2006 – Research shows dangers of metal-on-metal hip implants years before recall

Posted in DePuy Hip Replacement

Metal-on-metal hip replacements, particularly those manufactured by the Johnson & Johnson subsidiary DePuy Orthopaedics such as the ASR and ASRXL, have been associated with a high rate of device failure, requiring “revision surgery” – the surgical implantation of a new prosthetic hip joint.

In a 2006 paper titled “Loosening and Osteolysis Associated with Metal-on-Metal Bearings: A Local Effect of Metal Hypersensitivity?” published in The Journal of Bone and Joint Surgery, medical researchers Joshua J. Jacobs and Nadim J. Hallab describe another complication associated with the use of metal-on-metal hip implants: metallosis – metal poisoning resulting from high levels of tiny metal particles in the blood that shave off metal-on-metal hip implants with normal wear.

The authors discuss the differences in particles that wear off metal-on-metal implants as compared to those that wear off metal-on-plastic hips: “Even though the volumetric wear rate associated with metal-on-metal bearings is dramatically lower than that associated with metal-on-polyethylene bearings, the number of particles generated from metal-on-metal bearings is actually higher because the particles are an order of magnitude smaller.”

While it may seem to be better that the particles that come off metal-on-metal implants are small, it’s not.  The smaller the particles are, the more places in the body the particles can travel to, and the harder they are to remove.

Due to the fact that a number of people have used metal-on-metal hip implants, particularly the DePuy ASR/ASRXL models which were recalled in 2010, unaware of the risk for metallosis and other complications associated with these devices, a number of DePuy ASR hip replacement lawsuits and metal-on-metal hip replacement lawsuits have been filed.
