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 ...

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

Federal lawsuits, which will be tried in U.S. District Court in West Virginia, will probably be heard in March ... Read More

New study advises surgeons, patients avoid all-metal hip implants

A new study funded by the National Joint Registry of England and Wales and published this month in the British medical journal The Lancet calls on surgeons to stop using metal-on-metal hip implants completely, saying that evidence shows patients who receive the implants are much more likely to need revision surgery to have the implants repaired or replaced. The study’s authors analyzed data from the National Joint Registry of more than 400,000 hip replacements made from 2003 to 2011. While the vast majority of those surgeries involved traditional implants made of plastic or ceramic, more than 31,000 patients received metal-on-metal ... Read More

New Zealanders who say they were injured by DePuy hip implants find hope in UK litigation

A group of New Zealanders allegedly harmed by metal-on-metal hip implants manufactured by DePuy Orthopaedics is joining an international lawsuit against the company. According to Farifax NZ News, about 30 New Zealanders learned they were eligible to sue DePuy under English law and are currently working with a barrister (lawyer) in the U.K. to file their claims in the British court. Their eligibility comes as good news to all 507 New Zealanders who have been implanted with one of DePuy’s recalled ASR (articular surface replacement) hip devices, which have been implanted in about 93,000 patients worldwide. The plaintiffs are not ... Read More

DePuy hip implant leads to renewed pain, hardship for Minnesota woman

Terri, a mother of twin college-age daughters and a grown son, told the Minnesota StarTribune that the DePuy ASR artificial hip she received in 2008 to counter the chronic arthritis in her right hip gave her a new lease on life. As she recovered from replacement surgery, the pain subsided and her mobility improved dramatically. The increased activity allowed Terri to shed excess weight, and she went from 219 pounds to 165 in just a year. But in late 2009, her right hip popped, the pain came back, and all her progress stopped. In fact, she found herself sliding backward ... Read More
