PRODUCT COMPLAINT # (B)(4). THIS REPORT IS BEING SUBMITTED PURSUANT TO THE PROVISIONS OF 21 CFR, PART 803 (AND/OR PART 4, AS APPLICABLE). THIS REPORT MAY BE BASED ON INFORMATION WHICH HAS NOT BEEN INVESTIGATED OR VERIFIED PRIOR TO THE REQUIRED REPORTING DATE. THIS REPORT DOES NOT REFLECT A CONCLUSION BY DEPUY SYNTHES, OR ITS EMPLOYEES THAT THE REPORT CONSTITUTES AN ADMISSION THAT THE PRODUCT, DEPUY SYNTHES, OR ITS EMPLOYEES CAUSED OR CONTRIBUTED TO THE POTENTIAL EVENT DESCRIBED IN THIS REPORT. IF INFORMATION IS OBTAINED THAT WAS NOT AVAILABLE FOR THE INITIAL MEDWATCH, A FOLLOW-UP MEDWATCH WILL BE FILED AS APPROPRIATE. INVESTIGATION SUMMARY THE PRODUCT WAS RETURNED TO DEPUY SYNTHES FOR EVALUATION. THE DEPUY SYNTHES TEAM CONDUCTED A VISUAL INSPECTION OF THE RETURNED DEVICE. VISUAL INSPECTION OF THE RETURNED DEVICE FOUND THAT THE MODULAR BOX OSTEOTOME HAS BENT EDGES. THE DEVICE EXHIBITS AN OVERALL WORN CONDITION CONSISTENT WITH CONSTANT USAGE FOR A LONG PERIOD OF TIME. THIS CONDITION IS CONSISTENT WITH MULTIPLE USES UNDER EXTREME ECCENTRIC LOADING RESULTING IN PREMATURE BENDING, HOWEVER TAKING IN CONSIDERATION THE AGE OF THE DEVICE THE POTENTIAL CAUSE CAN BE ATTRIBUTED TO END OF LIFE. THE LIFECYCLE REQUIREMENTS OF THE DEVICE ARE EVENT RELATED AND DEPEND ON THE USE AND INSPECTION OF THE DEVICE IN CLINICAL PRACTICE. AS THE DEVICE CAN BE DAMAGED ON THE FIRST OR 100TH USE, THE DEVICE MUST BE PROPERLY INSPECTED PRIOR TO EACH SURGICAL USE. REFER TO THE DEVICE/COUNTRY SPECIFIC IFU FOR INFORMATION RELATED TO END OF LIFE, REPROCESSING INSTRUCTIONS, AND INSPECTION PROCEDURES. A DIMENSIONAL INSPECTION WAS NOT PERFORMED SINCE IT WAS NOT APPLICABLE TO THE COMPLAINT CONDITION. A FUNCTIONAL TEST WAS NOT PERFORMED SINCE IT WAS NOT APPLICABLE TO THE COMPLAINT CONDITION. THE OVERALL COMPLAINT WAS CONFIRMED AS THE OBSERVED CONDITION OF THE MODULAR BOX OSTEOTOME WOULD HAVE CONTRIBUTED TO THE COMPLAINED ISSUE. BASED ON THE INVESTIGATION FINDINGS, THE POTENTIAL CAUSE IS TRACED TO END OF LIFE, AND IT HAS BEEN DETERMINED THAT NO CORRECTIVE AND/OR PREVENTATIVE ACTION IS REQUIRED. THERE IS NO INDICATION THAT A DESIGN OR MANUFACTURING ISSUE HAS CAUSED THE REPORTED COMPLAINT CONDITION. AS PART OF DEPUY SYNTHES QUALITY PROCESS, ALL DEVICES ARE MANUFACTURED, INSPECTED, AND RELEASED TO APPROVED SPECIFICATIONS. ADDITIONAL MONITORING FOR ANY POTENTIAL SAFETY SIGNALS WILL BE CONDUCTED THROUGH COMPLAINT TRENDING AND OTHER POST-MARKET SAFETY SURVEILLANCE ACTIVITIES. DEVICE HISTORY THE PRODUCT INVESTIGATION FOUND NO EVIDENCE SUSPECTING AN ERROR IN THE MANUFACTURING OR MATERIAL THAT WOULD BE A CONTRIBUTING FACTOR IN THE REPORTED ALLEGATION(S). A MANUFACTURING RECORDS EVALUATION (MRE) WAS NOT PERFORMED.
