[Metal-on-metal hip arthroplasty]

Abstract

In Denmark 4,456 metal-on-metal (MoM) hip prostheses have been implanted. Evidence demonstrates that some patients develope adverse biological reactions causing failures of MoM hip arthroplasty. Some reactions might be systemic. Failure rates are associated with the type and the design of the MoM hip implant. A Danish surveillance programme has been initiated addressing these problems.
