Bacterin International Holdings, Inc. (NYSE MKT: BONE), a leader in the development of revolutionary bone graft material and antimicrobial coatings for medical applications, announces that the first clinical results using the OsteoSponge ® product for foot and ankle arthrodesis have been published in The Journal ofFoot & Ankle Surgery. The article reports a multi-center, retrospective analysis of 80 joint fusions in 47 subjects who had undergone foot and ankle fusion procedures utilizing OsteoSponge bone graft. Overall, a fusion rate of 97.5% (78 of 80 joints) was determined by radiographic analysis. The article, titled “A Retrospective Analysis Evaluating Allogeneic Cancellous Bone Sponge for Foot and Ankle Arthrodesis,” reported comparable or greater foot and ankle fusion rates, as judged radiographically, to that reported in the biomedical literature. Additionally, at 12-month post-operative assessment, the authors observed statistically significant improvements in function and pain alleviation at rates greater than those previously reported in biomedical studies. “The data published in The Journal of Foot and Ankle Surgery serve as yet another testament to the efficacy of the OsteoSponge product,” said Guy Cook, Bacterin’s CEO. “We believe these results will aid in our goal of expanding Bacterin’s presence in the foot and ankle bone grafting market and are consistent with Bacterin’s mission of helping our surgeon users provide the best clinical outcomes for their patients.” About Bacterin International Holdings Bacterin International Holdings, Inc.
