[Purpose] The purpose of this study was to examine the relationship between the degree of thoracic deformity (TD) and the angle formed by a line drawn on transverse plane computed tomography (CT) images, connecting the sternum and the spinous process of the vertebrae at the level of the xiphisternum, and the perpendicular line from the floor (ANGLE), in individuals with severe motor and intellectual disorders (SMID). [Subjects] Twenty seven individuals with SMID were examined. [Methods] CT transverse images were acquired at the level of the xiphisternum of each patient. Two protocols were used to measure the anteroposterior (AP) and laterolateral (LL) diameters. The largest AP diameters were measured along a perpendicular line from the floor (protocol 1) and the line from the midline of the sternum to the spinous process of the vertebrae (protocol 2). The largest LL diameters were measured along the lines perpendicular to the AP diameters in each protocol. The ratios of the AP to LL diameters and the difference between the ratios of protocols 1 and 2 (DIFFERENCE) were calculated. [Results] Moderate to good correlation between DIFFERENCE and ANGLE was observed, and DIFFERENCE became larger with increasing ANGLE. [Conclusions] These results show that ANGLE indicates the degree of TD.
[目的]本研究旨在探讨重度运动和智力障碍（SMID）患者的胸廓畸形（TD）程度与横断位计算机断层扫描（CT）图像上连接剑突水平处胸骨与椎体棘突的直线与地面垂直线所形成的角度（ANGLE）之间的关系。[对象]对27例SMID患者进行了检查。[方法]在每位患者的剑突水平获取CT横断图像。采用两种方案测量前后径（AP）和左右径（LL）。最大AP径沿着地面垂直线（方案1）以及从胸骨中线到椎体棘突的直线（方案2）进行测量。在每个方案中，沿着与AP径垂直的线测量最大LL径。计算AP与LL径的比值以及方案1和方案2比值之间的差值（DIFFERENCE）。[结果]观察到DIFFERENCE与ANGLE之间存在中度到良好的相关性，并且DIFFERENCE随着ANGLE的增加而增大。[结论]这些结果表明ANGLE可指示TD的程度。
