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. Non...
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 کاملAcetabular Component Orientation in Total Hip Arthroplasty Using Transverse Acetabular Ligament (TAL)
Objective: To assess the effectiveness of transverse acetabular ligament (TAL) as a guide for acetabular cup ante version during total hip arthroplasty and its effect on postoperative hip dislocation. Methods: This descriptive case series was on 117 patients suffering from Hip pathologies underwent elective primary total hip arthroplasties (THA). Patients were examined radiologically postoperat...
متن کاملAcetabular component orientation in total hip arthroplasty: the impact of obesity.
INTRODUCTION Acetabular component position can be an important determinant of joint stability and bearing surface wear after THA. Nonetheless, the incidence of malpositioning is high. Patient obesity, low surgeon volume, and minimally invasive approaches are known risk factors for malposition. As the incidence of obesity continues to increase, it is important to recognise its effect on intraope...
متن کاملOrientation of the acetabular component. A comparison of five navigation systems with conventional surgical technique.
We compared the orientation of the acetabular component obtained by a conventional manual technique with that using five different navigation systems. Three surgeons carried out five implantations of an acetabular component with each navigation system, as well as manually, using an anatomical model. The orientation of the acetabular component, including inclination and anteversion, and its posi...
