External fixation of distal radial fractures: 3 or 5 weeks of external fixation

In a retrospective study we compare the functional and radiographical resul ts of 2 groups of patients with unstable distal radial fractures treated wi th external fixation. In Group 1, 20 patients with 21 fractures were treate d with external fixation for 3 weeks followed by a cast for 2 weeks. In Gro up 2, 16 patients were treated with external fixation for 5 weeks. The func tional outcome was good in both treatment groups with no significant differ ence between the results in the two groups. Radiologically, Group I had les s radial shortening than Group II, but there was no difference in the derge e of dorsal angulation.
