    Additional Manufacturer Narrative · 1

    DEPUY HAS RECEIVED 108 ULTIMA TPS FEMORAL STEM EXPLANTS FROM THE (B)(6) ORTHOPAEDIC HOSPITAL. THESE CONSIST LARGELY OF COMPONENTS FROM A CLINICAL STUDY. THE EXPLANTED STEMS HAVE DISPLAYED SOME EVIDENCE OF CORROSION ON THE SURFACE OF THE IMPLANT. THIS HAS BEEN REPORTED BY THE KEY SURGEONS FROM THE (B)(6) IN A CLINICAL PAPER ((B)(4) NOVEMBER 2010). FOLLOWING PREVIOUS CLINICAL REVIEW IN MARCH 2007, DEPUY HAD PROVIDED INFORMATION TO USERS REGARDING OUR FINDINGS AND OFFERED GUIDANCE ON THE FUTURE CLINICAL MANAGEMENT OF PATIENTS. ON (B)(6) 2007 THE MHRA ISSUED A MEDICAL DEVICE ALERT TO USERS ((B)(4)). THE ULTIMA TPS HIPS SYSTEM IS NO LONGER AVAILABLE ON THE MARKET FOR CLINICAL USE. MOST OF THE EXPLANTS RECENTLY RECEIVED ARE FAILURES REPORTED IN CLINICAL PAPER AND WHICH LEAD TO THE 2007 MDA [1] (19 OF WHICH HAD PREVIOUSLY BEEN INVESTIGATED THOUGH THE COMPLAINTS SYSTEM). THEY WERE COLLECTED IN THE (B)(6) AND PASSED TO US FOR ANALYSIS IN 2011. A FEW ARE FROM FURTHER REVISIONS CARRIED OUT AFTER THE MDA FROM THE ORIGINAL COHORT OF PATIENTS. PREVIOUS INVESTIGATION CONDUCTED ON ULTIMA TPS FEMORAL STEM EXPLANTS HAS BEEN PERFORMED IN CONJUNCTION WITH (B)(4) UNIVERSITY AND IS DOCUMENTED ON RDR NUMBER 124. ADDITIONAL INVESTIGATION WILL BE DOCUMENTED THROUGH A RESEARCH PROJECT CONDUCTED AND SUPPORTED BY GOVERNMENT FUNDING THROUGH A KTP (KNOWLEDGE TRANSFER PARTNERSHIP) IN ACCORDANCE WITH A OUTLINE PROTOCOL (RESEARCH PROJECT NUMBER - (B)(4)). THIS ANALYSIS INCLUDES INVESTIGATION INTO THE REASON FOR THE CORROSION OF THE TPS STEM AND IS DUE TO COMPLETE AT THE END OF 2013. THE EXPLANTS WILL BE HELD WITH RD AS PART OF THE KTP INVESTIGATION AND UPON COMPLETION WILL BE HANDED TO QUALITY FOR ARCHIVE. A HEALTH HAZARD EVALUATION ((B)(4)) IS ONGOING AT THIS TIME. CORRECTIVE ACTION NONE AT THIS TIME. SHOULD ANY ADDITIONAL INFORMATION BE RECEIVED TO CHANGE THE OUTCOME OF THE PERFORMED INVESTIGATION, THE COMPLAINT WILL BE RE-OPENED.
