This report is being resubmitted for an incident that occurred earlier.The locking caps were returned for evaluation and found to pass all dimensional and functional inspections.Two creo fenesfrated mis locking caps show wear marks on the base of the implant which is consistent with rubbing between the rod and the base of the set screw during proper final tightening.One creo mis locking cap showed no wear pattern near the center, the lack of an hour glass pattern on this surface indicates the locking cap partially engaged the rod as the locking cap was tightened.Partial engagement of the locking cap could be caused by the rod or screw head being tilted at such an angle that the bottom of the locking cap does not contact the rod.This could be cause by additional tissue preventing the complete seating of the rod in the screw head.However, the exact cause of the reported issue could not be determined.The following sections have been updated for this supplemental report: b4, e1, h2, h6, h10.
