    Additional Manufacturer Narrative · 1

    EXAMINATION OF THE REPORTED DEVICES WAS NOT POSSIBLE AS THEY WERE NOT RETURNED. A SEARCH OF THE COMPLAINTS DATABASES ON PRODUCT LOT 1046008, 1077816 1082947 IDENTIFIED NO PREVIOUS COMPLAINTS. A SEARCH OF THE COMPLAINTS DATABASES ON PRODUCT LOT 1069478 IDENTIFIED ONE PREVIOUS COMPLAINT THAT WAS RAISED REGARDING NECROSIS AND METALLOSIS. IT WAS CLOSED WITH AN UNDETERMINED CONCLUSION. THE PATIENT UNDERWENT A RIGHT TOTAL HIP REPLACEMENT ON (B)(6) 2003. IT WAS NOTED DURING THE PROCEDURE, THE NATURAL FEMORAL HEAD WAS IN "GROSS ANTEVERSION AND THE ACETABULUM WAS DYSPLASTIC MAKING THIS A COMPLEX PRIMARY. THIS MAY EXPLAIN THE SUPERIOR POSITION OF THE SHELL AND HEAD CENTRE WHEN COMPARED TO THE CONTRALATERAL. THERE IS INSUFFICIENT INFORMATION AVAILABLE TO REACH A ROOT CAUSE AS THE REASON FOR REVISION IS UNCLEAR, NO PRODUCT HAS BEEN RETURNED FOR REVIEW, NO HISTOLOGY HAS BEEN PROVIDED AND NO REVISION NOTES ARE PRESENT. THIS WAS A COMPLEX PRIMARY AND THE IMPLANT POSITION DIFFERS TO THE LANDMARKS ON THE CONTRA-LATERAL IN TERMS OF HEAD CENTRE, CUP POSITION, OFFSET AND POSSIBLY LEG LENGTH. THE PATIENT WAS ADVISED NOT TO LIFT ITEMS FROM LORRIES, OR, FROM THE FLOOR. BASED ON THE INABILITY TO DETERMINE ROOT CAUSE, THE NEED FOR CORRECTIVE ACTION HAS NOT BEEN INDICATED. DEPUY CONSIDERS THE INVESTIGATION CLOSED AT THIS TIME. SHOULD THE PRODUCT AND/OR ADDITIONAL INFORMATION BE RECEIVED, THE INVESTIGATION WILL BE RE-OPENED.
