AAJ asks FDA not to protect artificial hip makers from liability claims

The American Association for Justice (AAJ), a plaintiff lawyers industry group, is asking the Food and Drug Administration (FDA) to prevent makers of metal-on-metal hip implants from using a proposed change in the medical device approval process to protect them against liability claims. Tens of thousands of lawsuits have been filed against manufacturers of all-metal artificial hips after the devices showed a higher than expected failure rate and in some cases began corroding inside the bodies of patients, endangering their health. Traditional hip replacement systems are made with ceramic or plastic parts. But in more recent years, artificial joint manufacturers ... Read More

Rochester’s DePuy metal hip lawsuit will serve as example for other lawsuits

A lawsuit filed by a Rochester, NY woman against the manufacturer of an all-metal hip replacement system will serve as the example for more than 7,000 similar lawsuits across the country. Ann McCracken filed a lawsuit against DePuy Orthopaedics and it parent company Johnson & Johnson after her DePuy metal-on-metal artificial hip failed prematurely, requiring her to undergo revision surgery to remove and replace the defective hip implant. Artificial hips are traditionally made with ceramic or plastic parts, but in the past decade manufacturers began making hip implants with all-metal parts. The design turned out to be flawed, resulting in ... Read More

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

Artificial hip makers pay less to surgeons after settling lawsuit

A 2007 lawsuit charging manufacturers of artificial hips with providing kickbacks to orthopedic surgeons for using their products, has resulted in fewer payments to surgeons the year following the lawsuit, according to a report released today by the Archives of Internal Medicine. Researchers reviewed data from Biomet Inc., Johnson & Johnson’s DePuy unit, Smith & Nephew Plc, Stryler Corp, and Zimmer Holdings Inc. for the years 2007 and 2008. They found that a total of 939 orthopedic surgeons received $198 million from the medical device companies in 2007. A year later, 568 payments were made worth $119 million, plus $109 ... Read More

British registry shows DePuy hip implants failure rate rising

An estimated one-fifth to one-third of patients who have received a metal-on-metal hip replacement system made by Johnson & Johnson subsidiary DePuy Orthopaedics have had the devices fail them, according to the National Joint Registry for England and Wales. The report suggests the problem with the artificial hips is even greater than first expected. The United States does not have an established registry for replacement joints, but reports to the Food and Drug Administration (FDA) have also indicated the DePuy artificial hips were failing at a higher than expected rate. The hip implants were recalled last fall, affecting an estimated ... Read More

DePuy hip implant recipient says he can’t remember how pain-free feels

Severe, unceasing pain and immobility has become a new way of life for many patients who received faulty hip implants. Ironically, patients who are experiencing problems with their defective hip implants elected to receive the devices because they thought they would make life better by reducing pain and improving mobility. Norman Sherrington, a 67-year-old U.K. citizen, is one such patient. Speaking on Dispatches, an investigative television program aired in the U.K., Sherrington said that he has endured constant pain ever since his 2006 surgery in which he received a DePuy ASR XL Acetabular (total hip) implant. “I can’t walk up ...

DePuy hip implant failure rate may be 4X higher than previously thought

New data suggests that the failure rate of DePuy Orthopaedics ASR hip replacement systems is as much as four times higher than previously thought. The implants were recalled in August 2010 after studies showed that the implants had a failure rate of about 13 percent after five years. Most hip implants have a 13 percent failure rate after about 35 years. The new information comes from the British Orthopaedic Association and the British Hip Society, which said data from four surgeons showed that the rate of revision surgeries to replace defective DePuy artificial hips ranged from 21 percent after four ...

DePuy hip recalls expose flaws in U.S. health care system

The U.S. health care system, often celebrated domestically as the best in the world, is woefully inadequate when it comes to protecting consumers from dangerous and/or defective medical devices. The FDA, for instance, allows many medical devices to be fast-tracked through the approval process if the devices are substantially similar to already-approved devices. Then, if those devices fail and have to be recalled because they weren’t properly tested, no single registry exists that can readily tell officials how many Americans are affected and who those people are so that they can be contacted. This is the story of DePuy’s recalled ... Read More
