Untested medical devices, treatments dangerous: Consumer Reports


Consumer Reports found some medical devices that have not been clinically tested, including defibrillators, joint replacements and even surgical mesh used to treat hundreds of thousands of women.

Dr. Stephen Tower is an orthopedic surgeon. When the arthritis in his hip became too difficult to bear, he opted for a metal-on-metal hip. But the new hip, he says, caused him so much pain, exhaustion and depression that he had to have it removed.

"The tissues around the hip had been destroyed and that metal debris was spreading down my thigh," said Tower.

Tower says normal friction in the artificial joint caused cobalt, a toxic metal, to be released into his body, leading to serious tissue, heart, brain and thyroid problems.

"This particular type of hip was called the ASR XL. It was made of chrome cobalt metal, but it was never clinically tested before the FDA cleared it to be sold," said Nancy Metcalf, Consumer Reports senior editor. "Because of high failure rates and complications like Dr. Tower experienced, it's now off the market."

While metal-on-metal hips have been widely criticized, a Consumer Reports investigation has found there are other dangerous devices that are being implanted.

"Hundreds of thousands of women have had mesh slings inserted to support internal organs as they age, like the uterus and bladder," said Metcalf. "Again, these products were never clinically tested before being marketed for this use."

The FDA's own database shows thousands of complaints about the mesh, including debilitating infections. Yet it's still on the market, not even classified as high-risk.

"We strongly believe that the FDA should require rigorous testing for implantable devices just like they do for prescription drugs now," said Metcalf.

Fortunately for Dr. Tower, after his metal hip was replaced with a plastic and ceramic one, he was eventually able to return to his favorite athletic activities.

Consumer Reports says creating a national registry is essential to be able to keep track of implanted medical devices and to alert patients if there is a problem. Currently there is no such tracking in the U.S., and it's estimated only a fraction of device problems actually do get reported.
