaginous collar – the acetabular labrum. The head of femur is hemispherical, and fits completely into the concavity of the acetabulum.
