Axial vertebral rotation and Cobb's angle are essential parameters for analysing adolescent idiopathic scoliosis. This study's scope evaluates the validity and absolute reliability of application software based on a new mathematical equation to determine the axial vertebral rotation in digital X-rays according to Raimondi's method in evaluators with different degrees of experience.
Twelve independent evaluators with different experience levels measured 33 scoliotic curves in 21 X-rays with the software on three separate occasions, separated one month. Using the same methodology, the observers re-measured the same radiographic studies three months later but on X-ray films and in a conventional way.
Both methods show good validity and reliability, and the intraclass correlation coefficients are almost perfect. According to our results, the software increases 1.7 times the validity and 1.9 times the absolute reliability of axial vertebral rotation on digital X-rays according to Raimondi's method, compared to the conventional manual measurement.
The intra-group and inter-group agreement of the measurements with the software shows equal or minor variations than with the manual method, among the different measurement sessions and in the three experience groups. There is almost perfect agreement between the two measurement methods, so the equation and the software may be helpful to increase the accuracy in the axial vertebral rotation assessment.
椎体轴向旋转和 Cobb 角是分析青少年特发性脊柱侧凸的重要参数。本研究的范围是评估基于一种新数学方程的应用软件的有效性和绝对可靠性，该软件可根据 Raimondi 方法在不同经验程度的评估者中确定数字 X 光片中的椎体轴向旋转。
12 名具有不同经验水平的独立评估者，分三次、每次间隔一个月，使用该软件测量了 21 张 X 光片中的 33 条脊柱侧弯曲线。三个月后，观察者使用相同方法，但在 X 光片上以传统方式重新测量了相同的影像学研究。
两种方法均显示出良好的有效性和可靠性，组内相关系数几乎完美。根据我们的结果，与传统手动测量相比，该软件使根据 Raimondi 方法在数字 X 光片上进行椎体轴向旋转测量的有效性提高了 1.7 倍，绝对可靠性提高了 1.9 倍。
在不同测量时段和三个经验组中，使用该软件进行测量的组内和组间一致性与手动方法相比，显示出相同或更小的差异。两种测量方法之间几乎完全一致，因此该方程和软件可能有助于提高椎体轴向旋转评估的准确性。
