Wright Medical Group, Inc. Announces Launch of PRO-DENSE(TM) Injectable Regenerative Graft

Breakthrough in Metaphyseal Bone Grafting Technology Now Available to Surgeons Worldwide

ARLINGTON, Tenn.--(HSMN NewsFeed)--Wright Medical Group, Inc. (NASDAQ: WMGI ), a global orthopaedic medical device company, today announced U.S. and international release of PRO-DENSE(TM) Injectable Regenerative Graft, a progressive new bone graft substitute that has demonstrated unique and highly favorable metaphyseal bone healing properties compared to autograft in preclinical studies.

A proprietary, patented composite of calcium phosphate and sulfate, PRO-DENSE(TM) Graft employs a unique, tri-phasic resorption profile providing the biologic environment to allow the body to quickly and reliably regenerate dense new bone. Extensive animal testing found that new bone regenerated by PRO-DENSE(TM) Graft was of greater density and greater compressive strength at 13 weeks than the new bone regenerated by autograft, which is widely considered to be the "Gold Standard" for bone grafting. Additionally, the testing revealed that the bone voids treated with PRO-DENSE(TM) Graft formed new bone at a faster rate than autograft.

"Our pre-clinical model suggests that the resultant bone repair properties could be a significant step ahead of currently available synthetics and DBM products," said Thomas Turner, D.V.M., Assistant Professor at Rush University Medical Center in Chicago and principle investigator for the pre-clinical model.

Receiving FDA clearance in February 2006, the PRO-DENSE(TM) Graft was released in a controlled fashion to select institutions to confirm human effectiveness over a 17-month period. "This has been a very controlled product release," stated John T. Treace, Vice President of Marketing for Wright's Biologics. "Extra time and resources were invested in order to generate strong clinical experience prior to our full-scale commercial release. Based on experience from 17 months of human use at top orthopaedic centers, we are confident that PRO-DENSE(TM) Graft will deliver our customers worldwide results yet to be seen with conventional bone grafts."

According to Joseph Borrelli, Jr., M.D., Chairman of Orthopaedic Surgery at UT Southwestern Medical Center in Dallas. "In my clinical practice, PRO-DENSE(TM) appears to be an excellent synthetic autograft substitute that may ultimately lead to better patient outcomes through its ability to lay down dense bone fast." Another clinical investigator, J. Tracy Watson, M.D., Chief, Division of Orthopaedic Traumatology at St. Louis University, explains, "I could tell by the early radiographic results that this material demonstrated a unique response, behaving differently than other alloplastic graft materials I have used previously for similar metaphyseal defects. The new bone regenerated was very impressive with active remodeling demonstrated throughout the healing period. We now have many patients treated with this material well out over a year, and this phenomenon has been consistent in all these cases."

PRO-DENSE(TM) Injectable Regenerative Graft is the latest addition to Wright's market-leading biologics franchise, which includes products such as GRAFTJACKET® regenerative tissue matrix, OSTEOSET® T Medicated Bone Graft (not available in U.S.), the ALLOMATRIX® line of demineralized bone matrix products, MIIG® X3 Injectable Graft, and the CANCELLO-PURE(TM) line of Sterile Xenograft Bone Wedges.
