External fixation of Colles' fracture.

Radiographic and functional results of external fixation of 32 Colles' fractures were compared with the results of plaster fixation of 189 Colles' fractures. Despite the fact that the fractures treated with the external device were more unstable and comminuted, the final results were equal in both groups, and the radiographic outcome of external fixation was superior. Pin loosening decreased with predrilling rather than self-tapping. We recommend external fixation for unstable fractures of the distal forearm.
