Exposing the transverse acetabular ligament in the presence of large floor osteophytes in primary total hip arthroplasty

摘要

Background/objective: The transverse acetabular ligament (TAL) can be used to position the acetabular cup and may help to improve the accuracy of primary total hip arthroplasty (THA). However, because the TAL may be covered by osteophytes, the ability to find the TAL varies greatly in the reported literature. In the present study, we introduce 2 methods and make a comparison between them to identify the easier procedure for finding an osteophyte-covered TAL.
