[Experimental study on a plaster cast in fractures of the carpal scaphoid. Clinical deductions].

The displacement of the proximal and distal fragments of fractures of the carpal scaphoid have been studied in fresh cadavers. In 10 subjects, a comparison has been made between a below-elbow plaster, a moulded plaster gauntlet and an above-elbow plaster. The most satisfactory immobilisation has been obtained with a moulded plaster gauntlet incorporating the proximal phalanx of the thumb and leaving the elbow free.
