The effect on pulmonary function of all three dimensions of the scoliotic deformity was analyzed with computer tomography in 33 patients with thoracic idiopathic scoliosis. Both static (total lung capacity [TLC], vital capacity [VC] and functional residual capacity [FRC] ) and dynamic volumes (forced expiratory volumes in one second [FEV-1]) were negatively correlated to the lateral deformity and, to a lesser degree, to rotation. Of the computer tomography variables reflecting kyphosis, the sagittal diameter was correlated positively to all lung volumes though negatively to the quotient FRC/TLC while the KLi was correlated positively to VC and FEV1. The conclusion is drawn that the Cobb angle gives the most accurate estimation of lung volume compromise and that operative treatment should aim of reducing the lateral dislocation of the vertebrae and at maintaining normal sagittal thoracic curve.
利用计算机断层扫描分析了33例胸椎特发性脊柱侧凸患者脊柱侧凸畸形三维结构对肺功能的影响。静态肺容量（肺总量[TLC]、肺活量[VC]和功能残气量[FRC]）和动态肺容量（一秒用力呼气量[FEV-1]）均与侧方畸形呈负相关，与旋转畸形的相关性较小。在反映后凸畸形的计算机断层扫描变量中，矢状径与所有肺容量呈正相关，与FRC/TLC比值呈负相关，而KLi与VC和FEV1呈正相关。得出的结论是，Cobb角能最准确地估计肺容量受损情况，手术治疗应旨在减少椎体的侧方移位并维持正常的胸椎矢状曲线。
