As the nation’s first DePuy ASR trial progresses into its second week in Los Angeles, a metal-on-metal hip implant expert testified Feb. 6 that the device’s design had several alleged flaws, notes the Rottenstein Law Group, which represents clients in DePuy ASR lawsuits.
According to a Bloomberg article,* Dennis Bobyn, a McGill University professor, testified in court (In re: Loren Kransky and Sheryl Kransky v. DePuy, Inc., et al. BC456086, Los Angeles Superior Court) that the recalled ASR’s shape and function – a less-than-half-circle metal cup in which a metal ball sits – contributed to the alleged flaws, as does its one-piece cup design. (Two-pieces is considered a better approach, Bobyn said.)
The alleged design flaws can cause metallosis (metal poisoning), which is one of the most prominent conditions for which hip implant recipients pursue lawsuits with firms such as the Rottenstein Law Group. Contact between hip components results in metal ions that enter the bloodstream. Alleged side effects include the blackening of and growth of “pseudotumors” in the surrounding tissue and adverse effects in the central nervous system.
