    Additional Manufacturer Narrative · 1

    AN INTERNAL COMPLAINT INVESTIGATION WAS PERFORMED FOR THIS ISSUE. SPECIFICALLY, A HISTORICAL COMPLAINTS REVIEW WAS COMPLETED FOR THE ALLEGED DEFICIENCY "BROKEN ANCHOR BOLTS". THERE HAVE BEEN (B)(4) SIMILAR COMPLAINTS FOR ANCHOR BOLTS BREAKING BETWEEN JANUARY 1, 2017 AND APRIL 18, 2019. A CAPA AND INVESTIGATION REVIEW WAS ALSO CONDUCTED FOR THE ALLEGED DEFICIENCY "ANCHOR BOLT BROKE" AND THERE HAVE BEEN NO CAPAS OR INVESTIGATIONS OPENED FOR THIS ISSUE TO DATE. A BATCH RECORD REVIEW WAS CONDUCTED; (B)(4) LSBK1-AX-06 ANCHOR BOLTS WERE PLANNED FOR THE WORK ORDER AND (B)(4) WERE COMPLETED. NO ISSUES WERE NOTED IN THE WORK ORDER PROCESS NOTES THAT WOULD CONTRIBUTE TO THE REPORTED COMPLAINT AND ALL 50 LSBK1-AX-06 LSBK1-AX-06 ANCHOR BOLTS PASSED THE IN-PROCESS AND FINAL QC CHECKS. ON MAY 8, 2019 AD-TECH RECEIVED ONE ANCHOR BOLT, LSBK1-AX-06 FROM LOT 0121089 208140677, THAT WAS RETURNED IN THE AD-TECH PRODUCT BOX. BOTH SEALS WERE BROKEN AND RE-TAPED. THERE WAS WRITING ON THE OUTSIDE OF THE BOX: "DEI-2019-00146," "2 LE 2512," AND SOME ILLEGIBLE WRITING. INSIDE THE PRODUCT BOX, WAS A SEALED BIOHAZARD BAG WITH AN OPAQUE POUCH AND THE ANCHOR BOLT COULD NOT BE SEEN THROUGH THE PACKAGING. AS THERE WAS NO EVIDENCE THAT A SUCCESSFUL STERILIZATION HAD OCCURRED, THE PRODUCT WAS NOT REMOVED FROM THE PACKAGING. THOUGH THE REPORTED DEFICIENCY COULD NOT BE CONFIRMED THROUGH AN EVALUATION OF THE RETURNED PRODUCT, PICTURES WERE SENT BY THE COMPLAINANT SHOWING THE ANCHOR BOLT IN TWO PIECES. EACH PIECE WAS BENT NEAR THE BREAK, AND THE DISTAL THREADS THAT FIX INTO THE SKULL WERE SEVERELY DAMAGED AS WELL. THIS EXTRANEOUS DAMAGE LIKELY WAS FROM TRYING TO REMOVE THE THREADS AT EXPLANTATION, BUT THAT COULD NOT BE CONFIRMED AT THE TIME OF THE EVALUATION. BECAUSE THERE WERE PICTURES WITH THE ANCHOR BOLT BROKEN INTO TWO PIECES, THE REPORTED DEFICIENCY WAS CONFIRMED. THE RISK LEVEL FOR THIS ISSUE REMAINS ALAP (AS LOW AS POSSIBLE). ADDITIONALLY, BASED ON A REVIEW OF PREVIOUS COMPLAINTS FOR ANCHOR BOLT BREAKAGES AND AN ANALYSIS OF ALL ANCHOR BOLT BREAKAGE COMPLAINT DATA, THE CURRENT RATE OF ANCHOR BOLT BREAKAGE COMPLAINTS VERSUS PRODUCTS SOLD IS VERY LOW; (B)(4) OVER THE PAST 2 YEARS. AD-TECH IS CONTINUING TO MONITOR THIS ISSUE CLOSELY.
