BOSTON--(BUSINESS WIRE)--Orthofix International N.V. (NASDAQ: OFIX) today announced that a federal False Claims Act, or qui tam, complaint filed against the Company and its Blackstone Medical, Inc. subsidiary on September 29, 2006 was unsealed late Friday by the United States District Court for the District of Massachusetts. Importantly, the Company believes that the allegations contained in the complaint pre-date the acquisition of Blackstone, completed on September 25, 2006. The unsealing of the qui tam action is routine procedure and allows the two individual plaintiffs involved to pursue the case in the normal civil litigation system. The Department of Justice (DOJ) has declined to intervene in the matter at this time.
