• 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.
