Event Description

Medtronic received information regarding a navigation device being used during a cervical spine procedure.It was reported that during a posterior spinal fusion c3-c5 the site was attempting to do a ct + fluoro registration and noticed an inaccuracy.It was noted the ct was from 7 months ago and in the fluoro shots you could see a significant decrease in disc space causing the anatomy to be different between the ct from 7 months ago and the shots taken for this case.The surgeon checked the accuracy with a pointer before placing screws and noticed it was about 10mm deep and 1 whole vertebral body off.The surgeon attempted an instrument registration with the ct exam and was unable to pass registration and aborted the use of medtronic navigation.There was no impact on patient outcome.
