The orientation of an acetabulum or an acetabular prosthesis may be described by its inclination and anteversion. Orientation can be assessed anatomically, radiographically, and by direct observation at operation. The angles of inclination and anteversion determined by these three methods differ because they have different spatial arrangements. There are therefore three distinct definitions of inclination and anteversion. This paper analyses the differences between the definitions and provides nomograms to convert from one to another. It is recommended that the operative definitions be used to describe the orientation of prostheses and that the anatomical definitions be used for dysplastic acetabula.
髋臼或髋臼假体的方位可通过其倾斜度和前倾角来描述。方位可通过解剖学、影像学以及手术中的直接观察来评估。由这三种方法确定的倾斜角和前倾角有所不同，因为它们具有不同的空间布局。因此，倾斜度和前倾角有三种不同的定义。本文分析了这些定义之间的差异，并提供了用于相互转换的列线图。建议使用手术定义来描述假体的方位，而使用解剖学定义来描述发育不良的髋臼。
