OBJECTIVE
Researchers have identified potential errors in the Gonstead method's analysis of pelvic alignment resulting from -axis rotation of the pelvis on the anteroposterior (A-P) radiograph. The purpose of this article is to propose a method that can be used to determine the magnitude of -axis rotation of the pelvis present on the A-P radiograph.
METHODS
In this proposed method, measurements are obtained from the patient and from the lateral and A-P radiographs. With a mathematical method, these measurements are used with the focal film distance to calculate the degree of pelvic rotation present on an individual A-P radiograph.
RESULTS
This method may help with the accuracy of measurement of pelvic -axis rotation on the A-P radiograph.
CONCLUSION
The method proposed can be used to calculate the magnitude of pelvic -axis rotation on an A-P radiograph.
目的
研究人员已确定在前后位（A-P）X线片上，骨盆围绕矢状轴旋转会导致冈斯特德（Gonstead）方法在分析骨盆对线时出现潜在误差。本文的目的是提出一种可用于确定A-P X线片上骨盆矢状轴旋转幅度的方法。
方法
在这种提出的方法中，从患者以及侧位和A-P X线片上获取测量值。通过一种数学方法，将这些测量值与焦-片距一起用于计算个体A-P X线片上骨盆旋转的程度。
结果
该方法可能有助于提高A-P X线片上骨盆矢状轴旋转测量的准确性。
结论
所提出的方法可用于计算A-P X线片上骨盆矢状轴旋转的幅度。
