Elevated Levels of Cobalt and Chromium Found in Offspring of Moms with Metal-on-Metal Hip Implants

This is kind of scary considering how "popular" hip plants are getting. Makes you think of other things we just stick in the body (from Newswise)
Newswise — Women with metal-on-metal hip implants, where both the ball of the joint and the surface of the socket are made of metal, pass metal ions to their offspring during pregnancy, according to a study by researchers at Rush University Medical Center. The ions are the result of wear and corrosion as the metal parts rub against one another.

The data showed a correlation between levels of cobalt and chromium – components of metal implants – in mothers and their babies at the time of delivery.

The study will be presented March 9 at the 2010 Annual Meeting of the American Academy of Orthopaedic Surgeons in New Orleans.
