The authors investigated the statistical relationship and significance between the transverse and sagittal plane proximal articular set angles both radiographically and intraoperatively. The analysis revealed a highly significant difference between the means of the respective measurements. Although the radiographic and intraoperative findings were found to be related for the transverse plane proximal articular set angle, the transverse plane PASA was approximately 7 degrees greater when measured intraoperatively. The concept of a sagittal plane PASA was also introduced. The significance of accurate measurements in the surgical correction of hallux valgus was also examined.
作者通过影像学和术中测量研究了横平面与矢状面近端关节设定角度之间的统计学关系及显著性。分析显示各测量均值之间存在高度显著差异。虽然发现横平面近端关节设定角度的影像学和术中测量结果相关，但术中测量的横平面近端关节设定角度（PASA）大约大7度。还引入了矢状面PASA的概念。同时也研究了在拇外翻手术矫正中进行精确测量的意义。
