- Study evaluates clinical and radiological characteristics across intramedullary increased signal intensity (ISI) grades in thoracic ossification of the ligamentum flavum (T-OLF).
- Higher ISI grades correlate with worse preoperative neurological status, greater spinal canal compression, complex OLF morphology, and increased intraoperative blood loss.
- High canal occupying ratio (COR) and beak-type configuration on sagittal MRI are independent predictors of higher ISI grades.
- Multi-segment OLF and ISI Grade 2 independently predict poor postoperative recovery.
- Preoperative ISI grade is a critical prognostic indicator in T-OLF, aiding in risk stratification and surgical planning.
