Manufacturer Narrative

The reported event could not be confirmed, since the device was not returned for evaluation and no other evidences were provided.Additional information reported that: after drilling and before inserting the screw, drilling into the next screw hole was made and then inserting the screw.This caused the plate to shift and the drill hole to be shifted from the initial position, which seemed to have caused locking failure.Based on investigation, the root cause was attributed to a user related issue.The failure was caused by misalignment of the implant before screw insertion.More detailed information about the complaint event as well as the affected device must be available in order to determine the root cause of the complaint event.If the device is returned or if any additional information is provided, the investigation will be reassessed.Device discarded.
