Hip implant failure 29 percent higher in women, new study finds

A new study of more than 35,100 patients who were surgically implanted with artificial hip devices reveals that women are much more likely than men to require revision surgery within the first three years to correct problems with the implant. The research, published in JAMA Internal Medicine, was funded by the U.S. Food and Drug Administration (FDA) and comes amid a torrent of lawsuits against Johnson & Johnson and its orthopedic device unit DePuy alleging the company’s ASR all-metal hip devices caused serious, sometimes catastrophic, injuries in patients. Of the 35,140 total hip anthroplasty (THA) patients studied, female subjects were ... Read More

Hip implant failures more likely in women than men

Women are more likely to need revision surgery to remove and replace their artificial hips than men, according to a study published in JAMA Internal Medicine. The study, funded by the Food and Drug Administration (FDA) focused on the high number of failure rates in hip replacement systems. Researchers found that regardless of the type of hip implant used, hip replacements in women were more than 30 times more likely to fail than those implanted in men. Research involved more than 35,000 people who received hip replacement surgeries from one of 46 different hospitals in the Kaiser Permanente health system. ... 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

Johnson and Johnson recalls another metal-on-metal hip implant

Johnson & Johnson is recalling thousands more metal-on-metal hip replacement systems because of early failures. The recall comes 2 ½ years after the company recalled the DePuy Orthopaedics ASR metal-on-metal hip replacement system and hip resurfacing system for similar problems, an event that brought to light serious flaws with all-metal hip implants. Most artificial hips are made with plastic or ceramic parts. During the past decade, some medical device companies began using all-metal parts. It turned out to be a grievous design flaw. The metal parts were prone to corroding inside the body, leading to early failure of the devices, ... Read More

Emails presented in DePuy trial show marketer’s concerns over ASR hip implant safety

Internal communications among DePuy executives discussing how to handle metal-on-metal ASR hip problems were presented to jurors hearing the first of several thousand personal-injury lawsuits involving the faulty devices to go to trial. DePuy is a subsidiary of Johnson & Johnson. According to the records presented, on September 18, 2009, Paul Berman, DePuy’s director of hip marketing, sent one of many emails to company officials warning that the metal-on-metal hip devices should be recalled given the alarming number of reports that the devices were failing. Mr. Berman wrote that he wanted to “reiterate my concerns” about the safety of the ... Read More

Testimony in first DePuy trial indicates company failed to act on ASR hip warnings

Court documents and the recent testimony given by DePuy officials during the first ASR metal hip case to go to trial indicate the company took very little action, if any, to warn prospective patients about the serious risks its all-metal hip implants posed. DePuy Orthopedics, a division of the Johnson & Johnson health care conglomerate, started selling its ASR Acetabular and Hip Resurfacing Systems in 2003 after the devices were fast-tracked through the U.S. Food and Drug Administration’s approval process. By 2005, DePuy began receiving complaints about the all-metal devices, which were designed to outlast conventional hip implants made with ... Read More

Failure of metal-on-metal hip implants causing pain for patients

Scott Ebert, 48, was so happy to experience relief from pain after receiving a new artificial hip made by Stryker that he named his new puppy after the medical device company. But two months later, Ebert was singing a different tune. Ebert’s artificial joint began slipping, causing his leg to give out unexpectedly. Sharp pains stabbed at his foot, and a sizeable bruise covered his calf. His hip burned with pain, his ears rang. Ebert rattled off an odd list of symptoms that only baffled his doctor, until he drew Ebert’s blood. Ebert’s artificial hip, known as the Rejuvenate, was ... Read More

First DePuy hip trial underway in Los Angeles

The first of several thousand personal-injury lawsuits accusing Johnson & Johnson of knowingly making and selling faulty metal-on-metal hip implants commenced Friday in California Superior Court in Los Angeles. Plaintiff Loren Kransky, a former North Dakota prison guard, received metal-on-metal hip implants made by Johnson & Johnson’s DePuy Orthopedics division in 2007 to relieve arthritis pain. But not long afterward, Mr. Kransky, 64, began experiencing many of the complications reported by others who received DePuy ASR implants: pain, swelling, difficulty walking, and a number of symptoms related to metal poisoning. On the first day of the trial, the plaintiff’s lawyer ... Read More

Johnson and Johnson internal analysis shows recalled hip implant could have 40 percent failure risk

Not long after health care giant Johnson & Johnson and its subsidiary DePuy Orthopaedics issued a worldwide recall of the ASR hip replacement system and ASR hip resurfacing system due to a higher rate of premature failures than competitive devices, the company launched an internal analysis of its recalled metal-on-metal devices. What the company discovered is that the devices were far more defective than first thought. The analysis showed that the hip implants could be expected to fail within five years in an estimated 40 percent of patients who received the all-metal hip. It was data from the National Joint ...

DePuy continued to make and sell faulty metal hip implants for months before recall

DePuy Orthopedics and its parent company Johnson & Johnson knew in 2008 its ASR metal hip implants were failing early at unusually high rates, but they continued to make the devices for several more months before finally recalling them in August 2010, newly released court documents show. The findings were contained in a number of pretrial depositions and internal company records unsealed before the scheduled start of the first trial over DePuy’s faulty implants on Friday. The case, which will be tried in California Superior Court in Los Angeles under Judge J. Stephen Czuleger. The trial will likely reveal a ... Read More
