Understanding Hip Resurfacing

Hip resurfacing is a type of hip surgery to fix a damaged hip joint. The procedure is done by an orthopedic surgeon. This is a doctor with special training in treating bone, joint, and muscle problems.

About the hip joint

You have a hip joint on each side of your body. Each hip joint is made up of the rounded top of the thighbone (femoral head) sitting in a curved area (hip socket) in the pelvic bone. The joint is lined with a flexible cushion (cartilage). Normally the femoral head moves smoothly in the hip socket. When you have joint damage, the cartilage that normally lines the joint wears away. The bones no longer move smoothly. This causes pain.

Why hip resurfacing is done

You might need hip resurfacing if you have severe damage to your hip joint. Health conditions that may damage this joint include:

  • Osteoarthritis. This is also called wear-and-tear arthritis. The cartilage wears away from long-term use. This is the most common cause of damage.

  • Rheumatoid arthritis. This is a type of arthritis that affects not only joints, but the whole body. Without treatment serious joint damage may occur.

  • Osteonecrosis. This is damage caused by a decreased blood supply to a bone.

  • Injury. This may be a break (fracture).

  • Tumor. This is an abnormal growth of the bone. It may or may not be cancer.

Serious damage to your hip joint can cause pain and keep you from doing some of your daily activities. Hip resurfacing may help ease your pain, make it easier to move your hip, and improve your quality of life. Your doctor may advise hip resurfacing if other treatments don’t work. These can include pain medicine, special exercises, and a cane or walker.

How hip resurfacing is done

During hip resurfacing surgery, the surgeon smoothes the femoral head and the socket areas. The surgeon does not replace the femoral head. He or she puts a metal covering on the femoral head and on the socket. This surgery is different from total hip replacement surgery. In total hip replacement, the surgeon actually replaces the femoral head and puts a metal covering on the socket.

Risks of hip resurfacing

All surgeries have some risks. The risks of this surgery include:

  • Infection

  • Bleeding

  • Blood clots

  • Injury to nerves

  • Complications from anesthesia

  • Need for additional surgery

  • Break in part of the femur (femoral neck fracture)

Your risks vary based on your age and general health. For example, if you are a smoker or if you have low bone density, you may have a higher risk for certain problems. People with poorly controlled diabetes may also have a higher risk for problems. Ask your healthcare provider which risks apply most to you.
