Additional Manufacturer Narrative
The complainant provided photos of the reported instrument malfunction, which showed a system screw stuck to the distal threads of a system screwdriver.Most of the thread detail of the system screwdriver was fractured and stuck in the cup of the system screw, with less than an entire thread present at the distal tip of the screwdriver.A visual assessment of the returned system screwdriver showed an instrument with repeated use, as identified by surface scratches, handle interface wear marks, and worn laser markings.A physical assessment could not be performed due to the damaged condition of the returned system screwdriver, which would not function as intended and was removed from distributable inventory.A dhr review was performed for the returned complaint device lot and there were no manufacturing anomalies identified.The device met all required specification prior to being released to distributable inventory.This lot has been available for distribution since 2/18/2016.It may be possible to fracture the thread detail of a system screwdriver if the ratcheting screwdriver handle attached to the screwdriver was not in the correct position for screw placement and screw disengagement.The system surgical technique guide provides guidance on appropriate screwdriver and screw engagement and disengagement.Step 5: screwdriver/screw assembly includes the following cautionary statements to reduce the possibility of an instrument malfunction.Cautionary statements from the surgical technique guide: warning - if the ratcheting screwdriver handle (attached to the proximal end of the pedicle screwdriver at this step in the technique) is not placed in the neutral, non-ratcheting position for screw disengagement, the (pedicle screw) driver may be difficult to disengage from the screw.Note: 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.The root cause of this complaint cannot be reliably determined.The complaint investigation suggests the possibility that the ratcheting screwdriver handle attached to the system screwdriver was not in the correct ratcheting position for screw engagement and disengagement.
