Abstract

The purpose of this study was to investigate the necessity for surgical fixation of basal fractures of the ulnar styloid without distal radioulnar joint (DRUJ) instability, after stabilization of associated distal radial fractures using an anterior plate. This single-centre, prospective, randomized controlled trial, conducted between 2015 to 2021, included 43 patients in each study arm who were randomized to either fixation (Group A) or non-operative treatment (Group B) of the ulnar styloid. The mean follow-up period was 24 months (SD 5.2) in Group A and 23.9 months (SD 5.5) in Group B. At the final follow-up, patients were evaluated by the Disabilities of the Shoulder, Arm, and Hand (DASH) score, the Modified Mayo Wrist Score (MMWS), the visual analogue scale (VAS) for pain, the grip strength, wrist range of motion. The DASH score was 6 (SD 2.6) in Group A and 6 (SD 2.4) in Group B; the MMWS was 87 (SD 5.6) in Group A and 87 (SD 5.6) in Group B; and the grip strength was 88% (SD 9.4) in Group A and 87% (SD 7.7) in Group B. In conclusion, fixation of basal ulnar styloid fractures is not mandatory if the DRUJ is stable after rigid fixation of the associated fracture of the distal radius. Level of evidence: II
