Many more revision surgeries occur in patients with all-metal hip implants

Nearly 75 percent of revision surgeries to remove and replace a hip replacement within five years of initial implantation occur in patients who received a metal-on-metal device, according to a Canadian study. Researchers pored through data involving 60,000 hip replacements performed across Canada between 2003 and 2011. They found that the need for revision surgery was greater in patients who had large-diameter modular metal-on-metal implants compared to patients who had more common plastic devices. Traditional hip replacement systems are made with ceramic or plastic parts, and can last 20 years or more before needing to be replaced. In the past ... Read More

3.4 million Japanese automobiles recalled due to faulty airbags

Four Japanese automobile makers are recalling 3.4 million vehicles sold worldwide because the airbags could catch on fire or injure passengers. The airbags were manufactured by Takata Corp., the world’s second largest supplier of airbags and seat belts. This is the largest airbag recall Takata has ever issued. The recall involves vehicles made by Toyota Motor Corp, Nissan Motor Co, Honda Motor Co Ltd, and Mazda Motor Corp. Toyota, Honda and Nissan said they are not aware of any injuries or deaths caused by the defective airbags. The problem is that during an accident the front passenger seat airbag may ... Read More

FDA proposes requiring makers of metal hips to submit premarket approval applications

The Food and Drug Administration (FDA) is proposing requiring manufacturers of metal-on-metal total hip replacement systems to submit premarket approval applications in order to assess risks associated with the devices. The proposed order was announced Thursday along with updated safety information and recommendations for patients and health care providers about illnesses and injuries associated with the devices. Metal-on-metal hip replacement and resurfacing systems, unlike traditional hip systems made with ceramic or plastic parts, have a metal ball that moves within a metal socket. This movement can cause bits of metal debris to release into the joint space, causing soft tissue damage ... Read More

Patients with metal hips should be checked by doctor annually

People who have received metal-on-metal hip replacement systems should be checked by a doctor every year for as long as they have the implant to ensure the implant isn’t failing or poisoning their blood, says the UK regulator of medical devices. Metal-on-metal hip implants were introduced a decade ago as a more durable artificial hip. Traditional hip implants are made with plastic or ceramic parts, but several manufacturers began offering all-metal versions. The design turned out to be a major flaw. Most hip implants can last 20 years or more, but the newer metal-on-metal devices were beginning to fail at a ... Read More

Man files lawsuit against makers of recalled metal hip implant

“It started to feel a bit clunky and was grinding and then it started to squeak very loudly – loud enough for people in the street to be startled and stare at me,” Chris Monk told the Evening News of his artificial hip. “I was in so much pain and could barely walk a few yards when it was at its worst.” Monk had scans that showed his all-metal hip implant was defective and had damaged his flesh. It had also dropped bits of metal debris inside his body that seeped into his bloodstream causing a type of blood poisoning ... Read More

Johnson and Johnson completes merger with troubled artificial hip maker

Johnson & Johnson has completed its acquisition of Synthes, Inc. and will integrate Synthes with its subsidiary DePuy Orthopaedics to establish the DePuy Synthes Companies of Johnson & Johnson. The deal was sealed with $19.7 billion in cash and stock. “The completion of the Synthes acquisition creates the world’s most innovative and comprehensive orthopaedics business and reflects our long-standing strategy of leadership within attractive health care markets,” said Alex Gorsky, Chief Executive Officer, Johnson & Johnson. “The combination of these two respected leaders — Synthes and DePuy — will enable us to better serve clinicians and patients worldwide, bring new ...

FDA advisory panel to review safety of metal-on-metal hip implants

The safety of metal-on-metal artificial hips will be investigated by a Food and Drug Administration (FDA) expert panel this June, according to a press releases issued by the agency. The hip implants have come under scrutiny over the past few years after mounting complaints from patients and studies that show the devices are prone to premature failure and can poison patients as they wear over time. FDA expert panels are assigned to review drugs and medical devices and make recommendations on corrective steps, whether it is to order stronger warnings about a product or ban it from the market. The ... Read More

Lawsuit filed against metal hip device manufacturer

A woman has filed a lawsuit against the makers of her artificial hip after the device allegedly popped out of joint and caused further damage to her body. The lawsuit was filed against Wright Medical Technology Inc. and Wright Medical Group, makers of the Wright PROFEMUR Total Hip System, a brand of metal-on-metal artificial hip. According to the lawsuit, the defendant underwent total hip replacement surgery on her right hip in March 2007. Shortly after being implanted with the all-metal hip, the woman began to experience pain and started walking with a limp. In July 2011, the defendant’s hip popped ... Read More

Study indicates metal-on-metal hip implants prone to failure

Surgeons should stop using metal-on-metal hip implants because they are prone to failure and may seep toxic metals into patients’ blood, say researchers who conducted safety studies on various hip replacement systems. The study was published this week in The Lancet. Hip implants are traditionally made with plastic or ceramic parts. But newer models have been designed with all metal parts. The all-metal devices have made news in recent months because of reports of early failures and blood poisoning from the metal components. Determining the failure rate is practically impossible in the United States because there is no joint registry. ... Read More

Researchers warn doctors not to use metal-on-metal hip implants

Researchers who conducted studies on metal-on-metal hip implants are asking doctors to stop using the devices because they believe they are much more likely to need repair or replacement, and may leech toxic metals into patients’ bloodstreams. The study, funded by the National Joint Registry of England and Wales, was published online this week in The Lancet. The study involved data of more than 400,000 hip replacement surgeries from the National Joint Registry between 2003 and 2011. More than 31,000 of the surgeries involved metal-on-metal hip implants. The others involved more traditional plastic or ceramic devices. Researchers found that after five ... Read More
