The U.S. Southern District Court of New York threw out a lawsuit against Zimmer Biomet related to its Taper hip implant and Kinectiv piece.
Five things to know:
1. Tamma Nutting, from Idaho, had total hip replacements performed by Mark Meier, MD, March 15, 2011, and June 18, 2012, with Zimmer Biomet's Taper and Kinectiv piece, according to court documents filed Aug. 6. She had a revision surgery on her right hip Dec. 14, 2017.
2. Ms. Nutting alleged that the devices were prone to micromotion between the components and led to metal release and corrosion. She alleged that this caused tissue necrosis and pain that led to revision surgeries to replace the products.
3. The court found Ms. Nutting didn't produce "evidence sufficient for a reasonable jury to find that any alleged failure to warn was the proximate cause of [her] injuries." It also found that Ms. Nutting didn't "establish a genuine issue regarding the existence of a defect or that a failure to warn proximately caused her injuries."
4. The court also excluded testimony from a biomedical engineer because it was found to be "unreliable and unhelpful."
5. The court granted Zimmer Biomet's request to exclude the engineer's testimony and a summary judgement on Ms. Nutting's allegations.
