Case Report in the Journal of Bone and Joint Surgery

exerpt taken from a web post

A case report, focusing on cobalt levels in DePuy hip replacement patients, was published on October 29, 2010 in the Journal of Bone and Joint Surgery by Dr. Stephen S. Tower, an orthopedic surgeon practicing in Alaska. Dr. Tower first notes that a serum cobalt level greater than 5 µg/L is considered toxic. This article discussed two 49 year old men who underwent hip replacement using the DePuy ASR System. Surprisingly, one of the men was Dr. Tower himself. In the first case, the serum cobalt level 36 months after the hip replacement surgery was 122 µg/L. In the other man, the serum cobalt level one year after surgery was 23 µg/L, and the cobalt level in his joint fluid at 40 months after the surgery was 3300 µg/L.

Dr. Tower pointed out that people with metal on metal hips can develop excess cobalt levels even if the hips are not causing any pain. The symptoms of excess cobalt that the men in Dr. Tower’s report experienced included fatigue, anxiety, headaches, hearing loss, ringing of the ears, tremors, cognitive decline and visual impairment.

Side comment from connie:  Blood work is needed to determine the levels of cobalt and chromium in your body. It is consistantly published that if it is discovered that you have concentrations greater than 7 parts per billion, you would need to have a second bout of blood test in three months.  Interesting descrepancy on the view of toxicity levels!
