Overview

Retrospective cohort study reveals myelography identifies undetected stenosis and alters operative plans in degenerative lumbar scoliosis, indicating MRI alone understates spinal canal narrowing.

Key Points

  • To evaluate the clinical utility of myelography and CT myelography compared to MRI in assessing degenerative lumbar scoliosis and determining its influence on surgical decision-making.
  • Retrospective review of 21 patients with degenerative lumbar scoliosis selected from 270 consecutive patients who underwent myelography between 2006 and 2009.
  • A spine surgeon formulated initial operative plans using MRI, then re-evaluated plans after reviewing subsequent myelograms and CT myelograms for additional pathology.
  • Myelography identified spinal stenosis abnormalities not visible on MRI in 18 of 21 patients (85.7%), with supine CT myelography revealing additional information over supine MRI in 4 patients.
  • Surgical management plans were modified in 7 of 21 patients (33%) based on myelographic findings.
  • No complications occurred across the entire cohort of 270 myelography procedures performed during the study period.
