External fixation or a cast for Colles' fracture

Abstract

Function and radiographic position were evaluated 2.5 years after a displaced distal radial fracture had been reduced and treated by external fixation in 40 patients as compared with immobilization in a below-the-elbow cast in 91 patients. Wrist function was better after external fixation associated with less residual displacement. The frequency of arthrosis was the same in both series. The rate of complications after external fixation was higher than after immobilization in a plaster cast, notably sensory disturbances in the thumb. This complication can probably be eliminated by modifying the surgical technique.
