Abstract:

Acetabular component anteversion(ACA) is a direction parameter ofacetabularcomponent in total hip arthroplasty(THA). ACA is routinely controlled intraoperatively and assessed postoperatively for its paramountimpact on outcome of THA.Recent advance in related researches has renewed our knowledge on the clinical significance of ACA.The long-followed Lewinnk’s "safe zone" has been challenged by new proofs and novel standards for ideal ranges of ACA from more integrative and individual perspectives are emerging.Radiographic measurement of ACA is essential for evaluation of THA outcome. However, ACAcannot be directly measured from conventional hip radiographs. Efforts since the 1970s have turned out several methods to calculate anteversion from measurements on radiographs, but none of them can obviatesimultaneously disadvantages of excessive subjective error and complexity in manipulation. Based on the literature, this article reviewed the definitions, clinical relevance and imaging measurement of acetabular component anteversion with an aim to provide reference for the clinical practice and related research of total hip arthroplasty.
