Reba Golden hurt her back after falling two floors while building an addition to her house, but following a routine spinal surgery, she suffered blood clots, severe bleeding and died in 2007 on the operating table. She died after her doctor injected bone cement into her spine and some of the material leaked into her blood stream, causing clotting. She and other patients were never told Norian bone cement wasn’t approved by the Food and Drug Administration. Instead, Norian and parent company Synthes used surgeons in what one doctor called “human experimentation.” Federal prosecutors say the aim was to skirt a long, costly regulatory process.
