Correlation 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...

Diagnostic 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...

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...

Correlation of pelvic incidence with radiographical parameters for acetabular retroversion: a retrospective radiological study

BACKGROUND Pelvic incidence (PI) has been linked to several degenerative processes within the spinopelvic system. Acetabular retroversion is a recognised risk factor for osteoarthritis of the hip. We therefore hypothesised that these two factors might be part of a specific anatomical variant associated with degenerative changes. This study was performed to clarify this issue. METHODS The pelv...
