MEDICAL CONDITIONS OF THE HIP
AT GUSTAVEL ORTHOPEDICS
The hip is a ball and socket joint. The ball is the femoral head and the socket is part of the pelvis called the acetabulum. A thin smooth layer of cartilage (articular cartilage) covers both the femoral head and the acetabulum and allows low friction motions as the surfaces glide over each other. The acetabulum has a strong layer of cartilage (the labrum) that is on the outer margin of the bone forming a seal or gasket around the socket.
The strong ligaments and tissue that surround the joint and hold it together is the capsule. The inside of the capsule is lined by a thin layer of tissue called the synovium that produces fluid that lubricates the joint.
