Researchers find metal ion concentration, device brand may predict hip implant failure

The amount of metal ions in the blood and the type of hip implant may predict premature failure of metal-on-metal hip replacements, according to a team of United Kingdom researchers. Researchers reviewed data from 299 resurfacing procedures in 278 patients with various brands of hip implants. The patients had reported complications that were likely related to high levels of metal in their blood. Patients were put through a blood metal ion screening protocol, ultrasound scanning, and joint aspiration to determine the level of cobalt concentration. Researchers found that blood-cobalt concentration and the type of device used were significant risk factors ... Read More

Biomet to pay $56 million to settle metal-on-metal hip implant lawsuits

Medical device company Biomet Inc. has agreed to pay at least $56 million to settle multidistrict litigation (MDL) in Indiana federal court claiming its metal-on-metal hip replacement devices were defective. MDLs are special federal legal procedures designed to speed up the process of handling complex cases, such as product liability lawsuits. Biomet disputes the fact that its devices caused people harm, however it agreed to set aside the money for MDL plaintiffs who qualify. The agreement resolves the MDL, which it has been fighting since October 2012. Plaintiffs in the MDL who received either the Biomet M2a-38 or M2a-Magnum hip ... Read More

3 medical devices that can harm you

Medical devices are vitally important to the industry. They vary in complexity and application, from tongue depressors and disposable gloves to implants and prostheses. Because they are used to diagnose, prevent or treat disease or other conditions, these items are regulated by the Food and Drug Administration (FDA) to ensure their safety and efficacy. However, this does not guarantee the devices don’t have hidden design flaws that can cause serious health risks. Here are three commonly used medical devices that were designed to help people, but ultimately caused more harm that good: 1. Transvaginal mesh – Also known as vaginal ... Read More

Johnson and Johnson to pay $2.5 billion to resolve thousands of ASR metal hip lawsuits

Johnson & Johnson will pay more than $2.5 billion to resolve more than 7,500 lawsuits involving defective ASR metal-on-metal hip implants made by its subsidiary DePuy Othopaedics. DePuy issued a worldwide recall on an estimated 93,000 of its ASR all-metal hip replacement systems in 2010 after reports that the devices were failing at a faster than expected rate. Traditional hip implants can last 20 years or more before needing to be replaced. However, a large number of DePuy’s ASR devices were failing in five years or less. Unlike traditional hip implants that are made with ceramic or plastic parts, the ... Read More

UK’s National Health Service bans metal-on-metal hip implants

The United Kingdom National Health Service is banning surgeons from using metal-on-metal hip replacement systems in patients, based on guidance issued from consumer health watchdog the National Institute for Health and Care Excellence (NICE). The consumer health advocacy group developed the guidelines after investigations and research into the all-metal implants, which were found to have a startling high premature failure rate. Traditional hip implants are made with plastic or ceramic parts and generally last about 25 years before needing to be replaced. In the past decade, medical device manufacturers introduced all-metal artificial hips, assuming the devices would hold up better ... Read More

Stryker to pay up to $1.1 billion to resolve metal hip lawsuits

Medical device maker Stryker Corp. says it expects to pay up to $1.1 billion to settle personal injury lawsuits stemming from a 2012 recall of two of the company’s metal hip implants. The amount is more than twice what the company previously estimated it would have to pay to resolve the lawsuits. In July 2012, Stryker recalled its Rejuvenate and ABG II modular-neck stems because of concerns that the devices could fret or corrode inside the body, which could damage surrounding tissue and cause pain and inflammation. Last July the company in a securities filing said it estimated the costs ... Read More

DePuy settles ASR metal hip complaint before trial start

Johnson & Johnson has settled a personal-injury lawsuit that accused its DuPuy Orthopaedics unit of manufacturing defective metal-on-metal hip replacement devices. The lawsuit had been selected as a bellwether case among several other cases DePuy faces over its ASR hip implants, and was destined for an October 15 trial in San Francisco Superior Court. In March, a Los Angeles jury ordered DePuy to pay Loren “Bill” Kransky, a retired prison guard, $8.3 million in damages for injuries he allegedly received from an all-metal ASR hip device made by DePuy. Mr. Krannsky’s case was chosen as the first of more than ... Read More

Johnson and Johnson settles metal hip lawsuit

Robert Ottman was ready for his day in court against consumer health care products giant Johnson & Johnson. Ottman underwent total hip replacement surgery in 2008 during which he was implanted with Johnson & Johnson’s DePuy ASR metal-on-metal artificial hip system. Ottman claims the device caused him so much pain and disability that in 2011 he was forced to undergo invasive revision surgery to remove and replace the defective device. In 2010, Johnson & Johnson pulled the hip implants due to an alarmingly high number of premature failures. Ottman’s lawsuit claims that Johnson & Johnson and its subsidiary DePuy Orthopaedics ...

European Parliament considers stronger medical device oversight to better ensure patient safety

Europen Parliament is considering adopting a proposal that would give European drug and medical device regulators more control over medical devices, and require high-risk devices to undergo an approval process before they reach the market. In both Europe and the United States, most medical devices are cleared swiftly for marketing if they can prove they are similar to products already on the market. This has raised safety concerns in the past in both countries, especially after high-profile recalls and safety advisories including the worldwide recall of Johnson & Johnson’s DePuy Orthopaedic ASR metal-on-metal hip replacement system. The devices were granted ... Read More

Spanish king undergoes third hip replacement surgery due to joint infection

King Juan Carlos of Spain, 75, underwent a third hip replacement surgery less than two years after the last hip treatment, because the tissue surrounding the implant had become infected.  Carlos has undergone seven surgeries since 2010, including having both his hips replaced during three surgeries last year. The first hip replacement surgery came after he fell during an elephant-hunting holiday in Botswana. The monarch never gained full mobility after his last hip surgery and requires a cane to walk. It is not reported what type of artificial hip Carlos received. Traditional hip implants are made with ceramic or plastic ... Read More
