Abstract:
[Objective]To demonstrate the shift of the spinal cord to the concave side of the spinal canal in adolescent patients with idiopathic thoracic scoliosis,to investigate possible cause of the shift of the spinal cord and to explore its clinical relevance.[Method]Thirty-nine adolescents with idiopathic thoracic scoliosis were recruited in this study.Cobb's angle,relative apical translation and relative trunk shift of the major thoracic curves were recorded from standing posteroanterior roentgenography of the whole spine.The shift of the spinal cord was determined through the measurements of distance between the spinal cord and the medial walls of the pedicles on the convex and concave sides,which were performed in transverse magnetic resonance images of the spinal canal in the major thoracic curves(T5~12).The variations of the shift of the spinal cord were determined,and the relationships between the shift of the spinal cord at the apical region and Cobb's angle,and between that and the relative apical vertebral translation were analyzed.[Result]In the region of the major thoracic curves,the distance from the spinal cord to the pedicle on the convex side was significantly less than the distance to the pedicle on the concave side(P
