Hip Resurfacing System Eases Arthritis Pain

A new hip arthroplasty resurfacing system is intended for reduction or relief of pain and/or improved hip function in patients with non-inflammatory degenerative arthritis or inflammatory arthritis.

The Cormet Hip Resurfacing system is a metal-on-metal resurfacing artificial hip replacement system, surgically implanted to replace a hip joint. The system relieves hip pain and improves hip function by replacing parts of the hip joint that have been severely damaged by degenerative joint diseases such as osteoarthritis, rheumatoid arthritis, traumatic arthritis, dysplasia, or avascular necrosis. The system is intended for patients who, due to their relatively younger age or increased activity level, may not be suitable for traditional total hip replacement due to an increased possibility of future hip joint revision.

The system has two parts: an acetabular component--a socket in the shape of a shallow cup--and a femoral resurfacing component in the form of a ball head. During the procedure, the acetabular component replaces the damaged surface of the hip socket, while the femoral resurfacing component covers the femoral head. The components, made from highly polished metal, articulate within each other, forming a coupled bearing. The Cormet Hip Resurfacing system is manufactured by Corin (Cirencester, UK). The U.S. Food and Drug Administration (FDA) orthopedic and rehabilitation devices panel voted in favor of Corin's premarket approval application (PMA).

"We pioneered metal-on-metal resurfacing technology in the late 1980s, and our Cormet device has been sold and successfully implanted around the world for almost a decade,” said Ian Paling, Corin's CEO. "We are very confident that the opportunities for Cormet in the U.S. are substantial, as all our market research points to significant demand for this hip resurfacing technology, which is especially attractive to the younger, active ‘baby-boomer' generation.”
