The Use of Intraoperative Neuromonitoring in Lateral Lumbar Interbody Fusion Surgery

This study found that changes in IONM were rare (0.50%). In the case of the one true positive, this occurred during repositioning, and the IONM change was not successful as a preventative measure. These results indicate that the use of SSEPs may not be supported for the LLIF approach. While medico-legal concerns promote its usage, the low rates of neurologic deficits and costs associated with IONM should be considered, leading to a reexamination of its use in LLIF spinal surgery.
