The testing of a bone-growth medical product on military veterans at Walter Reed Army Medical Center, perhaps without their consent, has raised questions from two U.S. senators. The New York Times reports that Hydrosorb Mesh, manufactured by Medtronics, was used in spinal fusion procedures in 35 patients at the medical center during an 18-month period.
