The exact implant date is unknown but likely (b)(6) or (b)(6) 2023, based on the information obtained.Concomitant products include: reline c handle, torque 26in-lbs.No device was returned as the implant remains in-situ.Radiographs were provided, which were used to confirm the reported event.From the radiographs it can be seen that the two (2) lock screws on the t1 pedicle screw tulips have backed out of proper position.Based on the information obtained the root cause of the reported event is unknown, but may be the result of the associated torque handle used for final tightening not meeting the required torque limiting specification.A follow-up report will be provided if additional information becomes available.Labeling review: ".Care should be taken to insure that all components are ideally fixated prior to closure." ".Patient education: preoperative instructions to the patient are essential.The patient should be made aware of the limitations of the implant and potential risks of the surgery.The patient should be instructed to limit postoperative activity, as this will reduce the risk of bent, broken or loose implant components.The patient must be made aware that implant components may bend, break or loosen even though restrictions in activity are followed." ".Post-operative warnings: during the postoperative phase it is of particular importance that the physician keeps the patient well informed of all procedures and treatments.Damage to the weight-bearing structures can give rise to loosening of the components, dislocation and migration, as well as to other complications." ".Warnings, cautions and precautions: care should be taken to insure that all components are ideally fixated prior to closure.".
