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


CONCLUSIONS
We conclude from this preliminary study that the transverse acetabular ligament can aid positioning of the acetabular component of a THR. It defines the version of the acetabular component without the need for external instrumentation, and is independent of the position of the patient. Level of Evidence IV; Prospective Study.
