Metal-on-metal hip implants have led to some patients developing metallosis, a condition in which build-up of metal debris in the soft tissues of the body occur.
While all surgeries carry some risk, the type of implant used in hip replacement procedures may carry additional risks. For example, studies show metal-on-metal implants have greater risk of loosening or early failure because metal particles released from the device may weaken nearby bone and tissue. Popular brands of metal-on-metal implants include the DePuy ASR and Pinnacle, Smith & Nephew Emperion and Birmingham Hip and the Biomet M2a-Magnum.
Recently a growing number of lawsuits have been filed against the makers of metal-on-metal hip implants after patients developed metallosis.
