Newer hip implants may not be better than older models

When Dr. Art Sedrakyan and fellow researchers published the first paper on premature failures of metal-on-metal hip replacement systems in 2011, several medical device manufacturers responded by withdrawing their all-metal hip implants. It turned out the failures were caused when the metal parts rubbed against each other, causing metal bits to inflame neighboring tissue and leech into the bloodstream poisoning the blood. “Back in 2011 when we published the first paper on metal-on-metal hips, hundreds of people contacted me and asked if they should be worried about hip replacement in general,” says Sedrakyan, of the Patient Centered Comparative Effectiveness Program ...

Readers warn people with metal hip implants to have their blood checked for metal ions

“If you have a metal-on-metal (hip) replacement, it is imperative to have the metal ion test as soon as possible,” warned BJackson, in a comment on Missoulian’s Letters to the Editor. “My neighbor’s wife passed away a little over a year ago because of cobalt and chromium poisoning. .. she had the offending metal-on-metal (hip implant) removed and a new hip put in, (but) it was too late for her. They had spent three years telling her that she had ALS, but they were incorrect, and it was the metal-on-metal (hip implant) that killed her.” The comment was posted in ... Read More

FDA provides guidance to help medical device manufacturers gain faster marketing approval

The Food and Drug Administration (FDA) is providing manufacturers with information to help them win faster approval for medical devices deemed “substantially equivalent” to other devices, even if the technology of the new device is different or carries different risks. The guidance is designed to prevent defective medical devices from passing through the agency’s abbreviated 510(k) approval process, which allows faster clearance to moderate risk devices if they are similar to other devices currently on the market. The FDA has been revamping the 510(k) process since it was revealed four years ago that the faulty Johnson & Johnson DePuy ASR ... Read More

Johnson and Johnson to pay Oregon $4 million for deceptively marketing metal hip implants

Johnson & Johnson will pay $4 million to settle a lawsuit with the State of Oregon over claims that the company failed to warn doctors and patients that its artificial hip had a high failure rate. The settlement is being called the first of its kind by the Oregon Department of Justice. The settlement involves Johnson & Johnson’s subsidiary DePuy Orthopaedics’ ASR metal-on-metal hip replacement system, which was recalled in 2010 after mounting reports of premature failure. Not only were the devices failing at a higher than expected rate, in some cases the metal devices were corroding inside the body, ... Read More

Social media campaign takes aim at Johnson & Johnson

An activist group has launched a social media campaign attacking Johnson & Johnson, alleging the company’s transvaginal mesh implants have “hurt women across the country,” and is asking current and former employees to become whistleblowers and investors to divest or not to buy the company’s stock. The Corporate Action Network (CAN), a project of the Action Network Fund founded to address the imbalance of power between corporations and people, launched the campaign in an effort to gather more information against the company to strengthen a complaint the organization filed with the Department of Justice against Johnson & Johnson and its top ...

Increasing number of people in U.S. getting hip replacement surgery

An estimated 7 million people in the United States – or 2 out of every 100 – have had a total knee or hip replacement, according to a Mayo Clinic study. The research was the first major study to estimate how common joint replacement has become in the United States. Dr. Daniel J. Berry, chairman of orthopedic surgery at the Mayo Clinic and author of the study, reviewed federal databases on surgeries and life expectancy trends and reported those findings this month at the American Academy of Orthopaedic Surgeons conference in New Orleans. Until now, since the United States didn’t ... 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

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
