Radiographic Evaluation of the Distal Radioulnar Joint: Technique to Detect Sigmoid Notch Intra-Articular Screw Breach in Distal Radius Fractures

Conclusions: The “extended tangential view” and the “sunrise view” improved one's ability to identify DRUJ screw breach and for directing screw repositioning over standard views. We recommend the “sunrise” and “extended tangential” view be obtained intraoperatively to help guide clinical decision-making. Although the “extended tangential view” is more easily obtained with a mini c-arm than the “sunrise view,” both views should be considered to fully evaluate the DRUJ joint. Clinical Relevance: Both the “extended tangential” and “sunrise” views help improve sigmoid notch visualization, identify DRUJ screw penetrance, direct screw positioning, and prevent unnecessary screw repositioning.
