ADDITIONAL COMPUTED TOMOGRAPHY IS OF MINOR VALUE

Interobserver reliability of the AO system of classification of fractures of the distal radius was assessed using plain radiographs and CT. Five observers classified 30 Colles'-type fractures using only plain radiographs; two months later they were reclassified using CT in addition.

Interobserver reliability was poor in both series when detailed classification was used. By reducing the categories to five, interobserver reliability was slightly improved, but was still poor. When only two AO types were used, the reliability was moderate using ...
