Doctors considering whether to remove an implant similar to one now blamed for injuries in thousands of DePuy Pinnacle hip lawsuits should do so if the recipient has developed elevated metal ion levels, if the implant has undergone clinical or physiological changes, or if cups have loosened, said a presenter at the Current Concepts in Joint Replacement Winter Meeting.

Patients who have ion levels lower than 10, have a good X-ray and no clinical symptoms may not need to have their implants removed, the surgeon said during his presentation. “If you have an X-ray that has evidence of radiolucent lines around the entire cup, then you have a patient who you have to worry about — with or without symptoms.” According to a December 16th report from, he goes on to recommend that metal-on-metal hip recipients undergo testing every six months.

The doctor’s recommendations echo those made by Stryker Orthopaedics, who in July 2012 recalled its Rejuvenate and ABG II hip replacements for their potential to fret and corrode at the modular-neck junction. Patients began to suffer pain, swelling, and symptoms associated with metallosis (metal ion poisoning), which often require surgical removal of the device. Following the recall, Stryker recommended that all Rejuvenate and ABG II recipients obtain testing for metal ion levels, whether or not they are experiencing symptoms of early failure.

DePuy Pinnacle Lawsuits Allege Surgical Removal of Metal-on-Metal Hip

This has also been the case with many individuals who have pursued DePuy Pinnacle hip lawsuits involving a version of the device that includes a metal Ultamet liner. According to plaintiffs, whose cases have largely been centralized in a multidistrict litigation underway in the U.S. District Court, Northern District of Texas, the implant may raise a recipient’s metal ion levels in the bloodstream, resulting in the need for surgical removal.

A Case List updated on January 1, 2015 reflects continued progress in the federal DePuy Pinnacle litigation, with 7,161 claims now filed in the jurisdiction. Court records from a month earlier showed 30 fewer filings, which further allege that this particular devices shares design flaws with the company’s ASR implant. This hip replacement was recalled for unusually high failure rates.

The DePuy Pinnacle Hip Replacement System has not been available on the U.S. market since May 2013, when the company discontinued sales because of slowing market demand. At the time, the hip manufacturer insisted that safety concerns played no significant role in its decision to stop sales.
