Optimal imaging of acetabular trauma

In 19 cases of acetabular fracture it is shown that CT plus volumetric 3D reconstructions displayed as video loops about horizontal and vertical axes of rotation can replace the traditional imaging combination of CT plus multiple plain radiographs while offering significant advantages. Overlying bowel content or foreign matter obscured detail in 36 of 45 plain radiographic views, and positioning or radiographic technique was suboptimal in 21. 3D reconstructions completely eliminated these problems. Elimination of five plain radiographs results in a skin radiation dose savings of 5 rad. No difficult or painful patient positioning was required beyond that necessary for the standard CT scan
