Paediatric pelvic corrective surgery for developmentally dysplastic hips requires that the acetabular roof is angulated to improve stability and reduce morbidity. Accurate bony positioning is vital in a weight-bearing joint as is appropriate placement of metalwork without intrusion into the joint. This can often be difficult to visualise using conventional image intensifier equipment in a 2D plane. The ARCADIS Orbic 3D image intensifier produces CT-quality multi-axial images which can be manipulated intra-operatively to give immediate feedback of positioning of internal fixation. The reported radiation dose is 1/5 and 1/30 of a standard spiral CT in high and low quality modes, respectively.Background
