Acetabular Component Orientation in Total Hip Arthroplasty: the Role of Acetabular Transverse Ligament
نویسندگان
چکیده
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.

The role of the transverse acetabular ligament in total hip arthroplasty.
We performed a systematic literature review to evaluate the role of the transverse acetabular ligament as a reference aid when determining acetabular component anteversion in total hip arthroplasty. We conducted a literature search in the MEDLINE, EMBASE and Pubmed databases using the key words 'transverse acetabular ligament' and 'arthroplasty'. Four studies published between 2006 and 2011, re...
متن کاملThe role of the transverse acetabular ligament for acetabular component orientation in total hip replacement: an analysis of acetabular component position and range of movement using navigation software.
Orientation of the native acetabular plane as defined by the transverse acetabular ligament (TAL) and the posterior labrum was measured intra-operatively using computer-assisted navigation in 39 hips. In order to assess the influence of alignment on impingement, the range of movement was calculated for that defined by the TAL and the posterior labrum and compared with a standard acetabular comp...
متن کاملThe transverse acetabular ligament: an aid to orientation of the acetabular component during primary total hip replacement: a preliminary study of 1000 cases investigating postoperative stability.
Ensuring the accuracy of the intra-operative orientation of the acetabular component during a total hip replacement can be difficult. In this paper we introduce a reproducible technique using the transverse acetabular ligament to determine the anteversion of the acetabular component. We have found that this ligament can be identified in virtually every hip undergoing primary surgery. We describ...

متن کاملThree-Dimensional Templating for Acetabular Component Alignment During Total Hip Arthroplasty.
Appropriate placement of the acetabular cup is an important determinant of implant stability and longevity. Malposition of acetabular cups negatively influences prosthesis survival and leads to an increased dislocation rate. The objective of the study was to determine the role of 3-dimensional templating in obtaining accurate acetabular component placement in total hip arthroplasty. In this com...
