New York Times -- Two senators are raising new questions about an experimental use of a Medtronic device in spinal surgery on veterans and soldiers at the Walter Reed Army Medical Center from 2002 to 2004. Senators Max Baucus, Democrat of Montana and chairman of the Senate Finance Committee, and Charles E. Grassley of Iowa, the committee’s ranking Republican, wrote the commanding general of Walter Reed on Dec. 17 to ask about safeguards in a study by three Army surgeons.
