Timing of intraoperative neurophysiological monitoring (IONM) recovery and clinical recovery after termination of pediatric spinal deformity surgery due to loss of IONM signals

i) Study design: multicenter, multidisciplinary, retrospective study of pediatric patients
ii) Most common causes of IONM loss were screw placement (27/66, 40.9%) and rod correction (19/66, 28.8%).
iii) Delayed clinical neurologic recovery (> 72 hours) was significantly associated with unmonitorable IONM signals when returned to the operating room (p=.006)
