Abstract Aim This systematic review aims to understand the relationship between version abnormalities of femur and acetabulum in patients with primary secondary femoroacetabular impingement (FAI). Method A was conducted according PRISMA guidelines. computer-based search performed using EMBASE, MEDLINE, PubMed Cochrane databases for articles relating torsional FAI, Legg-Calve-Perthes disease (LC...

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...

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...

PURPOSE The orientation of the acetabular component in metal-on-metal hip resurfacing arthroplasty affects wear rate and hence failure. This study aimed to establish if interpretation of pelvic radiographs with TraumaCad software can provide a reliable alternative to CT in measuring the acetabular inclination and version. METHODS TraumaCad was used to measure the acetabular orientation on AP ...

OBJECTIVES This study aims to define a quantitative measurement method for acetabular version in a standard anteroposterior hip radiograph, assess the intraobserver and interobserver agreements of this method, and compare it with the gold standard computed tomography (CT). PATIENTS AND METHODS Anteroposterior standard hip radiographs and simultaneously taken transverse acetabular CT sections ...

BACKGROUND Although cross-table lateral radiographs are commonly used to measure acetabular component version after THA, recent studies suggest that CT-based measurement is more accurate. This has been attributed to variations in pelvic tilt, pelvic rotation, and component inclination. Furthermore, it has been suggested, based on limited data, that even with ideal positioning of the cross-table...

Lewinnek et al described a safe zone of acetabular component placement in Total Hip Arthroplasty (THA) to reduce complications. This safe zone is between 10-30 degrees of version and 30-50 degrees of inclination 1 . Callanan et al. reports only 53% of acetabular cups were within Lewinnek’s Safe Zone of optimal cup placement (62% within the abduction safe zone, 79% within the version safe zone)....

BACKGROUND AND PURPOSE The appearance of acetabular version differs between the supine and weight bearing positions in developmental dysplasia of the hip. Weight bearing radiographic evaluation has been recommended to ensure the best coherence between symptoms, functional appearance, and hip deformities. Previous prevalence estimates of acetabular retroversion in dysplastic hips have been estab...

The orientation of acetabular component is influenced by pelvic tilt, body position and individual variation in pelvic parameters. Most adverse events attribute to improper positioning of the acetabular component in the functional position. There is evidence that the orientation of the pelvis changes from the supine to standing position, consequently changing the orientation of acetabular cup v...
