Results of investigation: the device, used in treatment, was returned for evaluation.The clinical/medical team concluded, per complaint details, upon completion of the ps box preparation and while removing the preparation guide the screw in the thumbscrew broke.Reportedly, however, the procedure was completed with the same device without delay and all pieces were recovered.It was communicated that the operative notes were not available for inclusion in the medical investigation.Patient impact beyond the reported event would not be anticipated as the box prep was reportedly already complete, all pieces were recovered, and the patient is reportedly well.No further medical assessment is warranted at this time.A visual inspection confirmed the screw is broken on the gii prim p/s collet w/thmbscrw.The device shows significant signs of wear/usage.A review of the manufacturing records did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.At this time, we have no reason to suspect that the products failed to meet any product specifications at the time of manufacture.A review of complaint history for the listed part revealed no prior complaints for the listed batch.A review of the risk management file revealed this failure mode was previously identified.Damage from prolonged use, misuse or rough handling are likely probable causes of the reported event.We recommend that all reusable instruments be routinely inspected for wear and damage and replaced as necessary.This is a reusable instrument that can be exposed to numerous surgeries; damage from repeated use can occur.Based on this investigation, the need for corrective action is not indicated.Should additional information be received, the complaint will be reopened.No further investigation warranted for this complaint; however we will continue to monitor for future complaints and investigate as necessary.We consider this investigation closed.
