A woman who underwent procedures using Stryker’s bone growth putty and filler and Medtronic’s Infuse bone growth product sues the two companies for off-label promotion. A California woman is suing Medtronic Inc. (NYSE:MDT) and Stryker Corp. (NYSE:SYK), alleging that off-label marketing of spinal bone-growth products left her with debilitating injuries. April Cabana, 34, of Rancho Cucamonga, Calif., said she underwent back surgery for a herniated disc as a result of a car accident. She was treated using devices from both Stryker’s and Medtronic’s spinal fusion product lines, according to a complaint filed in the Superior Court for the state of California. According to Cabana, she was first implanted with Stryker bone putty and void filler, then underwent a second surgery using Medtronic’s Infuse bone graft and was ultimately left with debilitating pain.
