A comprehensive investigation was immediately initiated on receipt of the complaint.It was reported that the patient heard a squeaking noise in his neck a few months post-op.During the first revision, it was observed that the set screw and nut of the connector were loose.The implants were re-tightened during this revision.During the second revision the implants were removed and the assembly swage of the anchor was compromised so the nut was separated from the rest of the anchor.Most of the damage observed on the anchor and threads is consistent with extrication.There is a significant abrasion on the bottom of the hook portion of the anchor.The abrasions on the rod and on the anchor with lot cyey are consistent with loading from a rod slip.No definitive root cause could be determined.Patient fall likely contributed to the loosening and dislocation of the nuts.The manufacturing and inspection records were reviewed and no discrepancies were found.
