Metal-on-metal hip implant settlement cuts Into Stryker Earnings

Profits for Stryker, a medical device manufacturing giant, have taken a 2.3 percent cut year-over-year when projections had predicted they’d be up by 14.1 percent. This is likely due to the number of lawsuits regarding the company’s Rejuvenate or ABG II modular metal-on-metal neck hip stems. Information about the earnings came about a month after Stryker announced that Howmedica Osteonics, its subsidiary, had reached a settlement with patients who required revision surgery to correct problems with their new Rejuvenate or ABG II metal-on-metal hips. The metal-on-metal hip implant designs, made by a number of medical device manufacturers such as Wright Medical, DePuy Orthopaedics and its parent company Johnson & Johnson; Smith & Nephew, and Zimmer Biomet ...

Johnson & Johnson Plans to Appeal $1 Billion hip implant verdict

It’s been a little over a month since DePuy Orthopaedics and its parent company, Johnson & Johnson, were handed a $1 billion verdict over their metal-on-metal hip implant system that has been known to shed metal debris. The federal jury found J&J responsible for failure to warn about the potential hazards linked to their hip implant products in the third bellwether trial of the multidistrict litigation (MDL). The verdict covers $30 million in damages and $1 billion in punitive damages. J&J and DePuy now plan to appeal the verdict, claiming they were not allowed to “properly and fairly defend against ...

European Medical Device Regulations Tightened Due to Metal-on-Metal Hip Implant Safety Concerns

New medical device regulations (MDR) have been put in place by European Parliament after four years of negotiation. The decision to tighten regulation was spurred by safety concerns over breast implants and metal-on-metal hips. The regulation amendments are expected to begin in early 2017, and medtechs will be allowed three years to comply. If the medical products fail to meet the new regulation standards, the manufacturer will lose their CE rating, which allows legal marketing of the product. The new regulations include stricter rules regarding clinical trials, quality management, and marketing necessities such as product labeling and design. Regulators will now inspect Class ...

Large-Diameter Metal-on-Metal Hips Sparked Study on Metal Allergy

A Missouri orthopedic surgeon and colleagues have initiated a study that identifies the patients who underwent total joint replacement reporting a metal allergy. The study analyzes the effect of voluntary reported metal allergies on the clinical outcomes following the surgery. Dr. Denis Nam, recipient of the Orthopaedic Research and Education/Current Concepts of Joint Replacement (CCJR) Clinical Award Paper, along with other researchers, gathered retrospective data from 589 patients who received total knee arthroplasty (TKA), and 906 patients who received total hip arthroplasty between the years of 2009 and 2011. Before January 2010, the incidence of self-reported metal allergy was 1.7 percent. After January 2010, the incidence was 4 percent. ... Read More

Patients Experience Cobalt Poisoning after Hip Replacement Surgery

Dr. Steve Tower specializes in hip, knee and shoulder surgery as well as general orthopedics and trauma care. In 2006, Tower had hip replacement surgery and received a metal-on-metal hip implant design made of chrome cobalt. A year after the hip was replaced, he began experiencing pain. Having replaced “about a thousand” hips in patients himself, Tower knew this was not the norm. Remembering that the hip was made of cobalt, he decided to have his blood levels checked. He found the cobalt levels in his blood to be extremely high. Three years after replacement, the hip became so painful that revision ... Read More

Man diagnosed with Cobalt Poisoning After Receiving Metal Hip Implant

A patient with severe heart failure was referred to the Marburg University clinic in Germany in 2012. A possible cause was coronary artery disease, but after further examinations, the medical team ruled it out. However, some of the medics working on the case noticed a few notable similarities between the patient’s symptoms and the symptoms of a patient on House, a TV series in which British actor Hugh Laurie plays the lead character, Gregory House, M.D. On the TV show, a patient was experiencing strikingly similar symptoms and was diagnosed as having cobalt poisoning, which was caused by the debris shed ...
