Published in 2009, medical researcher Joshua J. Jacobs wrote a report titled “Metal on Metal Bearing Surfaces”, that outlines some of the problems currently associated with hip implants. While metal-on-metal bearings is a popular option for repairing injured hip joints, it is the only option available for surface replacement of an injured joint. While many metal-on-metal (MOM) operations are successful, there are still many risks involved with the surgeries. The long term health effects of hip replacement surgery are not well-known and possible metal poisoning from the implants remain a serious concern for the health and safety of the users.
Older types of hip replacement implants used a metal-to-polyethylene bearings that allowed a greater amount to wear material to enter the bloodstream. While the newer metal-on-metal implants leak less particles into the bloodstream, metal particles can still wear off from the implants and the long term health effects of elevated levels of metal in the blood are not well studied. Signs of metal poisoning may include death of tissue surrounding the implant and can result in the formation of tumors. In many cases, metal-to-polyethylene bearings did not last as long as needed and forced some users to undergo replacement surgeries.
Joshua J. Jacobs states that “As more experience is gained with the so called second generation metal on metal bearings, intermediate term clinical results are now becoming available. Although these studies are generally favorable, there have been reports of osteolysis at short to intermediate term follow up”. Osteolysis is the weakening or breaking down of bone material and can lead to many health conditions. Inflammation from the implant and wear particles cause the trigger of the immune system that leads to osteolysis. This process makes bones brittle and allows the bones to easily fracture.
Due to the fact that many people have used metal-on-metal hip implants unaware of the risks associated with these devices, particularly the DePuy ASR/ASRXL hip replacement systems, a number of DePuy ASR hip replacement lawsuits are currently being filed. If you or a loved one used a DePuy ASR hip replacement system, and you suffered complications or device failure, you may be entitled to significant financial compensation from the manufacturer.
