We are in the old Viking York in northern England. 45 operated hips have turned up on campus to hear the latest news about the dangerous, artificial hip, which they have received. Many of them must rely on crutches, all are afraid. They know that they walk around with a ticking bomb in the body. A bomb that can destroy their lives.

Marie Yuill has on his own body found out how wrong things can go. In 2006 and 2007, she set two so-called ASR hips from the manufacturer DePuy in. After constant pain for four years, she finally took them out. Then came the shock.

– The artificial hip had broken both tissues and bones. On the left side was 25% of muscle tissue away. I was so bad that I had to have a blood transfusion, she says.

And she is far from alone, says David Langton, who has studied the dangerous hip since 2007, and who for years have tried to get it off the market.

– It’s not a bomb suddenly explodes into the body of patients. But if doctors are constantly watching them and taking samples, so the metal can slowly degrade both tissues and bones, and when you open after some years, so it looks as if there is bombing, he explains.

The most frightening is that patients do not necessarily even feel a thing. Also in patients who have not had pain, then find doctors that have taken place decomposition.

The dangerous metal ASR hip by DePuy is made entirely of metal. This distinguishes it from the hip implants that were on the market until the zeros where the hip bone was made of metal while the bowl was lined with plastic.

old hip prostheses had the problem that the tiny plastic particles were worn away, and it could destroy the surrounding bone. Therefore launched many of the producers a metal to metal prosthesis. Then there was the problem of small plastic particles solved, but another showed up.

– Now we see instead that small metal particles are worn away and it breaks down tissue and bone around the hip, explains Thomas Joyce, there are bio-engineering at Newcastle University. And even more disturbing, so we can measure the metal in the blood of the hip operated.

The new metal on metal hips are made of such chromium and cobalt. The normal content of cobalt in the blood in humans is 1 mg per liter. liters. In people who have been implanted an ASR hip from DePuy, is measured far above 100

– Laboratory experiments have shown that cobalt and chromium may be carcinogenic. In patients we have seen a rash, fluid collections, tinnitus, hearing loss, memory loss and heart attacks. And so we do not know even long-term effects yet, says a worried Thomas Joyce.

Warnings Both he and David Langton has for years tried to shout both authorities up – no luck.

- Since 2007 we have participated in orthopedic conferences, written articles for medical journals, and we have held meetings with the manufacturer DePuy. But we were greeted by a wall of silence, and the doctors just kept putting the hip in new patients, says David Langton. I am embarrassed on behalf of the medical profession, he added.

According to Thomas Joyce then translates DePuy for approx. $ 40 billion. dollars a year. The company is part of a powerful industry that is accustomed to getting his way. It was David Langton to feel when he went to the British drug regulatory agency, the MHRA, with his knowledge.

– They said what do you want us to do? And I told them to remove it from the market immediately. We can not, the answer was. Then DePuy just sue us, says David Langton.

Early August 2010, the dangerous hip pulled from the market. Because the evidence of the many complications so overwhelming that it itself is the consequence.

Today, figures from the British hip register to one third of patients have hip removed within 6 years.

– But the numbers are a year old, says David Langton. Our latest figures show that it is 50%.
