Intraoperative Neurophysiological Monitoring for Minimally Invasive 1- and 2-Level Transforaminal Lumbar Interbody Fusion: Does It Improve Patient Outcome?

Time, cost, length of stay, and postoperative complication rates in monitored versus unmonitored patients. A: The average surgery time for patients receiving intraoperative monitoring (IOM) was significantly higher than the surgery time for patients who were not monitored (No IOM) (P=0.009). B: The total average hospital cost for patients receiving IOM was significantly higher than the cost for patients who did not receive IOM (P=0.008). C: The average length of hospital stay was comparable in the 2 groups (P=0.8). D: The percentage of patients requiring revisions for surgical malposition (P=0.93) was not statistically significant between the 2 groups.
