Smith & Nephew recalls 7,700 metal hip devices

In June, medical technology corporation Smith & Nephew announced it is recalling its R3 Acetabular System, an optional metal liner component usually used in conjunction with stemmed total hip implants. This latest recall adds to growing fears over the high rate of premature failure associated with artificial hip implants made with metal-on-metal components and the speed at which many of these devices were rushed to market. “We regularly review the effectiveness of our products and are not satisfied with the clinical results of this component,” Andy Weymann MD, Smith & Nephew’s Chief Medical Officer said in a statement about the ...

New study sheds light on “genotoxic” damage rendered by metal hip implants

Researchers have a better understanding of why patients often suffer from inflammation and other long-term, chronic illnesses after being implanted with artificial hip devices made from all metal parts, such as the ASR hip implants recalled by DePuy Orthopaedics in August 2010. Researchers from Ohio State University and Imperial College London have combined high-resolution X-ray technology and electron microscopy to study the inflamed tissue surrounding the metal-on-metal hip devices implanted in patients. Their study, published in the journal Chemical Communications, found that inflammation occurs when Cobalt2+ ions are shed by the cobalt-chromium implants into the surrounding tissue. Previous studies have ... Read More

Canada issues new alert for metal hip patients and their doctors

Canadian regulators have issued a new alert for patients who have been implanted with metal-on-metal hip devices, advising them to watch for certain signs that could indicate the implants are failing. Prompted by growing concerns over the safety of hip implant devices made of all-metal components, Health Canada says that patients who have received such implants should “be on the lookout for pain the groin, hip or leg, swelling at or near the hip joint, or onset of a limp or change in walking ability or limited range of motion,” according to The Canadian Press. Much of the concern about ... Read More

UK regulators issue warning about DePuy’s MITCH TRH all-metal hip implants

The United Kingdom’s Medicines and Healthcare products Regulatory Agency (MHRA) has issued a safety warning for MITCH TRH acetabular cups and MITCH TRH modular heads – a metal-on-metal hip implant system manufactured by U.K.-based Finsbury Orthopaedics, a division of DePuy Orthopaedics. Both companies are owned by healthcare giant Johnson & Johnson. The MITCH TRH System is a metal-on-metal hip replacement system consisting of components that can be used in different combinations to carry out either hip resurfacing arthroplasty or total hip replacement. In the new Medical Device Alert, MHRA regulators warn that a higher-than-expected number of DePUY MITCH hip devices ... Read More

Some DePuy ASR hip implant lawsuits heading to trial this year

The first lawsuits filed against health care giant Johnson & Johnson and its subsidiary DePuy Orthopaedics by plaintiffs alleging injuries caused by DePuy’s metal-on-metal ASR hip devices will go to court this year. About 4,200 lawsuits have been filed against the companies in federal court, with another 2,000 filed in state courts. The first state lawsuits are slated to go to trial in Las Vegas, Nevada, in mid-December 2012, with another trial scheduled for January 2012 in a Maryland state court. Federal lawsuits, which will be tried in U.S. District Court in West Virginia, will probably be heard in March ... Read More
