More than 1,800 DePuy Pinnacle Hip implant lawsuits are now part of the multidistrict litigation centralized under Judge James E. Kinkeade in U.S. District Court for the Northern District of Texas, and the number continues to grow.
The DePuy Pinnacle hip implant system is the predecessor to the DePuy ASR hip system. 93,000 of the ASR metal-on-metal device were recalled in 2010. The Pinnacle system, also a metal-on-metal device has not been recalled, and news sources estimate that more than 150,000 patients have been implanted with the device. About 37,000 patients in the United States were implanted with the ASR device, and as such, experts believe the Pinnacle lawsuits will far outnumber those filed against the ASR. Dr. Mary O’Connor, a Mayo Clinic Orthopedic surgeon believes that “We’re simply seeing the tip of the iceberg with metal-on-metal failures,” DrugWatch reports.
Many of the Pinnacle lawsuit allege earlier than normal failure rates, which force patients to undergo risky revision surgery to remove and/or replace the defective device. Another serious issue with all metal-on-metal hip implants is the shedding of metal debris into the body, called metal poisoning or metallosis. Experts say that when the metal ball and socket components rub together, metal ions are released causing damage to surrounding tissues. At least one study has linked this metal shedding to bladder and kidney cancer.
