As Biomet M2a Magnum metal on metal hip replacement attorney, I have written extensively about the inherent early failure problems associated with metal on metal hips like the DePuy ASR, Pinnacle hip replacement models and others made by Biomet, Zimmer, Smith and Nephew and Wright.
In recent years, concerns have emerged about the safety of all metal-on-metal hip replacement systems. The metal-on-metal design causes cobalt and chromium metallic microscopic shards to shear off from the metallic articular surfaces through the grinding wear and tear mechanism. The articular surfaces involve the metallic surfaces of the acetabular cup, femoral head and taper sleeve.
There is mounting evidence of the significant risks that the patients are exposed to; including premature device failure, osteolysis (bone loss), bone and tissue damage, metallosis (metal poisoning) and heavy metal toxicity.
