Abstract

Background: Ulnar styloid fractures are frequently associated with distal radius fractures; however, their optimal management remains controversial. In particular, the necessity of fixation in relation to distal radioulnar joint (DRUJ) stability continues to be debated.

Case Report: This article presents three representative clinical scenarios alongside a focused review of the current literature regarding ulnar styloid fracture management. The discussion emphasizes intraoperative assessment of DRUJ stability and its role in guiding treatment decisions. Conservative management is generally appropriate for minimally displaced or tip fractures, whereas selective fixation may be considered in displaced basal fractures associated with DRUJ instability.

Conclusion: Management of ulnar styloid fractures should be individualized based on DRUJ stability rather than fracture union alone. Selective fixation in cases of true instability yields favorable outcomes, while routine fixation is not recommended. Nonunion of the ulnar styloid is often clinically insignificant, and avoidance of unnecessary surgical intervention may reduce complication rates
