    Additional Manufacturer Narrative · 1

    DEVICE WAS USED FOR TREATMENT, NOT DIAGNOSIS. A PRODUCT DEVELOPMENT INVESTIGATION WAS PERFORMED FOR THE COUPLING SCREW (PART NUMBER 338.345, LOT NUMBER 5101250). THE SUBJECT DEVICE WAS RETURNED WITH THE COMPLAINT CONDITION STATING DISTAL THREADED TIP HAS SHEARED OFF MID-THREAD AND WAS NOT RETURNED FOR EVALUATION. ONLY 1-2 PARTIAL THREADFORMS REMAIN ON THE RETURNED DEVICE. THE COMPLAINT IS CONFIRMED. THE LENGTH OF THE REMAINING SHAFT PORTION OF THE RETURNED DEVICE MEASURES APPROXIMATELY 193.0 MM. THEREFORE, THE SHEARED OFF TIP FRAGMENT WOULD BE APPROXIMATELY 6MM IN LENGTH WITH REFERENCE TO LENGTH SPECIFICATION OF 298.8 - 299.2MM PER PRODUCT DRAWING. THE INSIDE DIAMETER NEAREST THE BREAK MEASURED 2.61MM WHICH IS WITHIN SPECIFICATION OF 2.58MM - 2.65MM PER PRODUCT DRAWING. AN ACCURATE MEASUREMENT OF THE OUTSIDE MINOR THREAD DIAMETER COULD NOT BE OBTAINED DURING THIS INVESTIGATION DUE TO THE DAMAGE. WHETHER THIS COMPLAINT CAN BE REPLICATED AT CUSTOMER QUALITY (CQ) IS NOT APPLICABLE FOR THIS COMPLAINT CONDITION AS THE RETURNED DEVICE IS ALREADY BROKEN. A VISUAL INSPECTION UNDER 5X MAGNIFICATION, DEVICE HISTORY RECORD (DHR) REVIEW AND DRAWING REVIEW WERE PERFORMED AS PART OF THIS INVESTIGATION. NO PRODUCT DESIGN ISSUES OR DISCREPANCIES WERE OBSERVED. NO NON-CONFORMANCE RECORDS (NCRS) WERE GENERATED DURING PRODUCTION. REVIEW OF THE DEVICE HISTORY RECORD(S) SHOWED THAT THERE WERE NO ISSUES DURING THE MANUFACTURE OF THE PRODUCT THAT WOULD CONTRIBUTE TO THIS COMPLAINT CONDITION. A ROOT CAUSE WAS NOT ABLE TO BE DETERMINED. THE MOST PROBABLE CAUSE IS LIKELY DO TO APPLICATION OF EXCESSIVE OFF-AXIS FORCE RESULTING IN THE TIP TO SHEAR OFF AS IT IS THE LOCATION OF LEAST MATIERIAL CROSS SECTION FOR THE DEVICE. IF INFORMATION IS OBTAINED THAT WAS NOT AVAILABLE FOR THE INITIAL MEDWATCH, A FOLLOW-UP MEDWATCH WILL BE FILED AS APPROPRIATE.
