Event Description

Device report from depuy spine reports an event in (b)(6) as follows: it was reported that in the course of the treatment of a scoliosis, problems occurred during the placement of a pedicle screw with a locking screw.After successful implantation of various pedicle screws, the rod was placed.For this purpose, a rod was cut to size, pre-bent accordingly, inserted into the screw heads and temporarily fixed with end caps (partly single, partly dual).Finally, the caps were tightened with torque.It was noticed that on one screw in a segment that was distracted and compressed, the dual innie did not release the required torque.In the correct sequence, the outer part of the closure cap was first tightened with torque.When the inner portion was subsequently attempted to be tightened, no torque could be released.Instead, the inner part spun in the outer part of the dual-innie.Another dual innie was then used, unfortunately with the same result.A subsequent single innie also did not produce the desired result, this one spinning in the screw head before the torque was triggered.It can therefore assumed that the problem is related to the thread of the screw head.Unfortunately, the lot number of this screw was not readable in situ.At this point, all reduction maneuvers had already been carried out and the rod had been fixed in large part, so changing the screw was no longer an option for the user at this point of the operation.Since, according to the user, there was sufficient stability in the construct, it was decided to leave the screw in place and complete the procedure.The surgery was delayed for fifteen (15) minutes due to the reported event.The procedure was successfully completed.This report is for an unknown locking/set screws.This is report 3 of 3 for complaint (b)(4).
