The relationship between acetabular retroversion and osteoarthritis of the hip.
Excessive acetabular cover secondary to a retroverted acetabulum causes pincer impingement, which may cause early osteoarthritis of the hip. Our aim was to determine if there was a relationship between acetabular version and osteoarthritis of the hip. Using image processing and analysis software we studied 117 CT images of the hip in patients aged less than 65 years who had undergone a CT virtu...
متن کاملDiagnostic Value of Ischial Spine Sign in Patients with Acetabular Retroversion
Background: Acetabular Retroversion (AR) is a hip disorder and one of the causes of pain in this area. Evaluationof positive Cross Over Sign (COS) on AP X-Rays of the hip is currently the best method of diagnosis of AR. Severalstudies have measured co-existence of Ischial Spine Sign (ISS) in patients with AR. In this study we evaluated thediagnostic value of ISS in confirmation of AR and compar...
متن کاملThree-dimensional CT analysis to determine acetabular retroversion and the implications for the management of femoro-acetabular impingement.
This study examined the relationship between the cross-over sign and the true three-dimensional anatomical version of the acetabulum. We also investigated whether in true retroversion there is excessive femoral head cover anteriorly. Radiographs of 64 hips in patients being investigated for symptoms of femoro-acetabular impingement were analysed and the presence of a cross-over sign was documen...
متن کاملCorrelation between radiographic measures of acetabular morphology with 3D femoral head coverage in patients with acetabular retroversion
BACKGROUND AND PURPOSE Acetabular retroversion may result in anterior acetabular over-coverage and posterior deficiency. It is unclear how standard radiographic measures of retroversion relate to measurements from 3D models, generated from volumetric CT data. We sought to: (1) compare 2D radiographic measurements between patients with acetabular retroversion and normal control subjects, (2) com...
متن کاملDevelopmental dysplasia of the hip: is acetabular retroversion a crucial factor?
OBJECTIVE The objective of this study was to investigate a possible relation between congenital hip dysplasia and acetabular retroversion and to explore the eventual influence of the latter in the surgical decision for periacetabular osteotomy. MATERIALS AND METHODS We assessed the classical morphological characteristics of both hips, with an additional newly described retroversion index. The...
