Medically reviewed by Min Clinic Staff | Updated: January 2026
Joint, acetabular: The hip joint. The acetabulum is the cup-shaped socket of the hip joint, and it is a key feature of the pelvic anatomy. The upper end of the femur (thighbone) fits right into the acetabulum, articulates with it, and thereby forms the largest ball-and-socket joint in the human body.
