1Preliminary remarks

These are partial articular fractures. These fractures demand accurate reduction since they involve the articular surface.

Fractures involving the dorsal rim of the distal radius represent a spectrum of injuries, with variation in the size of the dorsal fragments. Large fragments may be suitable for plating or even lag screw fixation, while smaller fragments may require fixation with K-wires or suture anchors.

In some cases, the fracture of the dorsal rim is associated with a radial styloid fracture as well, and there is greater instability and risk of dislocation of the carpus. These fractures usually require a dorsal plate to hold the dorsal fragments and a radial plate to hold the radial styloid.
