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.
