Displaced distal radius fractures. A comparative study of early results following external fixation, functional bracing in supination, or dorsal plaster immobilization.

A comparison of the radiographical and functional results after displaced distal radius fractures in 41 patients treated by external fixation (EF), 36 patients treated by functional bracing in supination (FUSU), and 49 patients treated by dorsal plaster immobilization (DPI) was performed. The rate of initial complications after EF was 53%, compared with 22% after FUSU and 14% after DPI. The radiographical result after EF was significantly better than after nonoperative treatment, but the functional result after 3 and 6 months demonstrated no significant difference between the three series. Consequently, EF and FUSU do not restore wrist function faster than conventional plaster treatment (DPI), but EF improves the radiographical result, though the rate of complications is higher.
