The safety of metal-on-metal hip replacements is under scrutiny as the US Food and Drug Administration holds hearings starting today on the subject after years of reports of problems with the devices. The nearings come after the UK's Medicines and Healthcare Products Regulatory Agency in March suggested yearly blood and MRI tests for patients with metal hips, citing possible metal poisoning and increased cancer risks as concerns. This animation illustrates the different types of hip replacements — plastic, ceramic and metal — and how debris caused by hip movement may adversely affect the body.
