The mechanism of the left-right handedness and pathogenesis of adolescent idiopathic scoliosis (AIS) is still unclear. We speculated that the pathogenesis of AIS may different from the mechanism of the laterality of convex curve pattern in AIS patients. This laterality may have correlation with the right dominance of handedness. The location and gravity of heart and aorta may determine the trend of lateral flexion and axial rotation of normal spine, which may be the reason of both left-right handedness and left-right convex curve pattern of AIS.
左右利手的机制和青少年特发性脊柱侧凸（AIS）的发病机制尚不清楚。我们推测 AIS 的发病机制可能与 AIS 患者凸侧曲线模式的偏侧性机制不同。这种偏侧性可能与手的右优势有关。心脏和主动脉的位置和重力可能决定了正常脊柱的侧屈和轴向旋转趋势，这可能是 AIS 左右利手和左右凸侧曲线模式的原因。
