    DEPUY SYNTHES IS SUBMITTING THIS REPORT PURSUANT TO THE PROVISIONS OF 21 CFR, PART 803. THIS REPORT MAY BE BASED ON INFORMATION WHICH DEPUY SYNTHES HAS NOT BEEN ABLE TO INVESTIGATE OR VERIFY PRIOR TO THE REQUIRED REPORTING DATE. THIS REPORT DOES NOT REFLECT A CONCLUSION BY FDA, DEPUY SYNTHES OR ITS EMPLOYEES THAT THE REPORT CONSTITUTES AN ADMISSION THAT THE DEVICE, DEPUY SYNTHES, OR ITS EMPLOYEES CAUSED OR CONTRIBUTED TO THE POTENTIAL EVENT DESCRIBED IN THIS REPORT. IF THE INFORMATION IS UNKNOWN, NOT AVAILABLE OR DOES NOT APPLY, THE SECTION/FIELD OF THE FORM IS LEFT BLANK. H3, H4, H6: PART # 03.632.036; SYNTHES LOT # H781088; SUPPLIER LOT # H781088; RELEASE TO WAREHOUSE DATE: 18 APR 2019; SUPPLIER: (B)(4); NO NCR'S WERE GENERATED DURING PRODUCTION. REVIEW OF THE DEVICE HISTORY RECORD(S) SHOWED THAT THERE WERE NO ISSUES DURING THE MANUFACTURE OF THIS PRODUCT, AND ANY SUB-COMPONENTS, WHICH WOULD CONTRIBUTE TO THIS COMPLAINT CONDITION. VISUAL INSPECTION: VISUAL INSPECTION OBSERVED THAT THE DISTAL THREADED TIP OF THE RETURNED PART IS PARTIALLY BROKEN WITHOUT SEPARATING INTO 2 OR MORE PIECES. MOREOVER, THE DEVICE IS IN A VERY USED CONDITION. THE OBSERVED DAMAGE IS CONSISTENT WITH THE REPORTED COMPLAINT CONDITION AS SUCH THE COMPLAINT CONDITION CAN BE CONFIRMED. ALL FEATURES RELATED TO THE REPORTED COMPLAINT CONDITION WERE REVIEWED AND NO OTHER ISSUES WERE IDENTIFIED. DIMENSIONAL INSPECTION: A DIMENSIONAL TEST IS NOT APPROPRIATE, SINCE ALL COMPLAINT-RELEVANT DIMENSIONS CAN NO LONGER CORRESPOND TO THE VALID TECHNICAL DRAWINGS SPECIFICATIONS DUE TO THE DAMAGE INCURRED. DOCUMENT/SPECIFICATION REVIEW: THE MANUFACTURING REVIEW SHOWS THAT THE PRODUCTION PROCEDURE WAS ACCORDING TO THE SPECIFICATIONS AND THERE WERE NO ISSUES THAT WOULD CONTRIBUTE TO THIS COMPLAINT CONDITION. SUMMARY: OUR INVESTIGATION HAS SHOWN THAT THE COMPLAINT CONDITION IS CONFIRMED DUE TO THE RECEIVED CONDITION OF THE DEVICE. BECAUSE OF THE DAMAGE, IT IS NOT POSSIBLE TO MEASURE THE RELEVANT DIMENSION. ALTHOUGH NO DEFINITIVE ROOT-CAUSE CAN BE DETERMINED ITS POSSIBLE THE DEVICE ENCOUNTERED UNINTENDED FORCES SUCH AS EXCESSIVE TORQUE WHILE IN USE, WHICH FINALLY RESULTED INTO CRACK AT THE THREADED PART. MOREOVER, ALL DETECTED DAMAGES ARE POTENTIAL END OF LIFE INDICATORS WHICH LET US ALLUDE THAT THIS DEVICE WAS OFTEN AND INTENSIVE USED. THIS END OF LIFE INDICATORS COULD ALSO HAVE HAD CONTRIBUTED TO THE MALFUNCTION OF THE DEVICE. PLEASE FIND INFORMATION FOR END OF LIFE INDICATORS OF REUSABLE INSTRUMENTS. DURING THE INVESTIGATION, NO PRODUCT DESIGN OR MANUFACTURING ISSUES WERE OBSERVED THAT MAY HAVE CONTRIBUTED TO THE COMPLAINT CONDITION. ADDITIONAL MONITORING FOR ANY POTENTIAL SAFETY SIGNALS WILL BE CONDUCTED THROUGH COMPLAINT TRENDING AND OTHER POST MARKET SAFETY SURVEILLANCE ACTIVITIES. BASED ON THE INVESTIGATION FINDINGS, IT HAS BEEN DETERMINED THAT NO CORRECTIVE AND/OR PREVENTATIVE ACTION IS PROPOSED. DEVICE WAS USED FOR TREATMENT, NOT DIAGNOSIS. IF INFORMATION IS OBTAINED THAT WAS NOT AVAILABLE FOR THE INITIAL MEDWATCH, A FOLLOW-UP MEDWATCH WILL BE FILED AS APPROPRIATE.

    Description of Event or Problem · 1

    DEVICE REPORT FROM (B)(6) REPORTS AN EVENT AS FOLLOWS: IT WAS REPORTED THAT ON (B)(6) 2020 DURING A SPONDYLODESIS PROCEDURE TWO INSTRUMENTS BROKE WHEN INSERTING THE IMPLANTS. THE LONG OUTER RETAINING SLEEVE BROKE WHEN INSERTING THE MATRIX POLYAXIAL SCREW. THE THREADED PART WOULD NOT ENGAGE WHOLLY INTO THE HEAD OF THE SCREW AND IT BROKE OFF. ANOTHER RETAINING SLEEVE WAS USED TO FINISH THE INSERTION. THE SCREWDRIVER ALSO BROKE WHEN LOCKING THE END CAPS DESPITE BEING USED WITH THE TORQUE LIMITING ATTACHMENT. THE PART OF THE SCREWDRIVER THAT BROKE OFF HAD TO BE RETRIEVED FROM THE PATIENT. TWO (2) ADDITIONAL HOLDING SLEEVE-LONG FOR MATRIX WERE SUBMITTED AS PART OF THIS COMPLAINT SINCE THE CONDITIONS UNDER WHICH THEY BROKE ARE VERY SIMILAR TO THE EVENTS IN THIS COMPLAINT. CONCOMITANT DEVICES: UNKNOWN MATRIX POLYAXIAL SCREW (PART# UNKNOWN, LOT# UNKNOWN, QUANTITY# 1). UNKNOWN END- CAP (PART# UNKNOWN, LOT# UNKNOWN, QUANTITY# 1). THIS REPORT IS FOR ONE (1) HOLDING SLEEVE-LONG FOR MATRIX. THIS IS REPORT 3 OF 4 FOR (B)(4).
