摘要

Peri-acetabular osteotomy is an established surgicaltreatment for symptomatic acetabular dysplasia in young adults.An anteroposterior radiograph of the pelvis is commonly used toassess the extent of dysplasia as well as to assess post-operativecorrection. Radiological prognostic factors include the lateralcentre-edge angle, acetabular index, extrusion index and the acetabularversion. Standing causes a change in the pelvis tilt which can altercertain radiological measurements relative to the supine position.This article discusses the radiological indices used to assess dysplasiaand reviews the effects of patient positioning on these indiceswith a focus on assessment for a peri-acetabular osteotomy. Intra-operatively,fluoroscopy is commonly used and the implications of using fluoroscopyas a modality to assess the various radiological indices along withthe effects of using an anteroposterior or posteroanterior fluoroscopicview are examined. Each of these techniques gives rise to a slightly differentimage of the pelvis as the final image is sensitive to the positionof the pelvis and the projection of the x-ray beam.Cite this article: Bone Joint J 2014;96-B:1155–60.
