How the Hip Joint Works & Causes of Hip Pain

The hip is one of the largest joints in your body and works like a ball and socket. Part of the pelvis bone (acetabulum) creates the socket, and the top portion of your thighbone (femoral head) forms the ball. Articular cartilage covers the hip joint, and this slick tissue provides cushion for smooth movements when you walk or bend. That cartilage relies on lubrication for easy movement created by the synovial membrane tissue surrounding the ball and socket. Your hip joint is connected to ligaments that form a capsule for stability. When any of these hip joint parts are damaged by disease or injury, you can experience pain and limited mobility.

Arthritis is the primary cause of hip pain and disability. Hip dislocation, bone fracture or other injuries can cause osteonecrosis (avascular necrosis). Osteonecrosis happens when the blood supply to the “ball” portion of the joint is disrupted, damaging the bone’s surface and leading to arthritis. If you had hip problems as a baby or child, you might be more likely to have arthritis in the hip joint as you get older. There are several forms of arthritis, including osteoarthritis, rheumatoid arthritis and post-traumatic arthritis.

Total Hip Replacement Procedure Details

A total hip replacement removes and replaces the damaged cartilage and bone with prosthetic parts. A metal stem and metal or ceramic ball are used for the femoral head (the ball portion of the socket). The stem is fitted securely into the thighbone. The socket part of the hip joint (acetabulum) is replaced with a metal one that is cemented or held in place with “press-fit fixation” and sometimes screws. Damaged cartilage is also removed, and spacers made of metal, ceramic or durable plastic are placed between the artificial ball and socket to perform the same duties as the cartilage and synovial membrane. The result is a total prosthetic ball-and-socket joint that provides a smooth, pain-free motion so that you can enjoy long walks and up-and-down movements with ease.

Is Total Hip Replacement Surgery Right for You?

When medications, physical therapy and other treatment modalities fail to alleviate your hip pain and improve range of motion, hip replacement surgery may be your next step. Candidates for the procedure often have difficulty walking and bending and trouble resting due to hip stiffness and moderate to severe pain.
