Additional Manufacturer Narrative

H3, H6: THE DEVICE WAS NOT RETURNED FOR EVALUATION. HOWEVER, THE PHOTOGRAPHS WERE REVIEWED, AND REVEALED THAT PART OF THE THREADED TIP IS FRACTURED. 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 BASED ON THE HISTORICAL DATA REVEALED A SIMILAR EVENT FOR THE LISTED BATCH, 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 THIS EVENT WAS PREVIOUSLY IDENTIFIED AND IT WAS ADDRESSED THROUGH DESIGN CHANGE EVALUATIONS. THE BATCH NUMBER UNDER THIS COMPLAINT WAS MANUFACTURED BEFORE THESE ACTIONS WERE INITIATED. 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 THE DEVICE OR 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.
