Welcome Back

The Hip Talk Discussion Forum was hacked a few weeks back. It has taken me a long time to fix it. The only backup I could use was way back to April 2020. All members and posts up to that date are available. Anything newer has been lost. I am sorry, but that has been the only way to get things up and running again.

Chelating agents for metallosis?
« on: April 01, 2013, 08:17:26 PM »
Is there something that binds to cobalt and chromium to neutralize any excessive cobalt and chromium ions that may be released by not only Hip replacements but also Hip resurfacing? 
Just wondering??  They can do it with excessive lead in the body so why not CO?
For any chemists in the group...  :)

Try reading the above link (Pat originally forwarded it to me in Sept 2012).

This device, I believe, undergoes a vapour spraying process to prevent, rather than neutralise, the release of cobalt and chromium ions.

It's a german made device that is being used in Wales, UK, and other European countries. Male and female hippies on this site have been fitted with it.

Hi Claudia - chelating agents that are successful for some chemicals are not so much for others.

As an example, EDTA, a well known chelation treatment compound is effective in chelating and allowing the body to excrete lead, zinc, cadmium and calcium, but has no effect on cobalt, chromium or copper. It also acts to increase the retention of magnesium.

So any chelation treatment should bear in mind the effects on the body. You obviously want to get rid of metals like lead, which is so detrimental, but care should be taken with removing calcium  :o

Like with any other chemical treatment, I think you have to weigh the positives and negatives.
