    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. INITIAL REPORTER IS A J&J SALES REPRESENTATIVE. PART # 03.043.028. LOT # 21639401. MANUFACTURING SITE: WERK SELZACH LOGISTIK. RELEASE TO WAREHOUSE DATE: 23 AUG 2021. SUPPLIER: BÄCHLER FEINTECH AG. EXPIRATION DATE: N/A. A MANUFACTURING RECORD EVALUATION WAS PERFORMED FOR THE FINISHED ARTICLE LOT AND NO NON-CONFORMANCES WERE IDENTIFIED. THE PRODUCT WAS RETURNED TO DEPUY SYNTHES AND SENT TO R&D FOR EVALUATION. THE R&D TEAM CONDUCTED A VISUAL INSPECTION OF THE RETURNED DEVICE. VISUAL ANALYSIS OF THE RETURNED SAMPLE WAS PERFORMED ON DRIVING CAP. IT WAS REPORTED THAT THE CROSS PIN CONNECTING THE PULL BUTTON TO THE DRIVING CAP ASSEMBLY GOT LOOSE AND THE DRIVING CAP DISASSEMBLED. RETURNED PART WAS ASSESSED BY R&D AND SENT TO MATERIALS AND TESTING. SINCE THE CROSS PIN THROUGH THE PULL BUTTON WAS NOT RETURNED THE WELD AT THE TIP OF THE PART WHICH IS MANUFACTURED BY THE SAME VENDOR WAS ASSESSED. MATERIALS AND TESTING PROVIDED DRAFTED REPORT THAT SHOWED SOME DEFICIENCIES IN THE WELD. CONCLUSION FROM R&D WAS THAT ALTHOUGH THE WELD MIGHT NOT BE PERFECT THERE MUST BE SOME SIGNIFICANT LOAD LEADING TO THE FAILURE OF THE WELD. MATERIALS AND TESTING SUBSEQUENTLY PERFORMED A FINITE ELEMENT ANALYSIS TO INVESTIGATE ORIGIN OF STRESS AT THE INTERFACE BETWEEN CROSS PIN AND PULL BUTTON. ANALYSIS SHOWED THAT STRONG OFF AXIS HAMMER BLOWS CAN LEAD TO OSCILLATIONS IN THE SYSTEM THAT CAN CAUSE STRESS THAT CAN LEAD TO BREAKAGE OF THE LASER WELD AT THE END OF THE PIN AND SUBSEQUENT MIGRATION. SURGICAL TECHNIQUE GUIDE MENTIONS ¿APPLY LIGHT AND CONTROLLED HAMMER BLOWS TO SEAT THE NAIL¿ AND ¿THE HAMMER GUIDE MAY AID IN CONTROLLING THE DIRECTION OF THE HAMMER BLOWS. THEREFORE, THE HAMMER GUIDE CAN BE ATTACHED TO THE BACK END OF THE DRIVING CAP BY SCREWING BOTH PARTS TOGETHER¿. THE DIMENSIONAL INSPECTION WAS NOT PERFORMED DUE TO POST-MANUFACTURING DAMAGE. AS PART OF DEPUY SYNTHES QUALITY PROCESS, ALL DEVICES ARE MANUFACTURED, INSPECTED, AND RELEASED TO APPROVED SPECIFICATIONS. THE OVERALL COMPLAINT WAS CONFIRMED FOR THE DRIVING CAP. BASED ON THE TESTING PERFORMED BY MATERIALS AND TESTING, THE ROOT CAUSE CAN BE DETERMINED TO BE TRACED TO THE USER. BASED ON THE INVESTIGATION FINDINGS, IT HAS BEEN DETERMINED THAT NO CORRECTIVE AND/OR PREVENTATIVE ACTION IS PROPOSED. ADDITIONAL MONITORING FOR ANY POTENTIAL SAFETY SIGNALS WILL BE CONDUCTED THROUGH COMPLAINT TRENDING AND OTHER POST-MARKET SAFETY SURVEILLANCE ACTIVITIES. DRAWING/SPECIFICATIONS REVIEWED: REV G CURRENT AND MANUFACTURED DIMENSIONAL INSPECTION: N/A 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.
