Ten-year Trends of Intraoperative Adverse Events During Scoliosis Surgery: Insights from the British Spine Registry

To quantify the intraoperative adverse events (AEs) during surgical correction of Adolescent Idiopathic Scoliosis (AIS) and adolescent non-idiopathic scoliosis and identify predictors for such events using the British Spine Registry (BSR) dataset. Clinician-reported intraoperative AEs during AIS and non-idiopathic scoliosis procedures were collected from the BSR database. Data included deformity pathways for 10-18-year-olds diagnosed between 2012 and 2023. Intraoperative AEs included excessive bleeding, dural tears, implant malposition, neuromonitoring (IONM) changes, spinal cord injury, and cardiac complications. Hospital Episode Statistics (HES) were monitored to determine the reporting rate. Univariable analysis was utilised to calculate unadjusted Odds ratios (ORs) and 95
