Additional Manufacturer Narrative

PRODUCT COMPLAINT #(B)(4). INVESTIGATION SUMMARY: ACCORDING TO THE INFORMATION RECEIVED, ¿IT WAS REPORTED THAT CHISEL BROKE DURING SURGERY. NO ADVERSE PATIENT EVENT, ALL PIECES WERE RETRIEVED. NO DELAY, NO FURTHER INFORMATION WAS AVAILABLE¿. THE PRODUCT RETURNED TO DEPUY SYNTHES FOR EVALUATION. THE DEPUY SYNTHES TEAM CONDUCTED A VISUAL INSPECTION OF THE RETURNED DEVICE. VISUAL ANALYSIS REVEALED THAT THE DISTAL PORTION OF THE CHISEL WAS BROKEN OFF; FRAGMENT WAS RETURNED FOR EVALUATION. ADDITIONALLY, THE SIGMA HP UNI ANTERIOR CHISEL EXHIBITS AN OVERALL WORN APPEARANCE CONSISTENT WITH NORMAL AND CONSTANT USAGE FOR AROUND 17 YEARS. THE OBSERVED CONDITION WAS IDENTIFIED AS AN END OF LIFE INDICATOR; DAMAGE CONSISTENT WITH REPEATED USE AND SERVICING. 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 AND FUNCTIONAL TESTING WERE NOT PERFORMED AS IT IS NOT APPLICABLE TO THE COMPLAINT CONDITION. THE OVERALL COMPLAINT WAS CONFIRMED AS THE OBSERVED CONDITION OF THE SIGMA HP UNI ANTERIOR CHISEL WOULD CONTRIBUTE TO THE COMPLAINED DEVICE 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 LOT: A DEVICE HISTORY RECORD (DHR) REVIEW OR MANUFACTURING RECORDS EVALUATION (MRE) WAS NOT POSSIBLE BECAUSE THE DATE CODE (PG0408) PROVIDED IS NOT A VALID FINISHED GOODS LOT#. CORRECTED: H3.
