Corroding metal hip implants may cause DNA damage, medical problems

Corroding debris from failing metal-on-metal artificial hips release Cobalt 2+ ions in surrounding tissue, which cause inflammation and may also do damage to DNA which could result in medical complications including cancer, according to researchers from Imperial College London and Ohio State University. Metal-on-metal hip replacement systems were introduced in the early 2000s as a more durable alternative to traditional ceramic or plastic hip implants. But the devices began failing at higher than expected rates after just five years or less. What surgeons found is that the failures were triggered by inflammation in the tissue surrounding the implant. This inflammation was ... Read More
