As a DePuy ASR Recall and DePuy Pinnacle Replacement attorney, I have written extensively about the inherent problems associated with metal on metal hips like the DePuy ASR, Pinnacle hip relacement models and others made by Biomet, Zimmer, Smith and Nephew and Wright.
According to the FDA health experts there is no compelling reason to continue using metal-on-metal hip implants. There is overwhelming and mounting evidence that these metal on metal devices can break down early and expose patients to dangerous metallic particles, a condition known as metallosis.
