| Abstract: | Previously developed criteria of normal distal radioulnar joint (DRUJ) axial geometry were applied to routine magnetic resonance
(MR) images of 50 wrists. All wrists lacked clinically evident DRUJ instability. An attempt to apply the three geometric criteria
to seven of the cases was not possible, since the prescribed landmarks were not visible. The remaining 43 cases were retrospectively
divided into a symptomatic group (25 wrists), with clinical abnormalities referable to the ulnar side of the wrist, and an
asymptomatic group (18 wrists), with no such abnormalities. Abnormal DRUJ geometry was found in 12 symptomatic and 2 asymptomatic
wrists. This difference between the groups is significant (p=0.02), suggesting that many symptomatic wrists exhibit different DRUJ geometry than is found in most asymptomatic wrists. |
