Arthrography using 60 per cent Urografin was done on twenty fresh
cadaver wrist joints. The wrists were then dissected and the arthrographic
picture was correlated with the anatomical findings. The study showed that
the contrast solution exactly delineated the radiocarpal joint cavity. It
passed through all apertures into the adjacent joints. the arthrographic
picture accurately corresponded to the anatomical observations. The pattern
of a normal arthrogram was thus established. The preliminary results of a
parallel clinical study in forty-nine patients are briefly described. I
concluded that contrast arthrography can be helpful in the diagnosis of
several conditions that show no findings on plain radiographs.
