Partial articular, sagittal multifragmentary radial fracture, involving scaphoid fossa

These fractures may also be multifragmentary. These are still classified by AO/OTA as 2R3B1.1.

Care must be taken to identify associated fractures extending into the palmar rim of the distal radius. These injury components are best visualized using CT scans.
These fractures are also often associated with scapholunate interosseous ligament injury.
