Doctors have known for several years that some hip devices, in which both the ball and cup are made of metal, were failing at faster rates than other hip implants. Now, new research is confirming this information and claiming that the problem can cause trouble for many years to come, even after removal.
“This is a serious problem in the USA,” said Mathias Bostrom, an orthopedic surgeon at the Hospital for Special Surgery in New York City. “Some implants have a worse record than others, but almost all the metal-on-metal implants have issues.”
Damage to the body occurs, Bostrom said, when the implant pieces move against each other and metal debris breaks off, lodging in nearby soft tissue and bone and entering the blood. Inflammation and tissue death can occur around the joint, and problems affecting the heart and nervous system, although rare, can develop from toxins entering the blood, the FDA said.
But, this may not be the worst, according to the U.K.’s Telegraph newspaper, a medical study underway is expected to reveal that side effects of metal-on-metal hip replacements can cause genetic damage, which could lead to an increased risk of cancer.
