Radiographs were not received.The implants remain in-situ.Revision surgery has not occurred.The reported event was not confirmed and no root cause can be determined at this time, although the significant comorbidities or possible impact/trauma may have contributed to the event.No further investigation can be completed at this time.No patient injury has been reported.Potential adverse events and complications: "potential risk identified with the use of this system, which may require additional surgery, include: bending, fracture or loosening of implant component(s), loss fixation, nonunion or delayed union, fracture of the vertebra, implant subsidence".Warnings, cautions and precautions: "internal fixation appliances are load-sharing devices that hold bony structures in alignment until healing occurs.If healing is delayed, or does not occur, the implant may eventually loosen, bend, or break.Loads on the device produced by load bearing and by the patient's activity level will dictate the longevity of the implant".
