Adolescent Idiopathic Scoliosis and the Presence of Spinal Cord Abnormalities

This study reports a higher than expected frequency of spinal cord abnormalities in patients with the preoperative diagnosis of adolescent idiopathic scoliosis. The indications for preoperative magnetic resonance imaging before spinal fusion vary among physicians; however, strict adherence to previously published recommendations as listed in this report is advisable. It appears from the results of this study that by following these guidelines, small syrinxes may remain undetected, but the clinical significance of this is unknown.
