Medpage Today/Milwaukee Journal Sentinel: Medtronic Helped Write And Edit Positive 'Infuse' Spine Studies
Highly positive studies published in peer-reviewed medical journals depicted Medtronic's spine fusion product as a major breakthrough in back surgery, but those studies (were) drafted and edited with direct input from company employees, while the doctors listed as authors were paid millions, according to a U.S. Senate investigation. The company's heavy, undisclosed manipulation of information about its bone morphogenetic protein-2 product called Infuse included removing and downplaying concerns about serious complications linked to the product and overstating its benefits. Over the course of 15 years, Medtronic paid $210 million to a group of 13 doctors who co-authored the series of now-repudiated papers about the product (Fauber, 10/25).
