The normal spine is not a symmetrical structure, as has been appreciated for a long time. The reason why the main thoracic vertebrae in idiopathic scoliosis predominantly rotate to the left at the infantile age and to the right at the adolescent age is unclear. We provided an in-depth analysis of the rotational patterns of the normal growing and adult spine in relation to closure of the neurocentral junctions, organ anatomy and the convexity of the curve in idiopathic scoliosis. We believe that the delicate upright human spino-pelvic balance can be disturbed by a multitude of offenses and consequently an idiopathic scoliosis will develop due to the rotational instability. From our results it can be concluded that once this rotation starts to occur, it will naturally follow the pre-existent rotational patterns that we have demonstrated to exist already in the normal spine.
正常脊柱并非对称结构，这一点早已为人所知。特发性脊柱侧凸中，主要胸椎在婴儿期多向左旋转，而在青少年期多向右旋转，其原因尚不清楚。我们深入分析了正常生长和成年脊柱的旋转模式，这些模式与神经中央关节闭合、器官解剖结构以及特发性脊柱侧凸中曲线的凸度有关。我们认为，多种因素会扰乱人体微妙的脊柱-骨盆平衡，进而因旋转不稳定而导致特发性脊柱侧凸的发生。从我们的研究结果可以得出结论，一旦这种旋转开始发生，它将自然遵循我们已证明在正常脊柱中已然存在的先前旋转模式。
