Due Diligence and Deception

A post by Vivian Cheng at Science Progress chronicles a recent accusation of data-falsification in a study on a bone-growth treatment. Timothy Kuklo, a former Army orthopedic surgeon now at Washington University in St. Louis authored an article in the British Journal of Bone and Joint Surgery that said Medtronic's Infuse was better at treating severe leg injuries suffered by soldiers than traditional therapies. An investigation by the Army, reported on by the New York Times, concluded that Kuklo forged the signatures of four Army doctors -- none of whom saw the article prior to publication. The paper was retracted and Kuklo banned from future contributions. "The Walter Reed episode also shows how medical journals may fail to conduct adequate due diligence on the studies they publish — information that other doctors rely on for guidance," says the Times article by Barry Meier and Duff Wilson.
