Clinical Testing for Metal-on-Metal Prosthetics
There is an increased interest in the determination of chromium and cobalt blood concentrations in patients receiving metal-on-metal prosthetics. This presentation will highlight key issues surrounding the increased interest in testing and current regulations and guidelines. In addition, the pros and cons of several available specimen types will be discussed. Lastly, current literature regarding the use of blood samples to monitor metal-on-metal prosthetic wear will be presented.
Originally presented February 08, 2013 in Park City, Utah.

After this presentation, participants will be able to:
- List common health concerns associated with elevated cobalt or chromium blood levels.
- Compare heavy metal analysis in synovial fluid with venous sampling for monitoring metal-on-metal joint failure.
- Explain the relationship between the degree of metal-on-metal wear in joint replacements and heavy metal blood and serum concentrations.
