    COMPLAINT SAMPLE WAS EVALUATED AND THE REPORTED EVENT WAS CONFIRMED. THE PRODUCT IDENTITIES WERE CONFIRMED. THE ORIGINAL COMPLAINT REPORTED TWO DRIVERS WITH ONE FIXATION PIN AND ONE BLADE GETTING STUCK INSIDE. HOWEVER, THE TWO DRIVERS WERE RETURNED WITH TWO FIXATION SCREWS STUCK INSIDE. THE 90° CONTRA ANGLE DRIVERS (PART# 24-1189, LOT# 267770, 593680) WERE RETURNED WITH RIBFIX BLU SYSTEM TEMPORARY FIXATION SCREW, CONTRA ANGLE (PART# 76-0017, LOT# 106440, UNK) STUCK INSIDE. THE TWO DRIVERS APPEARED TO BE IN GOOD CONDITION OVERALL. FUNCTIONAL TESTING WAS DONE BY ATTEMPTING TO REMOVE THE SCREWS FROM THE DRIVERS. THE SCREWS COULD NOT BE REMOVED, THEREFORE THE COMPLAINT IS CONFIRMED. THE DRIVERS WERE DISASSEMBLED FOR FURTHER INSPECTION. WHEN THE COVER OF THE HEAD ASSEMBLY WAS REMOVED FROM THE DRIVER (LOT# 593680), IT WAS NOTED THAT THE SCREW (LOT# UNK) HAD ROTATED INSIDE THE DRIVER COLLET AND COULD NOT BE REMOVED WITHOUT BEING ROTATED PRIOR TO PULLING IT OUT. WEAR WAS OBSERVED ON THE MATING SURFACES OF THE SCREW AND THE DRIVER COLLET AND THE LOT NUMBER ON THIS SCREW COULD NOT BE DETERMINED. THE DEVICE HISTORY RECORD (DHR) WAS REVIEWED AND NO DISCREPANCIES WERE FOUND. INVESTIGATION RESULTS CONCLUDED THAT THE REPORTED EVENT WAS DUE TO THAT EXCESSIVE TORQUE WAS APPLIED, BEYOND WHAT IS REQUIRED TO SEAT THE SCREW. THE EXCESSIVE TORQUE WORE DOWN THE SCREW AND COLLET, THEN CAUSED THE COLLET TO ROTATE AROUND THE SCREW. THE INSTRUCTIONS FOR USE (IFU) FOR THESE PRODUCTS STATES IN THE SECTION TITLED 'WARNINGS AND PRECAUTIONS': AVOID UNDUE STRESS OR STRAIN WHEN HANDLING OR CLEANING INSTRUMENTS. THERE ARE NO INDICATIONS OF MANUFACTURING DEFECTS. 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. MULTIPLE MDR REPORTS WERE FILED FOR THIS EVENT, PLEASE SEE ASSOCIATED REPORTS: 0001032347-2018-00572, 0001032347-2018-00573, AND 0001032347-2019-00062
