To our knowledge, the acetabular orientation consists of two components, anteversion (version) and abduction (inclination). The relevant definitions are frequently confused. Anteversion has several definitions including anatomical anteversion (true anteversion), radiographic anteversion (planar anteversion), operative anteversion, CT standardized anteversion, and Liaw's anteversion. Similarly, abduction also has a few definitions including anatomical inclination, radiographic inclination, and operative inclination. Murray clarified anatomical, radiographic, and operative definitions of anteversion and inclination and provided the mathematical relationships between these different definitions (1). CT standardized anteversion and Liaw's anteversion are other definitions to solve this positioning problem (2,3). The authors provided us with good knowledge about clinical significance of acetabular orientation. However, the authors did not clearly mention relevant definitions of prosthetic position. According to Murray's formula, we used anatomical anteversion ( 30 ) and inclination (35 , 55 ) as a standard and calculated anteversion and inclination under other definitions (Table 1). CT standardized anteversion and Liaw's anteversion are both more complex and require more data to be calculated. |
