Event Description
|
Medtronic received information regarding a navigation system.It was reported that after discs dissection of the l3 and 4 under the navigation, free running electromyogram (emg) began to appear during the monitoring when the trial 8*45 was inserted, and both "mep" and "sep" began to fall, so it was changed to perform posterior lumbar interbody fusion (plif) from the posterior side instead of the anterior side.It was reported that paralysis of both lower limbs was caused by trial insertion with concave side invasion, and the postoperative condition was unknown on the day, so when confirmed at the time of this report, report of paralysis was received.There was a reported delay to the procedure of less than one hour.

Event Description

Additional information was received.It was reported that no inaccuracy was observed, ergo the paralysis was unrelated to an inaccuracy.It was reported that the issue occurred during an adult spinal deformity (asd) oblique lumbar interbody fusion (olif) of l2-l5.It was noted that the procedure was changed to be a posterior lumbar interbody fusion (plif) following monitoring results of free-run electromyography, motor-evoked potential (mep) and somatosenrory-evoked potential (sep) during the olif.Additionally it was noted that the concave side of the deformity was approached due to the patient's size.While conducting the procedure, the l3 and l4 intervertebral discs dissection was conducted from the side of the deformity.When the trial was inserted, the free-run electromyography began to show a change in its waveforms.Deterioration in the sep and mep were also observed.The surgeon then opted to discontinue inserting the cage from the oblique lateral.Following this, the cage was installed from the posterior side.Post-operative condition was unknown.
