PLAINSBORO, N.J., Mar 7, 2008 (PrimeNewswire via COMTEX News Network) -- Integra LifeSciences Holdings Corporation (Nasdaq:IART) announced today the introduction of Integra OS(TM) Osteoconductive Scaffold and the Trel-X(TM) and Trel-XC(TM) Demineralized Bone Matrix products through the Integra Extremity Reconstruction division. Each product has received clearance to be marketed in the United States from the United States Food and Drug Administration (FDA) and will be featured at the 75th annual American Academy of Orthopedic Surgeons (AAOS) Meeting this week.

This new family of osteobiologic products comprises three distinct product lines: Integra OS(TM) Osteoconductive Scaffold, a synthetic bone void filler manufactured from beta tri-calcium phosphate and type I bovine collagen; Trel-X(TM), a demineralized bone matrix; and Trel-XC(TM), a demineralized bone matrix premixed with cancellous bone.

Integra OS(TM) Osteoconductive Scaffold provides a three dimensional osteoconductive scaffold for new bone formation. The collagen portion of the matrix provides a binding site for the cells and proteins that are necessary for new bone deposition. When used in conjunction with patient derived bone marrow, Integra OS(TM) Osteoconductive Scaffold may substitute for harvesting bone graft material from the patient's iliac crest, thus sparing the patient additional surgery and postoperative pain.

Trel-X(TM) Demineralized Bone Matrix is provided in a reverse phase poloxamer carrier to provide exceptional handling characteristics and resistance to irrigation. Each lot of demineralized bone used to make Trel-X(TM) is tested for osteoinductive potential using an in vitro assay. The product is available as both a packable putty and injectable gel to address the varying requirements of reconstructive procedures.

Trel-XC(TM) Demineralized Bone Matrix combines the benefits of Trel-X(TM) with the addition of the osteoinductive properties of cancellous bone chips. Trel-XC(TM) is available as both a packable putty and an injectable paste. The paste form is one of the only available injectable demineralized bone matrix forms with premixed cancellous chips.

"We are very excited about launching our comprehensive line of synthetic bone graft substitutes and demineralized bone matrix products. The addition of these quality products leverages our presence in extremity reconstruction procedures and allows our sales organization to be a one stop shop for our customers," said Bob Paltridge, President of the Integra Extremity Reconstruction Division.

Bone graft substitutes are used in many of the more than 400,000 extremity fusion and osteotomy procedures annually. The extremity reconstruction bone graft market is estimated at more then $50MM annually in the United States.
