Distal Radioulnar Joint Dislocation Following Radius Bridging Plate for DRF

Abstract

Background

This case report highlights two cases of progressive distal radioulnar joint dislocation following dorsal bridging plate (DBP) fixation for complex distal radius fractures (DRFs), a complication not previously documented in this situation.

Case Description

Both cases involved young patients with associated non-displaced basal ulnar styloid fractures, treated using DBP without addressing ulnar-sided lesions. Postoperative CT scan analysis revealed anterior translation of the distal radius metaphysis.

Literature Review/Clinical Relevance

The non-anatomic straight design of the plate, when associated with a destabilizing ulnar-sided lesion, may contribute to this complication by moving anteriorly the distal metaphysis of the radius. Further research is necessary to establish a causal relationship between the implant design and anterior translation of the distal radius metaphysis. In cases involving a combination of ulnar-sided wrist injuries and DBP management for DRF, it is advisable to address ulnar-sided wrist injuries during the initial management of DRF when using DBP.
