Treatment with or without internal fixation for ulnar styloid base fractures accompanied by distal radius fractures fixed with volar locking plate.

The purpose of this study was to evaluate the treatment results, with and without internal fixation of ulnar styloid base fractures associated with acute distal radius fractures. A total of 48 patients were enrolled, including 20 patients treated by internal fixation (fixation group) and 28 treated without internal fixation (non-fixation group). The evaluated parameters were postoperative range of motion, grip strength, DASH score, and the presence or absence of ulnar wrist pain over time. The outcome was assessed as "excellent" in 15 patients of the fixation group and 21 patients of the non-fixation group, and "good" in five patients of the fixation group and seven patients of the non-fixation group. There were no significant differences in the clinical outcomes or any of the parameters at the final evaluation between the two groups. However, the grip strength was significantly better in the non-fixation group than in the fixation group until 12 weeks postoperatively. The overall clinical outcome was good in both groups, with no significant difference between the groups.
