Abstract:

BACKGROUND: Placement angle of the acetabular cup is a key factor for successful operation. Acetabular abduction and acetabular anteversion are two important parameters to evaluate the reasonableness of the prosthesis placement.
OBJECTIVE: To review the measurement methods of the acetabular anteversion as well as the relationship between the acetabular anteversion and the prosthesis providing theoretical guidance for reasonable placement of the prosthesis.
METHODS: A computer-based search of Wanfang, VIP and PubMed was performed for articles addressing the acetabular anteversion in total hip arthroplasty published before August 2011. The keywords were “total hip arthroplasty, acetabular anteversion, artificial joint, measurement”. Articles in the same field published recently or in authoritative journals were preferred. Totally 285 articles were retrieved, and finally 25 articles meeting the inclusive criteria were included.
RESULTS AND CONCLUSION: The accuracy placement of the acetabular prosthesis is very important for the stability of the joints. Most scholars now believe that the acetabular prosthesis is placed reasonably with the acetabular abduction of 40°-45° and the acetabular anteversion of 15°-20°.
