After dealing with the CT image of pedicle screw with interpolation numberical method, for pedicle screw of gradeⅠ,CT had a positive predictive value of 52.7%, a negative predictive value of 94%.,a sensitivity of 67% and a specificity of 94%; for pedicle screw of gradeⅡ, CT had a positive predictive value of 75%, a negative predictive value of 100%.,a sensitivity of 100% and a specificity of 94%.

结果：采用"低窗位、高窗宽"原则处理CT影像后，CT对于Ⅰ度椎弓根螺钉的敏感度为33%、特异度为87%、阳性预测值为32%、阴性预测值为88%。CT 对于Ⅱ度椎弓根螺钉的敏感度为100%、特异度为88％、阳性预测值为60%、阴性预测值为100%。Kapper值为0.603。

This method offer the real bases and theoretical foundation to detection of the dynamic envelop line of the pantograph.

The difference among vertebrae rotational degrees measured by conimeter, Ho's method and EPPsag was compared by Wilcoxon signed rank test.

在经椎弓根中部的CT横切面上测量两侧椎弓根螺钉进钉点连线之垂直平分线与矢状面的夹角，将EPPsag角与脊椎标本的实际旋转度、Ho's法测量结果进行Wilcoxon符号秩检验。

Methods Before the operation, the angles between the spinous process and the pedicle of vertebral arch were detected, and used to decide the direction of screws in operation. 23 cases of thoracolumbar vertebra fracture were treated with AF system in this way.
