Ten Cases Selected For MDL over Johnson & Johnson’s Metal-on-Metal Hip Implants

U.S. District Judge Ed Kinkeade, a Texas federal judge, has selected 10 cases for the next bellwether trial in the multidistrict litigation (MDL) over Johnson & Johnson’s metal-on-metal hip implants. They were selected from thousands of cases waiting their turn in the giant litigation. The judge conducted his own independent review of potential bellwether cases, all of which involve plaintiffs that claim the metal-on-metal hip design caused trillions of microscopic metal particles to shed with every step, which they say led to bone erosion, tissue damage, infection, inflammation and blood poisoning known as metallosis. The cobalt-chromium alloy socket-and-ball-head hip implant system has been ... Read More

The U.S. Department of Health and Human Services Adds Cobalt to List of Carcinogens

On Nov. 3, 2016 The U.S. Department of Health and Human Services (HHS) released the 14th Report on Carcinogens (RoC) that includes cobalt and cobalt compounds on its list of cancer-causing substances. The RoC is a public health document that is science-based and congressionally mandated, describing 248 listings of agents, substances, mixtures, and exposure circumstances that are known and confirmed carcinogens. The report advises that “intracellular release of cobalt ions from particles” is a key event related to toxicity and carcinogenicity, as seen the cases of metal-on-metal hip implant failure. Metal-on-metal hip implants are made primarily of cobalt and chromium alloy. Patients who have received this ... Read More

Lawyers say Medical Device Makers Pushed Metal-on-Metal Hip Implants ‘Aggressively’

During opening arguments in an multidistrict litigation(MDL) trial over allegedly faulty metal-on-metal hips made by DePuy Orthopaedics, a subsidiary of Johnson & Johnson, six plaintiffs say the manufacturer pushed their product “aggressively,” despite knowing that the metal-on-metal design was riskier than others that were available. The complaint alleges DePuy went as far as paying kickbacks to willing surgeons to encourage use of their hip implant, selling 150,000 of them in the 2000s. The hip device managed to evade standard regulatory review by going through a 510(k) FDA approval, which allows a device to be sold on the market as long as it ... Read More

‘The Bone – er, Joint – Collector’ studies artificial implant technology

Steven Kurtz, biomedical engineer and director of the Implant Research Center at Drexel University, is the proud owner of an unusual collection of more than 7,000 artificial knees, hips, and other implants from around the U.S. He receives boxes of discarded devices from 15 hospitals in eight states, all in the name of making artificial implant technology better. “We study the tough things that happen to good implants,” said Kurtz. Kurtz has found that the most common reasons for the failure of joint replacement are infection, a loosening of the device, or dislocation, specifically in hip replacements. It’s less common for the ... Read More

Live Satellite Testimony Permitted for Metal-on-Metal Hip MDL Trial

Live satellite testimony has been permitted by U.S. District Judge Ed Kinkeade for a trial in a multidistrict litigation (MDL) over metal-on-metal hip implants made by Johnson & Johnson and its subsidiary, DePuy Orthopaedics. In Texas court, DePuy executive Pam Plouhar is scheduled to give testimony via satellite video, as well as witnesses in Los Angeles and Minneapolis. “It’s a form of harassment. It’s court-sanctioned harassment,” said the co-chair of the life sciences and product liability practice groups at the attorney’s office defending the J&J and DePuy. “Courts and litigants have been relying on deposition transcripts and video for decades, so they’re not less reliable. They may ... Read More

U.S. Judicial Panel on Multidistrict Litigation Assigns New Judge to DePuy ASR Hip Implant MDL

Judge David A. Katz of the U.S. District Court for the Southern District of Ohio, who has been presiding over the ongoing DePuy Orthopaedics Inc. ASR Hip Implant Products Liability Litigation docket from the beginning in December of 2010, passed away in July at the age of 82. The MDL has been assigned a new judge by the U.S. Judicial Panel on Multidistrict Litigation. As of Sept. 2, Hon. Jeffrey J. Helmick has been assigned to coordinate pretrial proceedings. According to the New York Times, the ASR metal-on-metal hip made by DePuy Orthopaedics, subsidiary of Johnson & Johnson, has been dubbed “one of the biggest medical ... Read More

Metal Poisoning from Metal-on-Metal Hips Linked to Skin Rashes and Cardiomyopathy

Metal-on-metal hips are primarily made of cobalt and chromium. When these components rub together with normal use, the parts wear down and corrode, causing metal to leach into the surrounding tissues and bloodstream. Once in the bloodstream, the metal content can cause metal poisoning called metallosis. Side effects may include implant failure, necrosis (tissue and bone death), and organ damage. These side effects may require revision surgery to treat. Pseudo tumors are also a side effect of the metal poisoning. The tumors are soft tissue changes in the surrounding tissues and bone of the hip prosthetic. According to a study published June 2015, ... Read More

Kiwi Yoga Instructor Experiences Implant Failure Within Weeks of receiving Metal-on-Metal Hip replacement

Bernadette Rae, a 60-year-old yoga instructor in New Zealand, underwent a second hip replacement surgery when her ASR hip made by DePuy Orthopaedics failed. DePuy paid for Rae to receive a second surgery with a new ASR hip, another metal-on-metal hip design. Within weeks after the second surgery, Rae’s new hip began dislocating. Rae, unable to move around the house without a walking stick, was forced to sell her home and buy a flat that is suitable for a handicapped woman. She refers to her new home as a “granny flat.” Plagued with skin rashes, cramps and insomnia that she blames ... Read More

Orthopedic Surgeon Urges embracing new Technologies in Total Hip Replacements with Caution

In the last few years, there was a push toward accepting cobalt and chromium metal-on-metal hip implant designs as new-and-improved technology. But now the design is proving to have high revision rates. Some implants are failing in less than five years, when hip implants made from other materials such as ceramics or plastics have been known to last 20 years or more. This has resulted in a wave of lawsuits aimed at metal-on-metal hip manufacturers such as DePuy Orthopaedics, a subsidiary of Johnson & Johnson. Yasser Farid, MD, director of the Chicago Bone Metastases Center and a practicing orthopedic surgeon at the Chicago Center for Orthopedics ... Read More

Scottish Man’s Metal Hip Removed After Only Three Years leaving him Permanently Crippled

John Haldane was 68 when he received a new hip, a metal-on-metal design that he was told would last two decades. Three years later, the hip had to be removed, leaving him permanently crippled. “I’m disabled and this should not have happened,” Haldane said. “I just want the company which made the implants to take responsibility.” Now, 88 people who allege they were permanently injured by metal-on-metal hip implants are seeking compensation for the agony and problems they say they experienced from their new prosthetic. Their ages range from 30s to 80s, and each claim their lives have been ruined by the faulty device. They’re ... Read More
