Intraoperative neuromonitoring and mapping during spinal cord untethering surgery. Preliminary findings from a single-centre paediatric neurosurgery unit.

Objective To review intraoperative neuromonitoring (IONM) and mapping (IONMa) utility during paediatric tethered cord surgery with particular attention to feasibility, measures to prevent injury, and postoperative outcome. Methods A retrospective analysis of spinal cord untethering surgery between 2015-2022. Cohort demographics, clinical and imaging characteristics of tethered cord, IONM/IONMa data and procedural details were summarised and associations between variables explored. Clinical outcome was assessed 3-months post procedure via review of medical records.
