BioMet hip replacements have been linked to metal poisoning among patients whose hip devices have failed or caused complications. The company’s BioMet M2a Magnum metal-on-metal hip replacement has demonstrated an increased risk of early fretting and corrosion, which can lead to metal poisoning.
Metallosis is a type of metal poisoning that occurs when detached metal debris and particles reach a toxic level in the bloodstream. The metal can result in severe tissue damage, limited mobility and the need for revision surgery.
An Australian study in 2011 found that patients with an M2a Magnum implants have a yearly revision rate of 7.2%, which is much higher than other devices. Patients have begun filing BioMet hip replacement lawsuits alleging that the manufacturers, BioMet Inc., released defective devices.
