    Description of Event or Problem · 1

    INFORMATION WAS RECEIVED BASED ON REVIEW OF A JOURNAL ARTICLE TITLED, " A MULTINATIONAL ASSESSMENT OF MOM BEARINGS IN HIP REPLACEMENT" WHICH AIMED TO EXAMINE THE INCREASING EVIDENCE THAT MANY METAL-ON-METAL (METAL ON METAL) BEARINGS, WHEN USED WITH LARGE FEMORAL HEADS IN CONVENTIONAL HIP REPLACEMENT AND SOME RESURFACING PROSTHESES, ARE ASSOCIATED WITH INCREASED RATES OF REVISION ARTHROPLASTY. REGISTRIES ARE THE MAIN SOURCES OF DATA ON METAL ON METAL PROSTHESES. AT THE RECENT INTERNATIONAL CONSORTIUM OF ORTHOPAEDIC REGISTRIES (ICOR) MEETING, DATA WAS PRESENTED FROM THE (B)(6) REGISTRIES. ALL REGISTRIES REPORTED AN INCREASED RATE OF REVISION FOR LARGE FEMORAL HEAD METAL ON METAL PROSTHESES WHEN PROSTHESES WERE AGGREGATED COMPARED WITH THE AGGREGATED DATA OF HIP PROSTHESES WITH OTHER BEARING SURFACES. THERE WAS ALSO EVIDENCE, HOWEVER, THAT THE OUTCOME VARIED, DEPENDING ON THE TYPE OF PROSTHESES USED, IN BOTH LARGE FEMORAL HEAD METAL ON METAL CONVENTIONAL HIP REPLACEMENT AS WELL AS RESURFACING HIP REPLACEMENT. PATIENTS WERE IDENTIFIED IN THE ARTICLE THAT UNDERWENT A TOTAL HIP ARTHROPLASTY ON AN UNKNOWN DATE. SUBSEQUENTLY, THE PATIENTS HAD AN AVERAGE REVISION RATE OF 2.2 PERCENT AT THREE YEARS POST-OPERATIVELY DUE TO UNKNOWN REASONS. THERE HAS BEEN NO FURTHER INFORMATION PROVIDED AND THE PATIENT OUTCOME IS UNKNOWN.
