The hip is a ball and socket joint and is capable of movements in all directions.
The femur (thighbone) has a ball-shaped head which is covered with a protective cushion of articular cartilage. The head of the femur fits snugly into a round socket in the pelvis called the acetabulum which is also lined with cartilage. A further cartilage lip, known as a labrum, extends around the socket providing strong stability to the natural hip joint.
The ball and socket are both enclosed by a joint capsule which has a smooth lining called the synovium. This membrane releases a fluid that lubricates the cartilage and reduces friction.
A large number of muscles, tendons and ligaments run across the joint to assist with normal movement and stability. In addition, a number of major nerves, including the sciatic and femoral nerves, supply the muscles acting on the hip joint as well as the joint itself.
