Manufacturer Narrative
This follow-up report is being submitted to relay additional information.Complaint sample was evaluated and the reported event was confirmed.The screw was visually evaluated and found to show signs of use.The screw showed significant damage at the cross-drive interface on the head of the screw.Functional testing was done for retention using a driver and blade.The blade was inserted into the driver and the screw, then the assembly was lifted by the screw to verify the cross-drive feature could support the weight of the blade and driver.The screw failed this retention test, therefore, the complaint is confirmed.Device history record (dhr) review was unable to be performed as the lot number of the device involved in the event is unknown.Investigation results concluded that the reported event was due to excessive force being applied beyond what the screw is designed to encounter on the screw head during use.Potential contributing factors are using a worn or incorrect blade and incorrect alignment of the blade and screw.The ifu for this screw (ifu for cranial plating (01-50-1540) revb) states in the section titled 'bone screws': the screwdriver, which has been designed, for a particular system of screws must always be used to be sure that proper screwdriver/screw head connection is achieved.Incorrect alignment or fit of the screwdriver to the screw head may increase the risk of damage to the implant or screwdriver.Excessive torque can cause the screw to fracture.A summary of the investigation has been sent to the complainant.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.
