Swelling and Permanent Damage From Metal on Metal Depuy Pinnacle Hip Implant

The DePuy Pinnacle hip lawsuits involving metal-on-metal hip systems continue to mount in the federal multidistrict litigation currently underway in the U.S. District Court for the Northern District of Texas. According to a Master Case List issued by the court on January 31, 2014, at least 5,590 DePuy Pinnacle lawsuits have been filed in the proceeding on behalf of individuals who were allegedly injured by a version of the Pinnacle Hip Replacement System that utilizes the Ultamet liner. (Orthopaedics Inc. Pinnacle Hip Implant Product Liability Litigation, MDL No. 2244)

All of the Pinnacle hip lawsuits pending in the Northern District of Texas allege that the all-metal design created by the Ultamet liner can cause the hip implant to shed dangerous amounts of microscopic metal debris into patients’ tissue and blood stream. Among other things, plaintiffs assert that the all-metal Pinnacle is flawed in much the same way as the DePuy ASR hip, which was recalled in 2010. This has caused much debate regarding whether or not the metal-on-metal Pinnacle hip system should be pulled from the market as well.


Many of the lawsuits allege that DePuy Pinnacle hip implants shed metal debris inside of the body and is released into the bloodstream, causing swelling, general pain, and metallosis (metal poisoning). Metallosis causes a number health complications including; general infection, thyroid problems, cognitive impairment, and cardiomyopathy, which can lead to heart failure.


According to an alert issued by the U.S. Food & Drug Administration (FDA) in January 2013, metal-on-metal hip implants may be more prone to premature failure than devices made from other materials, such as plastic or ceramic. Recipients of such implants who suffer pain, swelling, or other symptoms that might be indicative of failure should undergo metal ion blood testing to ensure their hip is functioning properly, according to the agency.


The FDA has also recommended stricter regulations for metal-on-metal hip implants, including a requirement that manufacturers of devices currently on the market conduct safety studies on their products if they plan to continue selling them. Consequently, this prompted a decision by DePuy Orthopedics to end sales of such devices, including the all-metal Pinnacle. Consequently, the Pinnacle litigation’s first bellwether trials are scheduled to begin in September 2014.
