Hip Resurfacing

What is hip resurfacing?

In a total hip replacement the worn ball at the top of the thighbone is removed. In hip resurfacing the ball is kept: it is reshaped and covered with a metal cap, and the socket is lined with a metal cup. More of your own bone is preserved.

Who may be a candidate

Hip resurfacing suits a small group of patients. It is generally considered for younger, active people with strong bone and a larger hip joint. It is generally not recommended for people with weak bone, some hip deformities, kidney problems or a known sensitivity to metal, or for women who may become pregnant. For most patients, a total hip replacement is the better operation.

How it compares with total hip replacement

• It preserves bone on the thighbone side, which can matter if another operation is needed years later.
• The larger ball can make the hip more stable.
• Because metal moves against metal, small amounts of metal are released into the body. Some patients react to it.
• The neck of the thighbone can fracture below the cap, which is a risk total hip replacement does not have.

Dr. Maish will tell you honestly which operation he would recommend if you were his family member.

Risks

In addition to fracture of the femoral neck and reactions to metal, every operation has risks. For joint replacement these include infection, blood clots, stiffness, continued pain, injury to nerves or blood vessels, fracture, and loosening or wear of the implant, any of which could require additional surgery. Dr. Maish spends an hour with you and your family before surgery going through the risks and what you can do to lower them.
