Acetabulum of pelvis9/8/2023 Ischiofemoral ligament: This is a group of strong fibers that arise from the ischium behind the acetabulum and merge with the fibers of the joint capsule.It attaches the pubis to the femoral head. Pubofemoral ligament: This is a triangular shaped ligament that extends between the upper portion of the pubis and the iliofemoral ligament.It helps in limiting over-extension of the hip. Iliofemoral ligament: This is a Y-shaped ligament that connects the pelvis to the femoral head at the front of the joint.The ligaments adjoining the hip joint include: The hip joint is encircled with ligaments to provide stability to the hip by forming a dense and fibrous structure around the joint capsule. Ligaments are fibrous structures that connect bones to other bones. It enables smooth movements of the bones and reduces friction. Next to the femoral neck, there are two protrusions known as greater and lesser trochanters which serve as sites of muscle attachment.Īrticular cartilage is the thin, tough, flexible and slippery surface lubricated by synovial fluid that covers the weight-bearing bones of the body. The head of the femur joins the pelvis (acetabulum) to form the hip joint. The upper part of the thighbone consists of the femoral head, femoral neck, and greater and lesser trochanters. The femur is one of the longest bones in the human body. A fibrocartilaginous lining called the labrum is attached to the acetabulum and further increases the depth of the socket. The head of the femur rotates and glides within the acetabulum. The stability of the hip is provided by the joint capsule or acetabulum and the muscles and ligaments that surround and support the hip joint. The lower part of the ilium is attached by the pubis while the ischium is considerably behind the pubis. The acetabulum is a deep, circular socket formed on the outer edge of the pelvis by the union of three bones: ilium, ischium and pubis. The ball of the hip joint is made by the femoral head while the socket is formed by the acetabulum. It is comprised of two bones: the thighbone or femur, and the pelvis, which is made up of three bones called ilium, ischium and pubis. The hip joint is the junction where the hip joins the leg to the trunk of the body. Nerves and blood vessels that supply the bones and muscles of the hip.The hip joint is made up of the following: The thighbone or femur and the pelvis join to form the hip joint.Īny injury or disease of the hip will adversely affect the joint's range of motion and ability to bear weight. It is also referred to as a ball and socket joint and is surrounded by muscles, ligaments and tendons. The hip joint is the largest weight-bearing joint in the human body.
