(BRYN MAWR, PA; February 23, 2008) -- Eric Smith, MD , Orthopedic Surgeon at Bryn Mawr Hospital, is among an elite group of surgeons nationwide trained in the new Cormet™ Hip Resurfacing technique, a breakthrough alternative to total hip replacement that preserves more of a patient's natural bone structure and stability and has the potential to return patients to more active lifestyles.

"Hip resurfacing is a viable alternative to more traditional hip replacement methods for many people, particularly younger, more active patients who suffer from hip arthritis and other degenerative joint diseases," said Dr. Smith. He noted that hip resurfacing is not for everyone; it is more appropriate for young, active patients with good bone quality.

The primary advantage of resurfacing, explains Dr. Smith, is bone preservation. The hip joint is made up of the rounded head ("ball") on top of the thigh bone (femur) that fits into a deep cavity,  the acetabulum ("socket").  In hip replacement, the ball and the top of the femur are removed and replaced with an implant.  During hip resurfacing the ball is simply shaved, reshaped, and covered with a metal cap instead of being removed, much like the capping of a tooth.  The socket is replaced in both procedures.

This approach may reduce the post-operative risks of dislocation and inaccurate leg length, often associated with total hip replacement, and because the all-metal implant is made from tough, smooth cobalt chromium, it has the potential to last longer than traditional hip implants.

"Some studies have shown that the resurfacing implant is more stable than a total hip replacement, so patients can enjoy more strenuous physical activity after the healing period, which is a huge benefit for young active people," said Dr. Smith.

According to Dr. Smith, much is still unknown about the long-term safety and durability of the resurfacing devices compared with the total hips and that most patients, particularly those older than 65, may be better off with the traditional technology.
