Manufacturer Narrative

Correction: refer to d4 lot number.The reported event could not be confirmed, since the device was not returned for evaluation and no other evidences were provided.The device inspection was not possible as the product was not returned for investigation.The device history record could not be reviewed because the affected device was not returned, and the correct lot number was not communicated.A review of the labeling did not indicate any abnormalities.The instructions for use instructs user that: ¿when engaging the screw, axial pressure of the screwdriver into the screw head must be adequately applied to ensure that the blade is fully inserted into the screw head.This results in proper axial alignment and full contact between driver and screw, minimizing the risk of damage and leading to optimal friction fit performance.Prior to implant explantation, the screw head recess should be cleaned of debris by means of a scalpel or other instrument to provide an optimal fit between blade and screw.¿ 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.However, one of the probable root causes could be insufficient cleaning of the debris present in screw head recess by means of a scalpel or other instrument to provide an optimal fit between blade and screw.If device is returned or any further information is provided, the investigation report will be reassessed.
