1Preliminary remarks

These are radiocarpal dorsal fracture dislocations. They are the result of higher energy trauma, can have associated soft-tissue injuries, and are often found in polytrauma cases.

The injury is characterized by multifragmentary dorsal rim fractures and dorsal dislocation of the carpus.

If the distal radial fragments are predominantly dorsal, they may be held with dorsally applied plates, but if there is a significant radial styloid fragment, this is help more effectively with a radial plate (see Dorsoradial double plating).

Reduction and fixation can be performed using dorsally applied plates, although reduction and stabilization by external fixation may be chosen (at least initially) because of marked swelling.
