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...
متن کاملThe ‘triradiate bump’: a novel radiographic sign that may confound assessment of acetabular retroversion
PURPOSE The triradiate cartilage transiently projects medially within the pelvic brim around the time of triradiate closure, mimicking the ischial spine sign. The purpose of this study was to characterize this newly identified radiographic sign using a longitudinal radiographic study. METHODS We identified 72 subjects from a longitudinal radiographic study of healthy adolescents, each with at...
متن کاملRadiographic markers of acetabular retroversion: correlation of the cross-over sign, ischial spine sign and posterior wall sign.
Radiological diagnosis of acetabular retroversion is based on the presence of the cross-over sign (COS), the posterior wall sign (PWS), and prominence of the ischial spine (PRISS). The primary purpose of the study was to correlate the quantitative cross-over sign with the presence or absence of the PRISS and PWS signs. The hypothesis was that both, PRISS and PWS are associated with a higher cro...
متن کاملThe 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...
