    Description of Event or Problem · 1

    AN ARTICLE ¿RETRIEVAL ANALYSIS OF 240 METAL-ON-METAL HIP COMPONENTS, COMPARING MODULAR TOTAL HIP REPLACEMENT WITH HIP RESURFACING¿ BY A. MATTHIES ET AL REPORTS ON RETROSPECTIVE COMPARISON OF COMPONENT WEAR RATES AND PRE-REVISION BLOOD METAL IONS LEVELS IN TWO GROUPS OF FAILED METAL-ON-METAL HIP ARTHROPLASTIES: HIP RESURFACING AND MODULAR TOTAL HIP REPLACEMENT (THR). TOTAL 120 FAILED CURRENT-GENERATION MOM HIPS COUPLES (240 COMPONENTS ¿ 120 IN EACH) WERE COMPARED BETWEEN EXPLANTED MODULAR THRS (MEDIAN AGE -58, M: F=2:3) AND HIP RESURFACINGS (MEDIAN AGE -55, M: F=2:3). ASR IMPLANT WAS USED IN 26 AND 15 CASES OF MODULAR THR AND HIP RESURFACING GROUP RESPECTIVELY. FOLLOWING IMPLANTS WERE USED IN BOTH THE GROUPS: ADEPT (FINSBURY ORTHOPAEDICS), ASR (DEPUY), BHR (SMITH & NEPHEW), M2A-MAGNUM (BIOMET), CORMET (CORIN GROUP PLC), DUROM (ZIMMER), MITCH (STRYKER UK). MACROSCOPIC EXAMINATION REVEALED FINE SCRATCHING ON THE BEARING SURFACES AND IMPINGEMENT ON THE FEMORAL NECK OF THREE RESURFACING HEADS. EDGE-LOADED HIGH-WEARING ACETABULAR COMPONENTS HAVE BEEN SHOWN TO OCCUR ACROSS THE ENTIRE RANGE OF ACETABULAR INCLINATION FOR MODULAR THR AND HIP RESURFACING. ADVERSE ACETABULAR COMPONENT VERSION MAY BE AN IMPORTANT FACTOR RELATED TO EDGE LOADING IN THESE IMPLANTS WHICH HAD AN ACCEPTABLE INCLINATION ANGLE AND BE RESPONSIBLE FOR ELEVATED BLOOD METAL IONS. DISLOCATION, FRACTURE, INFECTION, LOOSENING AND UNEXPLAINED (PAIN) WERE REPORTED AS CAUSATIVE FACTOR OF THE FAILURE. NO CLARIFICATION WAS FOUND ON WHICH EVENTS WERE SPECIFICALLY PRESENT ON SPECIFIC PATIENTS.
