H11 ADDITIONAL NARRATIVE: H3, H4, H6: THE PRODUCT WAS RETURNED TO J&J MEDTECH ORTHOPAEDICS FOR EVALUATION. VISUAL INSPECTION OF THE RETURNED DEVICE REVEALED THAT THE SPINDLE NUT SHOWED SLIGHT SIGNS OF DAMAGE OF STRIPPED ON THE INTERNAL THREAD. THIS CONDITION COULD HAVE BEEN CAUSED BY INTERACTION WITH THE MATING DEVICE, WHICH HAS DAMAGE IN THE THREADED AREA, PREVENTING IT FROM BEING FULLY THREADED. THEREFORE, THE REPORTED CONDITION CAN BE CONFIRMED. 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 WAS NOT PERFORMED AS IT IS NOT APPLICABLE TO THE COMPLAINT CONDITION. A FUNCTIONAL EVALUATION WAS PERFORMED USING THE NUT AND THE MATING DEVICE, WHICH THREADED CORRECTLY INITIALLY, HOWEVER, UPON REACHING THE MIDDLE OF THE DEVICE, IT GOT STUCK AND COULD NOT THREAD FURTHER, PRECISELY IN THE AREA WHERE THE THREAD IS DAMAGED. THEREFORE, THE REPORTED CONDITION COULD BE REPLICATED. THE OVERALL COMPLAINT WAS CONFIRMED AS THE OBSERVED CONDITION OF THE SPINDLE NUT 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 J&J MEDTECH ORTHOPAEDICS 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.
