Large diameter metal-on-metal artificial hips fail more often than other implants

Hip replacement surgeries are among the most performed surgical procedures, but in some cases the device fails, resulting in revision surgery to remove and replace the device. On average, artificial hips can last 20 years or more before being replaced, but one type and size of hip implant was found to fail more often than traditional hip implants. Last month, the Canadian Institute for Health Information released a report that studied the factors influencing how long artificial hip implants lasted. Researchers reviewed data from 56,942 surgeries throughout Canada (except Quebec) from 2003-2011. They found that metal-on-metal large-diameter modular implants in particular ... Read More

Smokers more likely to experience problems with hip replacements

Smokers who undergo hip replacement surgery take longer to heal after their operations, experience more complications, and are more likely to need revision surgery to repair or replace their implant, a new study reveals. The study was presented at the annual meeting of the American Academy of Orthopaedic Surgeons. Researchers reviewed data from 300 patients who underwent hip replacement surgery between 2007 and 2009. A third of the patients were smokers. Researchers found that patients who smoked had an 8 percent chance of their implants failing compared to 1 percent for nonsmokers. Of the nine revision surgeries among smokers, four ... Read More

Montana man awarded $8.3 million in first of 10,000+ DePuy metal hip implant lawsuits

Johnson & Johnson subsidiary DePuy Orthopaedics designed a flawed metal-on-metal hip replacement system and owes a retired prison guard from Montana $8.3 million in compensatory damages, a California jury decided in the first of more than 10,000 lawsuits regarding the devices to stand trial. Loren “Bill” Kransky sued DePuy arguing that the company failed to adequately test the device before marketing it in the United States. His lawsuit also claims the company covered up surgeon complaints of failures and considered redesigning the ASR model before ultimately deciding to stop making it in 2008. Johnson & Johnson recalled 93,000 DePuy ASR ... Read More

British MPs call for criminal inquiry into toxic DePuy hip implants

British MPs have called for an investigation into DePuy Orthopaedics after testimony from a U.S. court case revealed that the medical device company continued to sell defective artificial hip implants despite knowing for at least three years they were toxic to patients. DePuy, a subsidiary of Johnson & Johnson, recalled the ASR hip replacement system and hip resurfacing system after mounting reports that the device was failing at a higher than expected rate. The recall affected an estimated 93,000 people worldwide. The DePuy device was made to be more durable with all-metal parts, as opposed to plastic or ceramic parts ... Read More

Testimony: Johnson and Johnson ignored warnings that DePuy hip implant was defective

A doctor working as a consultant for Johnson & Johnson warned company executives in 2008 that the ASR hip replacement system made by J&J subsidiary DePuy Orthopaedics was poorly designed and suggested the company slow its marketing of the device until it discovered why the hip implant was hurting so many patients. The warning fell on deaf ears. It wasn’t until two years later, after several other doctor-consultants for the company pressed the issue with J&J that the consumer health care products giant issued a recall of the ASR artificial hip. In that time, literally thousands of patients worldwide underwent ... 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

FDA warns doctors, patients about risks associated with metal-on-metal hip implants

The Food and Drug Administration (FDA) released updated safety information to patients and health care providers about risks associated with metal-on-metal hip replacement systems and metal-on-metal hip resurfacing systems based on the agency’s current assessment of the implant and results from the June 2012 Orthopaedic and Rehabilitation Devices Advisory Panel meeting. The safety announcement advises health care providers to consider the benefit-risk profile of using metal-on-metal hip implants as opposed to an alternative hip system made with ceramic or plastic parts, to inform patients about the risks associated with the all-metal implants, and be aware of risk factors in the ...

Younger women with metal hips more likely to require revision surgery

Metal-on-metal stemmed hip implants should no longer be used in patients, and patients with these artificial hips should be carefully monitored, particularly young women whose hip implants have large diameter heads, according to a new study. The study, conducted by researchers from the Universities of Bristol and Exeter, and the Centre for Hip Surgery at the Wrightingdon Hospital in Lancashire, was based on data from the National Joint Registry in England and Wales. Researchers looked at 402,051 first total hip replacements using a stemmed implant between April 2003 and September 2011. They then singled out revision operations carried out on ... 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

Woman injured by recalled metal hip implant hires attorney

Sally Gration was barely 50 in 2006 when she was diagnosed with hip dysplasia and underwent a hip replacement surgery. The surgery went well and Sally began looking forward to a life without pain and disability. Artificial hips can last 20 years or more before they need to be replaced. But four years after surgery, Sally began experiencing excruciating pain in her hip. Around that same time she received word from the hospital where she had the surgery that the metal-on-metal hip implant she received had been recalled by the manufacturer because of safety concerns and high failure rates. Before ... Read More
