Event Description

Medtronic received information regarding a guidance system being used during a spinal procedure.It was reported that during an open, spinal fusion extension to l3 with previous hardware (l4-s1), the surgeon was having issues with navigation.The surgeon had the camera raised higher for better line of site during the procedure.The surgeon was using long tools and for the first part of the case the surgeon implanted an xlif cage.After the cage was implanted, the surgeon worked from left to right to place screws.During the case, the surgical system had shifted which required the patient to be re-registered.A new snapshot was not taken and navigation was found to be inferior with the navlock tracker.The divot on the system and the anatomy was checked with a passive planar probe, but the inaccurate tracker was not checked.The drill was found to be accurate, but when using the tracker was still inaccurate.Rotating the tracker away from the camera increased accuracy, but showing the spheres directly towards the camera introduced more inac curacies.Removing all lights from the room did not resolve the issue.There was no patient harm and the procedure was delayed less than an hour.The camera and instruments were replaced after the procedure an mineral oil was not going to be use.These actions resolved the issue.
