Additional Manufacturer Narrative

Correction: please refer to section a2 (age at time of event).The reported event could be confirmed, since the device was returned for evaluation and matches the alleged failure.The received drill is broken from the tip and the broken fragment was not returned.Broken surface of the drill appears relatively smooth without showing any plastic deformation signs which indicates towards a brittle failure of the drill due to mechanical overload leading to sudden breakage.Edges of the drill are slightly deformed and worn out which indicates towards the significant usage of the device.The outer diameter of the drill was found within specification.Furthermore, a hardness test according to (b)(6) on the returned item indicates the material being in accordance with the values in the material specification.A review of the device history for the reported lot did not indicate any abnormalities.No corrective actions are required at this time.A review of the labeling did not indicate any abnormalities.No indications of material, manufacturing or design related problems were found during the investigation.Based on the investigation, the root cause was attributed to be user related.The event was caused by a mechanical overload while usage of the drill.Wear marks and deformation indicates that the device was already blunt prior to surgery and a worn-out instrument is more prone to breakage.The hcp might have failed to inspect the instrument properly prior to use, as stated in the ifu.In the provided surgery report, the incident of the drill breakage is mentioned but there is no useful information available to comment upon the further possibilities of failure, other records like x-rays and ct scans could be beneficial to add more observations in the investigation but unfortunately these records are missing.If any additional information is provided, the investigation will be reassessed.
