Event Description

Medtronic received information regarding a navigation device being used intra-operatively during a sacroiliac and thoracolumbar procedure.It was reported that a 1st spin was taken and the surgeon was navigating and placing screws but it felt off, took another spin and all the screws were placed medial and inferior.When the site went to take a second spin the imaging system had an error message stating that a problem occurred that will cause inaccuracy.Eventually the site was able to take the spin and it was still inaccurate.Brought in another imaging system and issue was resolved.There was a surgical delay of less than one hour.No known impact to patient outcome.

Event Description

Additional information was received.The inaccuracy amount was approximately 5-10 millimeters medially and inferiorly.The site performed three spins due to the inaccuracy, after the first spin was inaccurate, the site used the same imaging system to do another spine and it was still off so the site did not use that spin for navigation then brought in a different imaging system and spun again with that one and used that spine to navigate and it was accurate.Two unused spins total.The screws were removed then replaced after making new plans off the imaging system spin because the screws were in the wrong location from the original imaging system spin.
