    Additional Manufacturer Narrative · 1

    VISUAL INSPECTION OF THE MODIFIED 5.5 ROD BENDER SET, PRODUCT CODE 6983-26-474, LOT NO: G0407, FOUND ON THE RIGHT HAND SIDE BENDER THAT BOTH DISTAL TIPS BROKE OFF. THE BROKEN PIECES WERE NOT RETURNED FOR EVALUATION. SIGNIFICANT MATERIAL DEFORMATION WAS ALSO OBSERVED IN THE AREA WHERE THE ROD CONTACTS THE BENDER ON BOTH ARMS. ON THE LEFT HAND SIDE BENDER: THE DISTAL TIP BROKEN ON ANGULATED ARM SECTION. THE BROKEN PIECE WAS NOT RETURNED FOR EVALUATION. MODERATE MATERIAL DEFORMATION WAS ALSO OBSERVED IN THE AREA WHERE THE ROD CONTACTS THE BENDER ON BOTH ARMS. REVIEW OF THE DEVICE HISTORY RECORD IDENTIFIED THAT THE LOT WAS RELEASED TO STOCK ON 5/7/07 WITH A QUANTITY OF 1 SET; NO DISCREPANCIES WERE NOTED DURING THE RELEASE OF THIS SET. AS SUCH, A REVIEW OF THE DEVICE HISTORY RECORD IDENTIFIED NO ISSUES DURING THE MANUFACTURING AND RELEASE OF THIS PRODUCT THAT COULD HAVE CONTRIBUTED TO THE PROBLEM REPORTED BY THE CUSTOMER. THE PRODUCT WAS RELEASED ACCOMPLISHING ALL QUALITY REQUIREMENTS. A TWELVE MONTH REVIEW OF THE COMPLAINT TREND ANALYSIS FOR THE MODIFIED 5.5 ROD BENDERS FOUND NO EMERGING TRENDS. THE ROOT CAUSE IS UNKNOWN. HOWEVER, THE TWO INSTRUMENTS IN THE SET WERE MOST LIKELY SUBJECTED TO A HIGHER THAN ANTICIPATED STRESS DURING THE AGGRESSIVE BENDING OF THE COBALT CHROME RODS. NO CORRECTIVE ACTION IS REQUIRED AS THERE HAS BEEN NO ISSUE IDENTIFIED IN THE MANUFACTURING OR RELEASE OF THE DEVICE AND THERE HAS BEEN NO OBSERVED SYSTEMIC TREND. THEREFORE, THE COMPLAINT WILL BE CLOSED WITH NO FURTHER ACTION REQUIRED. AS NOTED, BREAKAGE DID NOT OCCUR DURING A SURGICAL PROCEDURE. IF INFORMATION IS OBTAINED THAT WAS NOT AVAILABLE FOR THE INITIAL MEDWATCH, A FOLLOW-UP MEDWATCH WILL BE FILED AS APPROPRIATE.
