Therefore, this study aimed to implement FE models of C-type scoliotic spine to investigate the influence of different loading conditions and vertebral rotations on variation of Cobb's angle and vertebral stress. There were three parametric FE models with different vertebral rotations.

因此本研究可望藉由胸椎C形脊柱侧弯模型探讨不同施力方式及不同椎体旋转角度对柯卜氏角度（Cobb's angle）及椎体应力分布之影响。

Our results showed that the most appropriate rib's level for applying force was below the apex of scoliotic spine. From this appropriate level, the stress delivered to its conjunctive vertebra was the highest, as 1.3~1.8 times compared with others. Furthermore, the correction of Cobb's angle was also the highest, achieved 15%. The ML force was dominant in alteration of Cobb's angle, whereas the AP force was dominant in alteration of axial vertebral rotation. In addition, initial vertebral rotation influenced neither correction nor stress.

研究结果显示由凸点椎体的下一节对应之肋骨施力能使传入椎体具最高平均应力，较其他施力位置高出1.3到1.8倍之间，对柯卜氏角度可达15%的最佳矫正率；其中侧向施力主导冠状面上的矫正，而前后向施力主导扭转角度的矫正；另外椎体初始旋转角度对侧弯矫正和应力分布均无明显影响。
