Additional Manufacturer Narrative
A visual assessment of the returned complaint system screwdriver showed an instrument with repeated use, as identified by surface scratches and staining.The tin coating at the distal end of the returned complaint instrument was identified as worn.The square thread detail on the returned system screwdriver was fractured from the screwdriver sleeve and the distal hex tip of the screwdriver was slightly rounded.A functionality assessment was not performed due to the damaged condition of the system screwdriver, which was removed from distributable inventory.A dhr review was performed for the screwdriver complaint lot and there were no manufacturing anomalies identified.The device lot met all required specifications prior to being released to distributable inventory.This lot has been available for distribution since 7/01/2016.It may be possible for the square thread detail of a system screwdriver to fracture if excessive rotational force was applied to the sleeve of the screwdriver or if the attached handle was not in the neutral position when rotated.The sleeve of the screwdriver is tightened into the cup of the system screw to secure it to the driver and prevent toggle.If the sleeve was rotated beyond what is required to secure the screw, it may fracture the square thread detail as observed.There is a cautionary note included in the surgical technique guide that states, "if the user turns the driver with high torque force without placing the handle in the neutral position, this could cause considerable damage to the threads including causing them to break off completely." there have not been any other complaints of similar nature for this device in the past 12 months.The manufacturer will continue to monitor this device for complaints from the field.
