The three bones are initially separated by a y shaped triradiate cartilage that begins to fuse after puberty.

The acetabulum æ s ə ˈ t æ b j ʊ l ə m cotyloid cavity is a concave surface of a pelvis. It creates a smooth low friction surface that helps the bones glide easily across each other during movement. Ligaments of the hip joint.

The upper leg is called the femur bone and at the very top of that bone there is a ball like structure called the femoral head the closed fist so in short the acetabulum is the cup shaped portion of the hip bone that receives the femoral head of the femur bone and together these two bony structures form the hip joint. The acetabulum is ringed by strong fibrocartilage called the labrum. Bursae in the hip.

All three bones of the pelvis the ilium ischium and pubis together form the acetabulum. Ligaments of the hip are extremely tough and strong. The hip joint or acetabulum is responsible for many movements including walking.

Gross anatomy the acetabular labrum is a c shaped fibrocartilaginous structure with an opening anteroinferiorly at the site of the acetabular notch. The acetabulum is the socket of the ball and socket hip joint. Elsewhere it is attached to the margins of the acetabulum.

Although simplicity is suggested in its most basic understanding as a containing device for the femoral head the acetabulum in reality is a complex and elegantly designed structure. The head of the femur meets with the pelvis at the acetabulum forming the hip joint. Hip anatomy the acetabular joint the hip joint.

Anatomy of the acetabulum. Pectoral girdle and pelvic girdle contributes a part of the acetabulum the deep cavity into which the head of the thighbone or femur is fitted.
