Additional Manufacturer Narrative
Product was not returned to the manufacturer for evaluation.Therefore, we are unable to determine the definitive cause of the reported event.Radiographic image review result: three images provided for l2 corpectomy with anterior instrumentation and l1-l3 posterior stabilization.The first ap x-ray shows the interbody cage translated out of the corpecting defect.The second image shows the endcap not in contact with the l1 interior end plate.The third image shows contact with the end plate.It is probable that the cage chipped and lost contact with the endplates along it to translate laterally.If information is provided in the future, a supplemental report will be issued.
Event or Problem Description
Pre op diagnosis: compression fracture procedure performed: anterior vertebral body replacement and posterior fixation were performed post op, after t3 insertion, compression fracture occurred at l3 due to which the implanted cage sank and backed out.The patient underwent revision surgery in which the fixation range of posterior fixation was changed from 1 above-1 below to 3 above-2 below.Autograft was placed where corpectomy was performed, and then the operation was finished.
