The

importance of radial multiplanar reconstructions for assessment of triangular fibrocartilage complex injury in CT arthrography of the wrist. Left side: Schematic coronal display of the triangular fibrocartilage complex (TFCC). While both TFCC layers originate from the sigmoid notch of the radius, the superficial (light grey) and deep (dark grey) layer of the TFCC insert at the ulnar styloid process and ulnar fovea, respectively. Right side: Schematic axial display of the dorsal and palmar radioulnar ligaments during forearm pronation (upper right), neutral position (middle right) and supination (lower right) from an axial perspective

The

importance of radial multiplanar reconstructions for assessment of triangular fibrocartilage complex injury in CT arthrography of the wrist. 35-year-old man with ulnar-sided wrist pain. Axial planes of the distal radioulnar joint illustrate the difference between multiplanar reconstructions after CT arthrography. a coronal reconstruction. b radial reconstruction with the rotating center atop the ulnar styloid process. c radial reconstruction with the rotating center in the ulnar fovea

The

importance of radial multiplanar reconstructions for assessment of triangular fibrocartilage complex injury in CT arthrography of the wrist. Left side: Schematic illustration of the Atzei classification for peripheral lesions of the triangular cartilage complex (TFCC). Right side: Radially reconstructed CT images from different patients depicting the corresponding ulnar-sided TFCC pathologies. Additional central discus alterations are present in the images for stages 3A and 5
