Ulnar Styloid Fracture Fixation
We are unable to recommend for or against fixation of ulnar styloid fractures associated with distal radius fractures.

Rationale
Ulnar styloid fractures are relatively common in association with distal radius fractures.  We were interested in the effect of concomitant fixation of the styloid on patient outcome.  One study found no difference between treatment (fixation) and no treatment.92  The other study identified ulna styloid fractures after treatment was completed and the study found that there were clinically important differences between patients with and without styloid fractures.93 Therefore no ulna styloid fractures were treated at the time of surgery. Although the patients with ulna styloid fractures had poorer outcomes, the study did not address the question of whether early operative intervention is indicated. Therefore, we found no conclusive evidence to recommend operative or non operative treatment for the ulna styloid fracture.
