Fictional Dr. House character helps solve real-life medical mystery

Doctors were stumped by the symptoms exhibited by the 55-year-old man with severe heart failure. He had fever, swollen lymph nodes, hearing and vision loss when he arrived at the Center for Undiagnosed Diseases in Marburg, Germany. He also had a metal hip implant that replaced a previous ceramic one. The team of German doctors was no stranger to medical mysteries. They use a variety of resources to help pinpoint difficult-to-diagnose conditions. For this case, doctors recalled an episode of the then-recently-ended Fox TV series, House, a show in which the fictional character Dr. Gregory House solves some of the ... Read More

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

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

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

Researchers: More studies needed to determine long-term cancer risk with all-metal hip implants

Researchers are recommending long-term studies be done on patients with metal-on-metal hip replacement systems to determine whether corroding implants cause cancer. The recommendation was made following a study in which researchers found no increase in cancer in a seven-year period in people with all-metal hip implants. Traditional hip implants are made with plastic or ceramic parts, but in the past decade many manufacturers of these medical devices began making the devices with all metal parts. The metal hips were thought to be more durable and thus ideal for younger and more active patients. However, they devices were found to fail prematurely ... Read More

Cyclist files lawsuit against metal hip implant manufacturer

Mark Stephan was riding his bike with friends when he crashed and fractured two vertebrae. He was told he might never walk again. Yet, four years and a hip replacement later, Stephan defied the odds not only by walking again, but by completing a 3,200-mile cycling trip to raise money for the Rehabilitation Institute of Chicago, where he was treated. The victory was short-lived, however. Last year he received a letter stating that the Stryker Orthopedic hip replacement he received in 2011 was recalled because it was defective. Stryker warned that the faulty all-metal hip implants were at risk of ... Read More
