(NaturalNews) Between 200,000 and 300,000 hip replacement operations are performed each year in the U.S., mostly in people over the age of 60. However, according to the American Academy of Orthopaedic Surgeons (AAOS), five to 10% of these procedures are in patients younger than 50 — including women of childbearing age. Now comes a disturbing report that suggests women who have the metal-on-metal type of artificial hip joint and become pregnant could be putting their unborn babies at risk.
A study by researchers at Rush University Medical Center recently presented at the 2010 Annual Meeting of the American Academy of Orthopaedic Surgeons held in New Orleans revealed that expectant mothers with metal-on-metal hip implants pass metal ions to their offspring during pregnancy. The ions, it turns out, result from wear and tear as well as from corrosion as the parts of the artificial joint, called prosthesis, rub against one another.
