Event Description

Medtronic received information regarding a guidance system being used during a spinal procedure.It was reported that the site aborted the use of the guidacne system during the case.The case was a single level percutaneous case to follow single level olif.At first they had difficulty registering and segmentation was off.They eventually got green values on the levels they were working on but when they sent the arm it l5-left went in the wrong direction.The path of the screw was at a completely incorrect angle.The path seemed to be vertically mirrored to the plan.They did not drill or place a screw.They did not complete an accuracy test as the surgeon decided to abort use of the guidacne system and to continue the case manually.No confirmation of the issue was completed.The issue extended the surgical time by less 1 hour.There was no impact on the patient outcome.

Manufacturer Narrative
