Smith & Nephew’s Oxinium oxidised zirconium technology receives regulatory approval in Japan

Smith & Nephew Orthopaedics : 04 March, 2008  (New Product)
Smith & Nephew’s Orthopaedic Reconstruction business has received Japanese regulatory approval for its award winning Oxinium oxidised zirconium technology.
Oxinium is a proprietary transformed metal alloy with a ceramic bearing surface. Oxinium provides low friction and wear resistance combined with the strength of a metal implant.

The material is the only orthopaedic Implant material to receive the ASM International Engineering Materials Award for outstanding achievement of a material used in the design and manufacture of products.

The approval marks the first time Smith& Nephew's technology will be available in the world's second largest orthopaedic market. The successful Genesis II knee system, which has been used in excess of 500,000 surgeries worldwide and has 10 year published clinical data showing 98 percent survivorship, will be the first Implant system available in Japan with Oxinium.

'This is an important milestone for Smith & Nephew and our Oxinium platform. Our premier technology is revolutionising joint replacement around the world by providing and maintaining unparalleled wear resistance,' said Joseph DeVivo, president of Smith & Nephew Orthopaedic Reconstruction. ' Oxinium material has proven to be a superior metal in implants, and our trail blazing technology has given patients the significant benefit of greater durability from their implants. We are pleased with the hard work our regulatory teams performed to make this innovative Implant material available for the numerous Japanese physicians and patients that have been anxiously awaiting this approval.'

Oxinium was developed and patented by individuals within Smith & Nephew Orthopaedic's Research, Development, and Manufacturing groups. All of Smith & Nephew's major knee and hip Implant systems, including the Genesis II Total Knee System, the Legion Total Knee System, the Journey BCS Knee system, the Journey DeuceKnee System, the Synergy Total Hip System and the Anthology Total Hip System, are available with Oxinium oxidised zirconium technology.

The first Oxinium oxidised zirconium component was implanted in 1995 and now more than 230,000 hip and knee components have been implanted with remarkable clinical success.
