As a DePuy ASR Recall and DePuy Pinnacle Replacement attorney, I have written extensively about the inherent early failure problems associated with metal on metal hips like the DePuy ASR and Pinnacle hip replacement models. Now other metal on metal hip manufacturers are under fire for allegedly making and selling defective hips. These include metal on metal hip devices made by Biomet, Zimmer, Smith and Nephew and Wright.
Metal-on-metal implants gained popularity because they were thought to be more durable and provide a better long term solution for individuals with more active lifestyles. In many cases just the opposite has been true, with a significant number of patients experiencing failure of the implant in only a few short years and requiring revision surgery to replace the device.
Recently Stryker Orthopedics announce a recall of their Rejuvenate Modular Hip and ABG II models. Read details here. Recent medical studies have indicated that other metal-on-metal hip replacement systems, including the Biomet M2A Magnum, Zimmer Durom, Wright Conserve, and DePuy Pinnacle have increased failure rates when compared to systems made from alternative materials such as ceramic or polyethylene.
