    (B)(4). THIS FOLLOW-UP REPORT IS BEING SUBMITTED TO RELAY ADDITIONAL INFORMATION. REVIEW OF THE DEVICE HISTORY RECORDS IDENTIFIED NO DEVIATIONS OR ANOMALIES DURING MANUFACTURING THAT COULD BE RELATED TO THE REPORTED EVENT. BASED ON THE INVESTIGATION IT COULD BE ASSUMED THAT FURTHER POSSIBLE CONTRIBUTING FACTORS TO THE MIGRATION OF THE SCREW MIGHT BE MULTIFACTORIAL RELATED TO EITHER PATIENT CONDITION, BEHAVIOR OR IMPLANTATION PROCEDURE. IF AND TO WHAT EXTENT ANY OF THESE ASPECTS MAY HAVE INFLUENCED THE MIGRATION OF THE SCREW REMAINS UNKNOWN. A DEEPER INVESTIGATION WAS PERFORMED WHICH IDENTIFIED THE DESIGN LIMITATION OF THE CORELOCK MECHANISM AS A POTENTIAL CONTRIBUTING FACTOR AS WELL. HOWEVER, FURTHER BIOMECHANICAL TESTING WAS CARRIED OUT AND AS THE PRODUCT PERFORMANCE IS IN AN ACCEPTABLE RANGE IN COMPARISON WITH LEGALLY MARKETED SIMILAR DEVICES, NO DESIGN CHANGES WERE CONDUCTED. IN CONCLUSION, AS THE CAUSE MAY BE MULTIFACTORIAL AN EXACT ROOT CAUSE COULD NOT BE IDENTIFIED FOR THE MIGRATION OF THE SCREW. IF ANY FURTHER INFORMATION IS FOUND WHICH WOULD CHANGE OR ALTER ANY CONCLUSIONS OR INFORMATION, A SUPPLEMENTAL WILL BE FILED ACCORDINGLY. ZIMMER BIOMET WILL CONTINUE TO MONITOR FOR TRENDS.
