Article title: Hidden Dangers: patients, doctors not informed of defective implants

By Spencer Woodman

This article begins with the story of Vijay Vojhala, an Indian man who received a Johnson & Johnson metal-on-metal hip in 2008. Vojhala’s implant was the DePuy Orthopaedics ASR hip system.

In 2011, Vojhala went to a medical product conference and found out that his hip replacement had been recalled in a handful of countries, including the U.S., over a year ago.

Soon after, Vojhala found out that his implant had shed metal particles that infiltrated his blood stream. Vojhala now has a limp and cannot work. His implant has a failure rate over 50 percent.

The article explains that the problem Vojhala had was due to the fact that, in many cases, medical implants are recalled or even banned in some countries, but they remain on the market in other countries. Additionally, it is very difficult for hospitals to locate patients who have received recalled implants.

After Vojhala’s hip was recalled around the world, it took India’s health authorities over three years to notify hospitals. By that point, Johnson & Johnson and India’s hospitals had lost track of who had received the hazardous implant.

Johnson & Johnson claimed that patient privacy laws prevented them from directly reaching out to patients who received their metal-on-metal hips.

Johnson & Johnson also claimed that they posted recall information on their website and hired third-party companies to tell patients that their implant had been recalled.

The article then goes on to explain that, when medical products are recalled, the process for notifying the public is not always effective. Sometimes a recall only requires labeling changes, and other times, a recall might require a product to be completely removed from the shelves. In other cases, manufacturers will stop sales after a recall but won’t admit any wrongdoing. Governments can also ban the sale of certain devices without even recalling them.

The author’s investigation found that there was no global database to search for device recalls, so the journalists of the ICIJ made one. The ICIJ’s database shows any implant that has been recalled or deemed dangerous in any country. They hope this resource will make it easier for patients to find out when their medical devices have been recalled in other places around the world.

A major problem the ICIJ found is that sometimes a product will be recalled in some countries but not others. One example of this is a metal-on-metal hip produced by Biomet. After studies found that Biomet’s implant was causing metallosis – a type of metal poisoning that affects internal tissue – Biomet notified doctors in Australia, the UK and other countries in Europe. But they did not notify any doctors in Canada or the US. The authors state that if the FDA had tried to recall the implant, American doctors would have known about the recall too.

The investigators interviewed a 43-year-old American man named Andrew Chappell, who had a Biomet metal-on-metal hip implant. At a doctor’s appointment, Andrew found out that his implant was injuring his bones. The implant eroded his bones so much that his femur cracked during a surgery he received in 2018, three years after Biomet’s implant was recalled in other countries.

Zimmer Biomet (the new official name for Biomet) did not respond to the journalist’s questions about the global recalls. The company simply stated that they “adhere to strict regulatory standards” and are “commit[ted] to operating a first-rate quality management system” around the world. They also stated that they work closely with the FDA.

When the journalists asked the FDA why they hadn’t recalled the Biomet hip even though other countries recalled it, the FDA said that they posted a general safety notification about metal-on-metal hips on their website in 2011. They said that, because they posted that notice online, they didn’t have to recall the Biomet hip.

Could we somehow fix the worldwide gaps in medical device recalls? It turns out there are efforts around the world to streamline and improve how patients are notified of implant recalls.

The investigators interviewed Harold Paz, the vice president of Aetna, a major US health insurance company. Paz is advocating for a system that would track patients who are implanted with medical devices like metal-on-metal implants. This would make it easier to inform patients when their devices are recalled. Paz believes that if automobile manufacturers can keep track of their owners, then medical providers should be able to keep track of patients who receive medical implants.

They also interviewed Carl Heneghan, a health researcher in the UK. He said that databases to track joint replacements have taken off much faster than databases for other types of medical devices, most likely because of the high failure rate of joint implants like metal-on-metal hips.

However, this is really only true for the UK and Canada. The US and India, for example, have not really taken steps to track joint implants through device registries. However, after the Johnson & Johnson hip implant scandal, the Indian government “is considering implementing its own implant registry.”

On that same note, the authors spoke with Dr. Henrick Malchau, an orthopedic surgeon from Sweden who has been pushing to create worldwide implant registries. He said Australia’s implant database was the reason government health agencies figured out that Johnson & Johnson’s hip implant was dangerous. The information from the database was also instrumental in notifying patients and doctors of the device’s hazards. Because the database tracked all the patients who received implants, it was easy to let them know that the metal-on-metal hip was dangerous.

In closing the article, the authors revisit the story of Vojhala, who received the hazardous Johnson & Johnson hip implant in India. He says that better systems to notify patients about implant problems are “badly needed.” To this day, Vojhala suffers from decreased mobility, vision problems, and heart problems because of his implant. These health complications have left him unemployed. He says that if he had known about the recall when it first happened, he could have avoided the complications and “a lot of pain.”
