It was reported that there was an issue with s4 set screw. According to the customer report: unable to tighten setscrew using a screwdriver fw732r. While final tightening the setscrew, the surgeon tightened the screwdriver, however the driver kept rotating even after 10n/m was obtained. At the torque value of 10n/m, the torque should have come off in order to avoid excessive torque, however, the screwdriver kept on rotating and the setscrew and the polyaxial screw tab were broken due to over-tightening. The screw and the setscrew were replaced with a new one, however, the surgeon suspected failure of the screwdriver torque wrench ne160r. So he manually final tightened the setscrew without a torque handle, meaning that torque value of 10n/m is not assured. The surgeon was concerned about post-operative loosening of the screw. There was no patient harm. The surgery time was extended over 30 minutes. Patient information was not provided or was not available. The adverse event/malfunction is filed under (b)(4). Associated medwatch-reports: 9610612-2019-00979 ((b)(4) vne160r), 9610612-2019-00993 ((b)(4) sw790t), 9610612-2019-00994 ((b)(4) sw790t), 9610612-2019-00996 ((b)(4) sw790t).
