Event Description

Medtronic received information regarding a guidance system.It was reported that the patient had a questionable scan in which the re presentative recommended to not proceed with the case, however, the surgeon asked that they still try.They proceeded to register and got green values.It was noted they were diligent in scrolling through the level verification and did not notate any shift.Nothing seemed amiss throughout the case.However, when they took the final xray, it was noticed all screws had deviated and were not to plan which caused a tear in the dural.Screws were redirected manually with flouro and navigation was aborted.Additional information received from a manufacturer representative indicated that the procedure performed was a l4-s1 posterior spinal fusion using open solera in which the issue occurred intraoperatively.There was a 45 minute delay to the case as the screws were re-directed under flouro and the patient experienced no negative side effects.The patient was reported to be "fine" and neurologically intact.The amount of deviation was reported to have been between 3.5 and 10 millimeters (mm).
