“Total Hip Joint Replacement  remains one of the most common and most successful Orthopedic approaches for people with hip problems,” says McLeod Orthopedic Surgeon Dr. Michael Sutton of McLeod Orthopaedics Dillon.  “Your surgeon replaces the injured or arthritic top of the leg (femur) with a stem and ball.  A cup is set into the hip to complete the cup-and-ball joint.”

Another lesser known, but occasionally discussed, repair for a bad hip is called resurfacing.  In this procedure, a cup section is still set into the hip.  However, rather than sawing off the top of the femur and replacing it with a metal stem and ball, the top of the leg bone is resurfaced and a cap is placed over it.

Hip Resurfacing Advantages

Surgeons who support resurfacing say that it is good for younger people with a bad hip, because a younger person may wear out the replaced or resurfaced joint.  And, proponents say, a resurfaced joint is easier to revise.

Another claim says there is less risk of a hip dislocation if it has only been resurfaced and not totally replaced. Supporters of replacement claim that dislocations are rare in either method.

Hip Resurfacing Disadvantages

There are a number of generally accepted drawbacks to resurfacing:

• There is a chance that the bone with the cap (femur) will crack.
• Bone density reduces over the years, making resurfacing less preferable for people over the age of 55.
• Resurfacing is a complex procedure that requires a long learning curve for the surgeon. With the smaller number of resurfacing’s that are appropriate, it is difficult for a surgeon to perform a sufficient number of resurfacing’s to become truly accomplished at it.

A European study of 434,650 hip operations between 2003 and 2011 produced definitive findings against resurfacing:

• Only 7.3% (or about 30,000) of the operations were hip resurfacing.
• The 5-year failure rate for hip resurfacing was 5%, compared to less than 2% for hip joint replacements.
• The failure rate in women was so high (nearly 5 times greater than men) that researchers recommended that resurfacing never be used for women.
• Researchers also noted that resurfacing should only be recommended to men with large hip bones.

Final Thought

Hip Resurfacing does have its advocates.  However, only a limited number of people are ideally suited for resurfacing.
