Three-dimensional CT imaging for the intra-articular fracture of distal radius

Three-dimensional CT imaging for the fracture of distal radius was performed in 47 patients including 12 with the intra-articular fracture of distal radius. These images were compared with those of plain radiographs and computed tomography. Three-dimensional CT was helpful in detecting the displacement of the fracture and in determining the location and the direction of the fragment. By elimination technique, detailed information could be obtained and the eliminated axial views of intra-articular fracture revealed the details of damage of the joint surface. It was helpful to classify the intra-articular fracture of distal radius. (author)
