DePuy President resigns amid mounting hip-implant lawsuits

Johnson & Johnson has announced the resignation of DePuy Orthopaedics president David Floyd, who led the hip-implant manufacturing operation since 2007. DePuy has been grappling with recalls and lawsuits over it ASR XL Acetabular hip implant system and ASR Hip Resurfacing System, which have been implanted in about 40,000 Americans and an additional 53,000 patients worldwide. Johnson & Johnson says that Mr. Floyd is leaving “to pursue other interests outside the company,” but the timing of his departure, effective at the end of March, suggests Johnson & Johnson is seeking new leadership for DePuy as lawsuits against the companies mount. ...

Lack of testing, FDA shortcuts made DePuy hip recipients guinea pigs

The term “guinea pig” is often used jokingly by patients who feel that their medical treatment is underdeveloped or experimental. But when it comes to the Food and Drug Administration’s fast-track approval of certain medical devices such as DePuy’s ASR XL Acetabular and ASR Hip Resurfacing implants, “guinea pig” is sometimes an apt description. The FDA often approves medical devices without requiring proper clinical testing if the manufacturer demonstrates that the new unproven device is substantially similar to an already-approved one. This process, called the 510k process, spares the manufacturer thousands of dollars in clinical testing and usually takes just ... Read More

1 in 8 people with defective hip implant have had revision surgery

One in eight people who received the now-recalled DePuy Orthopaedics hip replacement systems have had to have surgery to remove and replace their implants because the devices were defective and were causing patients pain, according to Arthritis Today. Most hip implants can last a lifetime, but two systems made by DePuy have shown a higher than expected failure rate, resulting in the late August recall. The affected parts include the ASR XL Acetabular and the ASR Hip Resurfacing System. The Acetabular was approved by Food and Drug Administration (FDA) and has been in use in the United States. The resurfacing ... Read More

Recalled artificial hips were never tested for safety in clinical trials

Artificial hips manufactured by DePuy Orthopedics, a subsidiary of Johnson & Johnson, were never put through clinical trials to ensure they were safe, according to the BBC. Now an estimated 12 percent of the 93,000 patients worldwide who were fitted with the devices could experience problems and face a second surgery to replace defective parts. Last August, DePuy issued a recall on two of its artificial hip parts following reports that a higher than expected number of hip joints failed in less than five years after they were implanted. The recalled parts included the ASR XL Acetabular System and the ... Read More

Woman joins class action lawsuit as she waits for new artificial hip

Marlene Burles is finally on a 3-month-long waiting list to replace a faulty artificial hip that has been causing her problems for four years, but getting approval from the manufacturers and insurers of her defective hip replacement in order to have the surgery could delay her even more. “It’s just a disaster,” Burles told The Mercury newspaper. Burles is one of about 100 Australians who have joined a class action lawsuit against the artificial hip manufacturer, DePuy Orthopedics, a subsidiary of Johnson & Johnson. Last August, the companies issued a recall on hip replacement parts because they showed a higher ... Read More

Thousands may need revision surgery to replace bad artificial hip

Thousands of the 93,000 people who received artificial hips made by DePuy Orthopedics will have to have surgery to have their implants replaced because the products can dislocate, come loose, or cause bone fractures. The affected parts include the ASR XL Acetabular System and the ASR Hip Resurfacing System, both made by DePuy Orthopedics, a subsidiary of Johnson & Johnson. Most hip replacement systems can last up to 35 years with a failure rate of about 12 percent. However, studies show that DePuy artificial hips have the same failure rate in just five years after being implanted. The defective implants ... Read More

Patients with total hip replacements more susceptible to dangerous falls

Patients undergoing total hip replacements are more likely to have more serious falls than other orthopedic patients, and these serious falls occur earlier than most falls – two days postoperatively rather than 4 days, when most falls occur, according to a study presented at the 2010 Annual Meeting of the American College of Rheumatology. The study also identified factors involved in patient falls that could help hospitals devise strategies to reduce these types of falls. Researchers from the Hospital for Special Surgery in New York say the findings suggest that patients who undergo total hip replacements should be monitored closely, ... Read More
