髋臼后倾有3种定义：真实（解剖）后倾、平面（影像学）后倾和手术后倾。虽然平面版本可以在标准X线片上测量，但当应用于金属背衬髋臼部件时，测量可能不准确。然而，另一个扭转角在成角的髋关节侧位X线片（轴位侧位片）上显示得很清楚，这个角度很容易区分前倾和后倾。如果X射线束的角度是已知的或标准化的，则在轴侧视图上测量的扭转角可以转换为其他扭转角。这些转换列线图。在大多数情况下，轴侧位片上测量的髋臼版本非常接近平面版本。
There are 3 definitions of acetabular version: true (anatomic) version, planar (radiographic) version, and operative version. Although planar version can be measured on standard radiographs, the measurement may be inaccurate when applied to metal-backed acetabular components. However, another version angle is depicted clearly on an angled, cross-table lateral radiograph of the hip—the axiolateral view, and this angle readily distinguishes anteversion from retroversion. If the angle of the xray beam is known or is standardized, version measured on the axiolateral view can be converted to the other version angles. Nomograms for these conversions are presented. In most cases, acetabular version measured on the axiolateral radiograph closely approximates planar version.
