This report is being resubmitted for an incident that occurred earlier.The device was not returned for evaluation as it was discarded by the hospital.Inspection of the imaging provided confirmed the failed fusions and shows the screw pullout from the left pedicle at t12, left pedicle at l1, and left pedicle at s1.It's possible that poor bone quality due to recurring epidural abscesses and infection contributed to the screws pulling out of the pedicles.Additionally, excessive force placed on the implant during unknown patient loading, incorrect implant selection, or incorrect screw placement could have contributed.However, the exact cause of the reported issue could not be determined.
