[Distal radius fractures : Update on imaging]

Abstract

Distal radius fractures are associated with high individual and socioeconomic relevance. Optimized radiography and computed tomography (CT) imaging are essential for individualized therapy planning. Plain CT imaging with 3D reconstruction and digital removal of the carpus and ulna is helpful for choosing the surgical approach in the presence of intra-articular radius fractures. If the fracture line leads towards the scapholunate compartment, ligamentous injury requiring treatment can be detected or ruled out before surgery with the help of direct CT arthrography (CTA). Acquisition of imaging data and morphometrical analysis must be standardized and reproducible. In the diagnostics of distal radius fractures it is necessary for radiologists and surgeons to use a unified fracture classification.
