Additional Manufacturer Narrative
This follow-up report is being submitted to relay additional information.The complaint is confirmed.The qty two 1.5x4mm x-drive tf sd screw ea (part# 91-6704, lot# unk) were returned for investigation.A visual inspection was conducted.The screw tips show signs of wear.Functional testing was completed by attempting to insert the screws into a piece of white oak wood using a 01-7390 driver handle lot 048760 with a 15-1196 1.5mm bit lot number 406650.When an attempt was made to turn the screws into the wood the screw tips were unable to penetrate the wood surface.The dhr will not be reviewed as the lot number remains unknown.There are no indications of manufacturing defects.For this part (91-6704) and the previous one year (from the notification date) the screw not inserting into bone, there is a complaint rate of 0.003% which is no greater than the occurrence listed in the application fmea.The most likely underlying cause of the complaint is excessive force applied during an insertion attempt, beyond what the implant is designed to encounter.If any further information is found which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.
