Hip Replacement

Osteoarthritis of the hip is the most common reason for a hip replacement. Osteoarthritis is caused by the wear and tear of aging. It causes the cartilage covering the joint surfaces to wear out, resulting in pain and stiffness.

Other conditions that can cause destruction of the hip joint include loss of the blood supply to the head of the thighbone (osteonecrosis), rheumatoid arthritis, injury, infection, and developmental abnormalities of the hip.

Traditional hip replacement surgery involves making a 10- to 12-inch incision on the side of the hip. The muscles are split or detached from the hip, allowing the hip to be dislocated.

Once the joint has been opened up and the joint surfaces exposed, the surgeon removes the ball at the top of the thighbone, or femur. The hip socket is prepared by removing any remaining cartilage and some of the surrounding bone. A cup-shaped implant is then pressed into the bone of the hip socket. It may be secured with screws. A smooth plastic bearing surface is then inserted into the implant so the joint can move freely.

Next, the femur is prepared. A metal stem is placed into the femur to a depth of about 6 inches. The stem implant is either fixed with bone cement or is implanted without cement. Cementless implants have a rough, porous surface. It allows bone to adhere to the implant to hold it in place. A metallic ball is then placed on the top of the stem. The ball-and-socket joint is recreated.

 

Doctor Biehl would be happy to discuss possible hip replacement surgery with you. He has had over 20 years of experience of joint replacement surgery.

You may benefit from hip replacement surgery if:
Hip pain limits your everyday activities such as walking or bending.
Hip pain continues while resting, either day or night.
Stiffness in a hip limits your ability to move or lift your leg.
You have little pain relief from anti-inflammatory drugs.
You have harmful or unpleasant side effects from your hip medications.
Other treatments such as physical therapy or the use of a gait aid such as a cane do not relieve hip pain.
