On Nov. 16, 2011, Georgia Baddley, a 70-year-old woman living near Salt Lake City, received a shocking call from a special agent at the U.S. Department of Health and Human Services. The agent told her that the government had come across new information about her mother’s death. Baddley was speechless. Eight years before, her 83-year-old mother, Barbara Marcelino, had unexpectedly died during spine surgery. At the time, Baddley didn’t question what had happened; surgery was always risky for a woman of that age. She was horrified when the agent told her that the surgeon had injected bone cement into her mother’s spine and that the product -- which was not approved for that use -- may have played a role in her death.
