Abstract

Dorsal perilunar dislocations are rare traumatic entities. Associated fractures such as carpal bones and radial styloid processes can occur. However, the dorsal perilunar dislocation associated with dislocation of distal radioulnar joint is extremely rare. The authors herein report the case of a 34-year-old man who was presented with transscaphoidal perilunar dislocation which is associated with dislocation of distal radioulnar joint.

Figure

• 

  Fig. 1 (A) Plain radiographs at initial trauma show the transscaphoidal dorsal perilunar dislocation associated with dislocation of distal radioulnar joint. (B) Contralateral radiographs.

• 

  Fig. 2 Plain radiographs and computed tomography after closed reduction show a comminuted fracture at waist and distal portion of the scaphoid.

• 

  Fig. 3 Postoperative radiographs show open reductions and internal fixations when using K-wires for the scaphoid fracture and percutaneous K-wire transfixation for the dislocation of distal radioulnar joint.

• 

  Fig. 4 Radiographs at 15 months after surgery show bony unions without carpal instability.

• 

  Fig. 5 Photographs at 15 months after surgery show normal range of motion.
