Analysis of 5317 Consecutive Pediatric Spinal Deformity Intraoperative Neuromonitoring (IONM) Alerts

IONM alerts occurred in 4.2% of cases, most frequently at correction/following correction. Corrective actions, most commonly correction of hypotension, theoretically reduced spinal cord dysfunction from 4.2% intraoperatively, to 0.5% (29/5,312) at wake-up and 0.15% (8/5,312) at final exam. This largest single-center experience with IONM in pediatric spinal deformity surgery supports the use of a multimodal IONM, systematic alert response protocol and allows for better preoperative shared-decision making.
