The FDA (U.S. Food and Drug Administration) will hold a two-day conference on June 27-28, 2012 to gather expert scientific and clinical advice on the risks and benefits of metal-on-metal (MoM) hip implant systems.
These MoM implant systems can in fall in one of two categories:
1. Total hip replacements consisting of a metal ball (femoral head), a metal femoral stem in the thighbone, and a metal cup in the hip bone (acetabular component).
2. Hip resurfacing systems consisting of a trimmed femoral head capped with a metal covering and a metal cup in the hip bone (acetabular component).
Last year, the FDA issued an order for hip implant manufacturers to collect more safety data on these systems after implantation, including data related to metallic ions in the blood. Now the FDA is considering whether to subject MoM hip implants to more rigorous premarket testing.
