Key takeaways:
- Results showed substantial rates of neural axis abnormalities in adolescent idiopathic scoliosis patients undergoing surgery.
- The need for neurosurgical intervention was not substantial.
In this video, Kevin M. Neal, MD, discussed the relationship between rates of neural axis abnormalities in patients with adolescent idiopathic scoliosis and the potential need for neurosurgical intervention.
“Our conclusions are that rates of identification of any neural axis abnormality and Chiari or syrinx malformations in adolescent idiopathic scoliosis patients undergoing surgery was substantial, but the need for actual neurosurgical intervention was low,” Neal said. “Demographic and radiographic factors were not predictive of positive MRI findings, and positive MRI findings were not predictive of intraoperative neuromonitoring changes.”
Neal and colleagues performed a retrospective review using prospectively collected data from 2015 to 2022 on neural axis abnormalities, neurological consultations and neurosurgical interventions in patients with adolescent idiopathic scoliosis.
“Our study provides insight into the rates at which patients with presumed adolescent idiopathic scoliosis requiring surgery have neural axis abnormalities vs. the rate at which these abnormalities require neurosurgical intervention or cause intraoperative neuromonitoring changes,” Neal said. “We think preoperative MRI scans should be considered for patients undergoing surgery for adolescent idiopathic scoliosis.”
