Abstract

Purpose: 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).

Methods: 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.

Results: 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).

Conclusions: 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.

Level of evidence: Level II, diagnostic.

初步评估青少年特发性脊柱侧凸的最大轴向椎体旋转与旋转畸形之间的关系。

目的：本研究评估了特发性青少年脊柱侧凸（AIS）的最大轴椎旋转（maxAVR）与其他临床和放射学指标之间的关系，并与顶椎旋转（AVR）进行了比较：方法：连续纳入 40 名主要曲线 Cobb 角大于 40° 的 AIS 患者。用 EOS 成像系统对他们进行扫描，并用脊柱侧弯计测量躯干旋转角度（TRA）。使用皮尔逊相关系数评估变量之间的相关性，并将其载入荟萃分析模型：结果：34 名女孩和 6 名男孩的平均年龄为（13.8 ± 1.6）岁。仅有 47.5%（19/40）的大弯患者和 42.3%（11/26）的小弯患者进行了 maxAVR。对于 MT 曲线（p = 0.0001）和 TL/L 曲线（p = 0.0001），maxAVR 与 TRA 之间的相关性明显高于 AVR 与 TRA 之间的相关性。在多变量回归分析中，maxAVR 的大小与 TRA（p = 0.0002）、Cobb 角度（p = 0.001）和冠状畸形角度比（C-DAR）（p = 0.027）呈显著相关：结论：在大多数病例中，顶椎并非旋转最多的椎体。结论：大多数病例的顶椎不是旋转最多的，最大AVR和TRA之间的相关性明显高于AVR和TRA之间的相关性。此外，最大AVR与TRA、Cobb角和C-DAR有多重相关性：证据级别：二级，诊断。
