Younger women with metal hips more likely to require revision surgery

Metal-on-metal stemmed hip implants should no longer be used in patients, and patients with these artificial hips should be carefully monitored, particularly young women whose hip implants have large diameter heads, according to a new study. The study, conducted by researchers from the Universities of Bristol and Exeter, and the Centre for Hip Surgery at the Wrightingdon Hospital in Lancashire, was based on data from the National Joint Registry in England and Wales. Researchers looked at 402,051 first total hip replacements using a stemmed implant between April 2003 and September 2011. They then singled out revision operations carried out on ... Read More

Dozens of UK citizens sue DePuy, others for failed metal hips

Dozens of metal-on-metal hip replacement patients in South Yorkshire, Great Britain, are seeking damages from the manufacturers of the hip devices, alleging injuries ranging from device failure to toxic metal poisoning. According to The Star, 34 patients in South Yorkshire are suing DePuy Orthopaedics, maker of the ASR XL Acetabular and Hip Resurfacing systems, which the company recalled in August 2010 after medical data indicated a staggering number of the devices failed prematurely. Since then, patients have reported myriad problems, including intense pain, dislocation, immobility, bone fracture, muscle and tissue decay, nausea, and other severe complications linked to hip devices ...

Knee, hip replacement surgery puts older adults at risk for heart attack

People who are older than 60 who undergo knee or hip replacement surgery are at risk of having a heart attack in the weeks immediately following surgery, a new study shows. One in 200 older patients experience a heart attack in the six weeks following hip surgery, and 1 in 500 experience a heart attack in the six weeks following knee surgery. Elderly patients over the age of 80 are at greater risk. The study does not prove the surgeries cause heart attacks, but doctors speculate the stress of undergoing surgery and the disruption of the flow of blood and oxygen ... Read More

Plaintiffs allege DePuy hip implants caused extensive bodily damage

Plaintiffs from four states filed a lawsuit against Johnson & Johnson, its subsidiary DePuy Orthopaedics, and related companies in a Madison County, Wisconsin, Circuit Court June 29, seeking damages from injuries allegedly caused by metal hip implants made by DePuy. According to the complaint, 21 plaintiffs from California, Illinois, Indiana, and Missouri underwent hip replacement surgery, receiving DePuy metal-on-metal hip implants. However, the lawsuit alleges, instead of improving their lives, the devices malfunctioned and caused the plaintiffs to experience a spectrum of painful and crippling injuries, including bone and tissue loss, neurological injuries, cancer, liver and kidney damage, and other ...

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

Man undergoes six surgeries as result of defective metal hip

Eric Mets expected relief from pain after having hip replacement surgery in 2008, but his symptoms only got worse. It was puzzling not only to Eric, but to his doctors as well. Eric had been fitted with a newer hip implant, made with all metal parts and designed to be more durable. Traditional artificial hips are made with plastic or ceramic parts. Eric soon learned that his hip replacement had failed and he had to undergo revision surgery to remove and replace the implant. Revision surgeries for hip replacements are more invasive and require longer recovery than initial hip surgery. ... Read More
