Partial articular, sagittal simple radial fracture, involving scaphoid fossa

These simple partial articular fractures involve the radial (lateral) column of the distal radius. These fractures demand accurate reduction since they involve the articular surface.

These are classified by AO/OTA as 2R3B1.1.

This fracture pattern is associated with a high incidence of injury to the scapholunate interosseous ligament (SLIL). They are shearing fractures of the joint surface.
