Metallosis is the build-up of metallic debris in the body’s soft tissues. This condition can be caused when the metallic components of implants, such as joint replacements, wear against one another causing metal particles to break off.
When metal particles around the metal-on-metal implants damage the bone and/or tissue around the joint, it is sometimes referred to as an adverse local tissue reaction (ALTR) or an adverse reaction to metal debris (ARMD). These reactions to metal debris can cause a joint implant to become loose or painful, and a revision surgery may be necessary.
Metallosis can also cause metal ions from the implant or particles to get into the bloodstream, which may result in symptoms or illness in other areas of the body, including the possibility of cancer if the metal implant contains cobalt or chromium. This is called cobaltism, and this condition may include adverse effects on the heart, nervous system and thyroid gland.
Symptoms of metallosis include:
- Pain in the groin, hip or leg (for hip implants) or around the site of the implant
- Pseudo-tumors (a mass of inflamed cells made of collected fluids that resembles a tumor)
- Osteolysis (destruction of bone tissue)
- Systemic effects related to metal hypersensitivity

The FDA announced a recall of DePuy ASR total hip system in August 2010. This recall was based on new, unpublished data obtained from the UK joint registry, which indicated the revision rates within 5 years were approximately 13 percent. Shards of metal from the DePuy ASR total hip system have been found to grind off, causing metallosis and resulting in increased levels of the dangerous metal ions.
