Event Description
|
Medtronic received information regarding a guidance system being used during a spinal procedure.It was reported that there were deviations during a l4-l5 stage 2 ap surgery post alif.The surgical system was mounted to the patient using a schanz pin placed in the left psis connected to a bone mount bridge.The surgeon started at l4 and then moved to l5 when placing screws.Navigation and drill were used during the procedure.The manufacturer representative was not sure if navigation accuracy was checked during the procedure.An accuracy check was not completed prior to the procedure.The l5 screws were deviated to a more cephalad position by 3.5 to 5 mm.The screw violated an adjacent endplate.The lateral to medial screws were on trajectory.The c-arm was used to confirm the placement of the screws during the procedure and that was when the deviation was found.An o-arm spin was done to confirm placement.There were no issues with the guidance system during the procedure.The cause of the deviation was not determined.The screws were repositioned during the procedure using flouro.There was no patient harm intra-op and post-op.Neuromonitoring was used and the screws tested safe.There was no patient harm and the procedure was delayed less than an hour.
