TOTAL HIP REPLACEMENT

If your hip has been damaged by arthritis, a fracture, or other conditions, common activities such as walking or getting in and out of a chair may be painful and difficult. Your hip may be stiff, and it may be hard to put on your shoes and socks. You may even feel uncomfortable while resting.

If medication, changes in your everyday activities, and the use of walking supports do not adequately help your symptoms, you may consider hip replacement surgery. Hip replacement surgery is a safe and effective procedure that can relieve your pain, increase motion, and help you get back to enjoying your daily life.

First performed in 1960, hip replacement surgery is one of the most effective operations in all of medicine. Since 1960, improvements in joint replacement surgical techniques and technology have greatly increased the effectiveness of total hip replacements. According to the Agency for Healthcare Research and Quality, more than 300,000 total hip replacements are performed each year in the United States.

COMMON CAUSE OF HIP REPLACEMENT

The most common cause of chronic hip pain and disability is arthritis. Osteoarthritis, rheumatoid arthritis, and traumatic arthritis are the most common forms of this disease.

  • Osteoarthritis. This is an age-related “wear and tear” type of arthritis. It usually occurs in people 50 years of age and older and often in individuals with a family history of arthritis. The cartilage cushioning the bones of the hip wears away. The bones then rub against each other, causing hip pain and stiffness. Osteoarthritis may also be caused or accelerated by subtle irregularities in how the hip developed in childhood.
  • Rheumatoid arthritis. This is an autoimmune disease in which the synovial membrane becomes inflamed and thickened. This chronic inflammation can damage the cartilage, leading to pain and stiffness. Rheumatoid arthritis is the most common type of a group of disorders termed “inflammatory arthritis.”
  •  Post-traumatic arthritis. This can follow a serious hip injury or fracture. The cartilage may become damaged and lead to hip pain and stiffness over time.
  • Avascular necrosis. An injury to the hip, such as a dislocation or fracture, may limit the blood supply to the femoral head. This is called avascular necrosis (also commonly referred to as “osteonecrosis”). The lack of blood may cause the surface of the bone to collapse, and arthritis will result. Some diseases can also cause avascular necrosis.
  • Childhood hip disease. Some infants and children have hip problems. Even though the problems are successfully treated during childhood, they may still cause arthritis later on in life. This happens because the hip may not grow normally, and the joint surfaces are affected.

DESCRIPTION

In a total hip replacement (also called total hip arthroplasty), the damaged bone and cartilage are removed and replaced with prosthetic components.

  •   A metal or ceramic ball is placed on the upper part of the stem. This ball replaces the damaged femoral head that was removed.
  • The damaged cartilage surface of the socket (acetabulum) is removed and replaced with a metal socket. Screws or cement are sometimes used to hold the socket in place.
  • A plastic, ceramic, or metal spacer is inserted between the new ball and the socket to allow for a smooth gliding surface.

IS HIP REPLACEMENT SURGERY FOR YOU

The decision to have hip replacement surgery should be a collaborative one made by you, your general practitioner, and your orthopedic surgeon. The process of making this decision typically begins with a referral by your doctor to an orthopedic surgeon for an initial evaluation.

CANDIDATES FOR SURGERY

There are no absolute age or weight restrictions for total hip replacements.
Recommendations for surgery are based on a patient’s pain and disability, not age. Most patients who undergo total hip replacement are age 50 to 80, but orthopedic surgeons evaluate patients individually. Total hip replacements have been performed successfully at all ages, from young teenagers with juvenile arthritis to elderly patients with degenerative arthritis.

WHEN SURGERY IS RECOMMENDED

There are several reasons why your doctor may recommend hip replacement surgery. People who benefit from hip replacement surgery often have:

  • Hip pain that limits everyday activities, such as walking or bending
  • Hip pain that continues while resting, either during the day or night
  • Stiffness in a hip that limits the ability to move or lift the leg
  • Inadequate pain relief from anti-inflammatory drugs, physical therapy, or walking supports
