Metal Bearings in Hip Arthroplasty: What Have We Learned?

The International Society for Technology in Arthroplasty (ISTA)



Abstract

Metal Bearings in Hip Arthroplasty – What Have We Learned?

Large metal on metal bearings have come back to hip arthroplasty the past five to ten years with great promise to minimize wear debris, eliminate osteolysis, reduce dislocations and improve range of motion. While some of these claims have proven to be true, new problems have surfaced that threaten the success of these devices. Metalosis, “pseudotumours” and ALVAL (aseptic lymphocytic vasculitis associated lesions) are appearing. These lesions produce pain that is difficult to confirm on routine exam and xray but eventually lead to early revision surgery.

This paper will examine the advantages and complications of this hard bearing surface with a special look at complications, their prevention and management.
