ACETABULAR COMPONENT ORIENTATION IN TOTAL HIP ARTHROPLASTY: THE ROLE OF ACETABULAR TRANSVERSE LIGAMENT

ABSTRACT Objective: The aim of our study is to present the benefit of using the transvers acetabular ligament for intraoperative determination of the anteversion of acetabular component. Methods: Twenty-one total hip arthroplasties were performed. The transverse acetabular ligament was identified and used as a guide to position the acetabular component. Results: The mean anteversion angle was 16.9. None of the patients studied sustained a postoperative dislocation during this short follow-up period. Conclusion: We conclude from this preliminary study that the transverse acetabular ligament...
