Titanium Debris from Artificial Joints May Trigger Painful Inflammation

A new study found titanium particles that flake away from artificial joints through normal wear and tear may cause painful inflammation, according to a University of Medicine and Dentistry of New Jersey news release.

In the past, studies have attributed inflammation to bacteria that stick to the titanium particles and cause an immune response. However, researchers found the titanium particles themselves trigger inflammation in mice. Researchers also pinpointed the type of inflammatory response as Th2 response, which is typically associated with allergic responses and parasitic worm infections.
