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 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.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
