Abstract

Purpose: Distal radius fractures involving distal radioulnar joint (DRUJ) are common. After the fracture treatment, pain on the ulnar side of wrist, limitation of forearm rotation and instabilities can be remained. The purpose of this study was to address the importance of anatomical reduction for DRUJ injuries.
Methods: Of 115 cases with a distal radius fracture involving DRUJ, 61 cases involving sigmoid notch of the radius or having a ulnar styloid process base fracture were evaluated. At an average of six months follow-up, their final outcomes
were investigated using radiologic findings, functional disabilities of the arm, shoulder and hand (DASH) and visual analogue scale (VAS) pain scores and wrist motion of pronation/supination.
Results: Satisfied radiologic reduction rate was 73.8%(45/61) in average, which was most favorable in external fixator group (82.4%, 28/34). The mean functional DASH score was 29.0 points and mean VAS for pain was 5.0. The mean
range of wrist motions for pronation/supination was 59.5°/55.7°.
Conclusion: Distal radius fractures involving DRUJ should be classified into the basic categories of unstable distal radius fracture, and immediate anatomical reduction is needed by operative treatment to avoid painful forearm rotation.
