    THIS FOLLOW-UP REPORT IS BEING SUBMITTED TO RELAY ADDITIONAL AND/OR CORRECTED INFORMATION. AS NO PRODUCT WAS RETURNED, VISUAL AND DIMENSIONAL EVALUATIONS COULD NOT BE PERFORMED. DEVICES ARE USED FOR TREATMENT. NO SURGICAL REPORT IS AVAILABLE FOR INVESTIGATION. THERE IS ONE UNDATED X-RAY PICTURE AVAILABLE. THE PICTURE DEMONSTRATES BACKING OUT OF THE PROXIMAL FIXATION SCREWS. 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, BEHAVIOUR OR IMPLANTATION PROCEDURE. IF AND TO WHAT EXTENT ANY OF THESE ASPECTS MAY HAVE INFLUENCED THE MIGRATION OF THE SCREW REMAINS UNKNOWN. THE INVESTIGATION ALSO CONSIDERED WHETHER THE DESIGN LIMITATION OF THE CORELOCK MECHANISM COULD BE A POTENTIAL CONTRIBUTING FACTOR. HOWEVER, FURTHER BIOMECHANICAL TESTING IDENTIFIED THAT THE PRODUCT PERFORMANCE IS IN AN ACCEPTABLE RANGE IN COMPARISON WITH LEGALLY MARKETED SIMILAR DEVICES. 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 REPORT WILL BE FILED ACCORDINGLY. ZIMMER BIOMET WILL CONTINUE TO MONITOR FOR TRENDS.
