FDA Orders More Data on Metal Hip Implants
Metal-on-metal hip implants are used in about one-third of the 250,000 hip replacement surgeries performed each year according to a recent New York Times report. In early May 2011, the FDA issued 145 orders to 21 manufacturers of metal-on-metal hip implants ordering post-market surveillance studies due to serious safety concerns. The concerns include higher-than-normal revision surgery rates, increased risk of tissue necrosis surrounding the implants, and dangerous increased levels of metal ion levels (cobalt, chromium) in the bloodstream of persons implanted with metal-on-metal hip implants. Metallic debris generated from metal-on-metal hip implants can cause damage to the bone and surrounding tissue which can cause the implant to loosen and lead to severe pain. A recent editorial in a medical journal for orthopedic surgeons, The Journal of Arthroplasty, urged doctors to use the metal-on-metal devices only with “great caution, if at all.”
