FDA: Metal-on-Metal Hip Implant Patients Risk Soft Tissue Damage

Metal-on-metal hip implants have been in the spotlight lately for the lawsuits associated with patients claiming to be injured by their faulty design. The litigation prompted the U.S. Food and Drug Administration (FDA)  to call for manufacturers of these devices to conduct studies examining safety and efficacy, and has added warnings of its own the the medical devices. Companies such as Johnson & Johnson and its subsidiary DePuy Orthopeadics; Smith & Nephew; and Wright Medical manufacture metal-on-metal hip implant designs that have been shown to fail at an alarmingly high rate. In an article published by Medical News Today, the FDA states that there aren’t ... Read More

Metal-on-Metal Hip Implants Causing Metal Poisoning and Metallosis

Metal-on-metal hip implants such as the DePuy ASR that uses a metal ball and cup or designs such as the Stryker Rejuvenate and ABG II  that uses a metal neck and stem have caused many patients to have adverse effects because of the corrosion of the metal components within the body, resulting in thousands of lawsuits. All of these components are made of cobalt and chromium which, upon corrosion and wear-down, can flake metal particles into the body and cause metallosis. The body naturally stores a certain level of chromium and cobalt, which promotes healthy cellular function. However, when these metal components from a hip ... Read More

Biological hip joint replacement may be better option for younger patients than traditional hip replacement

Researchers at the University of Missouri School of Medicine have been busy testing a new technique for biological hip joint replacement surgery. This technique is designed to give younger, more active patients better and longer-lasting joint function, and is intended to reduce the pain caused by traditional total hip replacements. Total hip replacements involve using an artificial hip with plastic or metal components that begin to wear right away. These traditional repairs have a limited life expectancy and usually require restricted activity. In the past 20 years, manufacturers such as Johnson & Johnson and DePuy Orthopedics, among others, have designed some ... Read More

Metal hip manufacturer faces new lawsuits alleging defective design

At least five new lawsuits were filed against Stryker Corp., and its subsidiary Howmedica Osteonics Corp., claiming that the companies’ hip implant was defective, causing injuries and poisoning blood. The lawsuits involve the Accolade TMZF hip stem and LFIT anatomic V40 femoral head. Stryker already is facing more than 500 similar lawsuits over other artificial hip models, the Rejuvenate and ABG II modular-neck stems. According to the complaint, the titanium hip stem can corrode when it is used with the femoral heads, which are made from cobalt and chromium. When the metal corrodes inside the body, it can inflame tissue, ... Read More

Family says defective metal-on-metal hip implant caused mother’s brain cancer

A woman who had filed a lawsuit against Johnson & Johnson for its defective metal-on-metal hip implant has died of an aggressive brain cancer, a disease her family believes was caused by blood poisoning from her corroding artificial hip. Bharucha had broken a hip when she suffered a fall and in 2007 was fitted with Johnson & Johnson’s DePuy ASR hip replacement system. The surgery did not relieve her pain or help her regain her mobility. In fact, she grew increasingly worse. By 2011, a year after the device was recalled due to premature failures, Bharucha had revision surgery to ... Read More

More government oversight credited for jump in medical device recalls

The number of medical device recalls has doubled in the past 10 years, according to a new report, a result of more government oversight and manufacturers doing a better job of halting sales of defective devices, officials say. Yearly recalls jumped from about 600 in 2003 to 1,200 in 2012, according to the report, which was prompted in 2011 by the Government Accountability Office (GAO). The largest rise was due to radiological devices, such as MRI and CT scanners, which have been found to register false positives and increase the risk of cancer. A fifth of the recalls in 2012 ...

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

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

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

Lawyers ask FDA to investigate DePuy after alleged wrongdoing surfaces in ASR hip trials

Lawyers representing patients allegedly harmed by metal-on-metal hip implants have called upon the U.S. Food and Drug Administration (FDA) to investigate allegations of wrongdoing in DePuy Orthopedics, a division of Johnson & Johnson that manufactured and sold and subsequently recalled tens of thousands of defective metal ASR hips. The lawyers say new evidence emerged in testimony given during the first two bellwether personal-injury trials indicating DePuy broke federal laws when it concealed information that could have spared thousands of patients from injuries allegedly brought about by its ASR metal hip implants. That evidence had been sealed by court order until ... Read More
