Additional Manufacturer Narrative

THE ASSOCIATED DEVICE WAS RETURNED AND EVALUATED. THE VISUAL INSPECTION REVEALED THAT THE PROXIMAL JOINT OF THE INTERNAL SHAFT FRACTURED WITH MATERIAL MISSING. THE OUTER HANDLE IS INTACT AND WAS RETURNED, THE ENTIRE DEVICE IS WORN FROM USE. A REVIEW OF THE PRODUCTION ORDER DID NOT REVEAL A MANUFACTURING ABNORMALITY THAT COULD HAVE CAUSED OR CONTRIBUTED TO THE REPORTED INCIDENT. A REVIEW OF COMPLAINT HISTORY REVEALED SIMILAR EVENTS FOR THE LISTED PART NUMBER OVER THE PREVIOUS 12 MONTHS, BUT NO SIMILAR EVENTS FOR THE BATCH BASED ON THE HISTORICAL DATA, THIS FAILURE MODE WILL BE MONITORED FOR FUTURE COMPLAINTS FOR ANY NECESSARY CORRECTIVE ACTIONS. A REVIEW OF THE RISK MANAGEMENT FILE REVEALED THIS FAILURE MODE WAS PREVIOUSLY IDENTIFIED. THE ANTICIPATED RISK LEVEL IS STILL ADEQUATE. A HISTORICAL REVIEW CONCLUDED THAT A SIMILAR EVENT WAS PREVIOUSLY IDENTIFIED, AND ESCALATED ACTIONS WERE PERFORMED. IT HAS BEEN CONCLUDED THAT THERE IS A POTENTIAL FOR BREAKAGE IF USED AFTER THE EXPECTED LIFETIME OR EXCESSIVE FORCE IS USED AS THIS DEVICE IS A REUSABLE INSTRUMENT AND IT IS EXPECTED TO WEAR OVER TIME. ALSO, THE FAILURE RATE OF THIS ISSUE IS WITHIN EXPECTED AND DOCUMENTED IN THE RISK FILE. AT THIS TIME, WE HAVE NO EVIDENCE TO CONCLUDE THAT THE PRODUCT FAILED TO MEET ANY SPECIFICATIONS AT THE TIME OF MANUFACTURE. THIS DEVICE IS A REUSABLE INSTRUMENT THAT CAN BE EXPOSED TO NUMEROUS SURGERIES. DAMAGE FROM PROLONGED USE, MISUSE OR ROUGH HANDLING ARE LIKELY POTENTIAL FACTORS THAT COULD CONTRIBUTE TO THE REPORTED EVENT. WE RECOMMEND THAT ALL REUSABLE INSTRUMENTS BE ROUTINELY INSPECTED FOR WEAR AND DAMAGE AND REPLACED AS NECESSARY. BASED ON THIS INVESTIGATION, THE NEED FOR CORRECTIVE ACTION IS NOT INDICATED. SHOULD ADDITIONAL INFORMATION BE RECEIVED, THE COMPLAINT WILL BE REOPENED. NO FURTHER INVESTIGATION IS WARRANTED FOR THIS COMPLAINT; HOWEVER, WE WILL CONTINUE TO MONITOR FOR FUTURE COMPLAINTS AND INVESTIGATE AS NECESSARY. WE CONSIDER THIS INVESTIGATION CLOSED.
