Abstract

Distal radioulnar dislocation is commonly associated with radius fracture. Most common dislocation pattern is the dorsal dislocation. We present the unique case of volar dislocation of the distal radioulnar joint blocked by displaced dorsal Barton fracture of distal radius and discuss the injury mechanism and anatomic lesions.

Keywords: Distal radioulnar joint, Dorsal Barton fracture, Distal radius fracture, Galeazzi fracture

Preoperative plain radiographs of left wrist. (A) Anteroposterior and lateral radiographs show displaced dorsal Barton and ulnar styloid process fracture with volar dislocation of the distal radioulnar joint (DRUJ). (B) Computed tomography axial view shows that the size of the displaced bone fragment have involved an area ≥1/2 of the sigmoid notch and the fragment is trans-positioned ulnarly to the DRUJ.

Fig. 2.

Intraoperative photographs, (A) shows ulnarly displaced dorsal Barton fracture. (B) Open reduction and internal fixation were conducted through a dorsal approach.

Fig. 3.

Postoperative anteroposterior and lateral radiographs show internal fixation of dorsal Barton fracture and tension band wiring of unlar styloid process fracture maintaining distal radioulnar joint reduction in anatomic alignment.
