Amedica’s four scientific presentations to highlight benefits of silicon nitride platform at ISTA

Four Scientific Presentations Demonstrate Superiority of Silicon Nitride over Existing Ceramics

Amedica Corporation (Nasdaq:AMDA), an innovative biomaterial company which develops and manufactures silicon nitride as a platform for biomedical applications, is pleased to announce all four submissions to the International Society for Technology in Arthroplasty (“ISTA”) were accepted for presentation during the 28^th annual congress occurring September 30 – October 3, 2015 in Vienna, Austria.

“Our presentations will demonstrate the rationale for using silicon nitride in total hip ceramic bearings,” said Dr. Sonny Bal, chairman and CEO of Amedica Corporation. “Our scientific data will convincingly demonstrate the serious limitations of other existing ceramics, while highlighting the advantages of silicon nitride, even as we begin testing of our femoral head product. I’m very proud of our continued innovation and robust science, which will be presented at this important scientific forum.”

Accepted submission titles and their authors include:

• Debunking the Myth That Ceramics Are Bioinert: Comparison of Alumina versus Silicon Nitride - B. Sonny Bal; Bryan McEntire; Mohamed Rahaman; Giuseppe Pezzotti
• The Effect of Accelerated Aging on the Material Properties of Ceramic Femoral Heads - Bryan McEntire; B. Sonny Bal; Mohamed Rahaman; Giuseppe Pezzotti
• Surface Modulation of Silicon Nitride Ceramics for Orthopaedic Applications - Ryan Bock; Bryan McEntire; B. Sonny Bal; Mohamed Rahaman; Marco Boffelli; Giuseppe Pezzotti
• The Effect of Ceramic Femoral Head Material Composition on Polyethylene Structure and Oxidation in Total Hip Bearings - Giuseppe Pezzotti; Leonardo Puppulin; Marco Boffelli; Bryan McEntire; Mohamed Rahaman; Kengo Yamamoto; B. Sonny Bal

ISTA is an annual congress focused exclusively on arthroplasty and attracts the field’s leading surgeons, researchers and device makers from around the world. Of the more than 700 abstracts submitted for presentation approval at the annual congress, ISTA and its reviewers selected all four of the Company’s submissions.
