Company aware of hip implant danger

An international hip implant company was aware questions were being asked about the dangers of its metal on metal implants years before they were subject to a worldwide recall, including in New Zealand, it has been revealed.

Consumer advocate group for drug and medical device recall victims, US Drug Watchdog, has advised all recipients of Depuy metal on metal hip implants to get blood tests for cobalt and chromium levels after concerns the metals were wearing away from the joint and entering the blood stream.

Depuy, a subsidiary of Johnson & Johnson, recalled the implants in 2010 after data showed surgeons were replacing them at a rate twice the industry average.

Some 500 New Zealanders have the implants.

A US court is currently considering whether patients should be compensated for the faulty implants, and as part of the case it has been revealed that Depuy knew about issues much earlier than when they recalled the implants.

Depuy was reportedly told as early as 2006 of problems with the implants, with leading British orthopaedic surgeon David Beverland warning in emails that patients were suffering, the Daily Telegraph newspaper reported today.

It was not clear what specifically he was warning Depuy about.

The Wall Street Journal reported that Depuy company figures showed problems with the “survival rate” of the implants in 2007. The implants were supposed to last a lifetime.

In March 2008, the company’s marketing team discussed ways of using different data to market the implant which meant it could claim a 99 per cent success rate.

The implants were finally recalled in 2010 after data showed surgeons were replacing them at a rate twice the industry average.

A company analysis found that nearly 36 per cent of the implants were expected to fail within five years.

Last year up to 50 New Zealand patients who received the implants instructed a London barrister to seek compensation in the UK where the implant was made. ACC legislation prevents them from suing for pain and suffering here.

New Zealand man James Elliott is part of the group claiming compensation in Britain.

Today he said the lawyers had so far won the right to claim, but Johnson & Johnson now had the right to argue in court that the claims should be brought in New Zealand.

Mr Elliott said there was a “narrative” US lawyers had been building for a while and “that is exactly this, that the company knew for a long time about the dangers”, he said.

“It’s not the first time I’ve heard of so-called smoking gun documents coming out of the discovery process that they’re now well under way with in America.”

It fit into the scheme of Johnson & Johnson and particularly the way it had handled the case, he said.

US Drug Watchdog said it had been dealing with the metal on metal “mess” for two years and had known about the cobalt and chromium poisoning for at least 18 months.

But the US Food and Drug Administration had only just said it was concerned about tissue damage related to elevated levels of cobalt and chromium, which prompted the patient advocate’s advice to recipients.

About 140,000 Americans have had the implant, and about 10,000 Britons had been fitted with it.
