The role of routine preoperative magnetic resonance imaging in idiopathic scoliosis: A ten years review

Study Design: Prospective study. Purpose: To determine the role of routine preoperative magnetic resonance imaging (MRI) to detect the incidence and risk factors for intraspinal anomalies in patients with idiopathic scoliosis. Overview of Literature: The incidence and risk factors for intraspinal anomalies in patients with idiopathic scoliosis are controversial, and the indications for preoperative MRI in these patients vary among centers. Methods: Information on patients with idiopathic scoliosis who were surgical candidates over 10 years (age at presentation, sex, magnitude and apex of major curve, intraspinal anomalies detected by MRI, and neurological examination results) were recorded, the patients were grouped according to the intraspinal anomaly, and the data were analyzed. Results: Of the 271 patients with idiopathic scoliosis, 27 had neuroaxial abnormalities (9.9). Of these 27 patients, 14 (52) underwent a neurosurgical procedure. Significant differences were observed in the frequency of early disease onset and male sex (p
