This study evaluated the relationship between maximal axial vertebra rotation (maxAVR) and other clinical and radiological indexes, compared to apical vertebra rotation (AVR) in idiopathic adolescent scoliosis (AIS).
Forty consecutive patients of AIS with Cobb angle of major curve > 40° were included. They were scanned by an EOS imaging system and had trunk rotational angle (TRA) measured by scoliometer. The correlation between variables was assessed using Pearson's correlation coefficient and loaded onto a meta-analysis model.
There were (34 girls and 6 boys) with an average age of 13.8 ± 1.6 years. AVR was maxAVR in only 47.5% (19/40) cases of the major curves and 42.3% (11/26) cases of the minor curves. The correlation between maxAVR and TRA was significantly higher than the correlation between AVR and TRA for the MT curves (p = 0.0001) and TL/L curves (p = 0.0001). On multivariate regression analysis, the magnitude of maxAVR showed a significant correlation with TRA (p = 0.0002), Cobb angle (p = 0.001), and coronal deformity angular ratio (C-DAR) (p = 0.027).
The apical vertebra was not the most rotated in most cases. The correlation between maxAVR and TRA was significantly higher than the correlation between AVR and TRA. Moreover, the maxAVR was multivariately related to TRA, Cobb angle, and C-DAR.

本研究评估了特发性青少年脊柱侧凸（AIS）中最大轴向椎体旋转（maxAVR）与其他临床和影像学指标与顶椎旋转（AVR）之间的关系。
纳入了 40 例 Cobb 角主要曲线>40°的 AIS 连续患者。他们使用 EOS 成像系统进行扫描，并使用脊柱侧凸计测量躯干旋转角（TRA）。使用 Pearson 相关系数评估变量之间的相关性，并将其加载到荟萃分析模型中。
有 34 名女孩和 6 名男孩，平均年龄为 13.8±1.6 岁。在主要曲线的 47.5%（19/40）和次要曲线的 42.3%（11/26）病例中，AVR 就是 maxAVR。MT 曲线（p=0.0001）和 TL/L 曲线（p=0.0001）的 maxAVR 与 TRA 之间的相关性明显高于 AVR 与 TRA 之间的相关性。多元回归分析显示，maxAVR 的大小与 TRA（p=0.0002）、Cobb 角（p=0.001）和冠状面畸形角度比（C-DAR）（p=0.027）显著相关。
在大多数情况下，顶椎并非旋转最大的椎体。maxAVR 与 TRA 之间的相关性明显高于 AVR 与 TRA 之间的相关性。此外，maxAVR 与 TRA、Cobb 角和 C-DAR 存在多变量关系。
