Evaluation of acetabular fractures with two- and three-dimensional CT. Review uri icon

Overview

abstract

  • The authors applied a widely used radiographic system of classifying acetabular fractures to axial computed tomographic (CT) scans and three-dimensional reconstructions in over 100 cases. In the classification system, fractures are analyzed according to the extent of involvement of two acetabular columns--the posterior and the anterior. To provide a better understanding of the CT anatomy of the acetabulum, the authors defined the boundaries of the columns on axial CT scans. They illustrated the most common fractures (posterior wall, transverse, transverse with posterior wall, and both columns) with radiographs, axial CT scans, and three-dimensional reconstructions. Axial CT scans readily demonstrated the fractures and presence of intraarticular fragments. Three-dimensional images helped in understanding the precise plane of the fracture, the degree of disruption of the articular surface, and spatial relationships of fragments. Although present three-dimensional CT is not without limitations, the authors believe that the technique is valuable and that, in their experience, it has facilitated preoperative planning.
