Radiocarpal dislocation is an uncommon injury that is usually caused by high-energy trauma. Herein, we present two cases of dorsal radiocarpal dislocation with radial styloid fractures that were treated by arthroscopy-assisted reduction and internal fixation. Wrist arthroscopy provides accurate information on intra-articular fractures and carpal and/or intracarpal ligamentous tears of the radiocarpal joint. Furthermore, the procedure enables simultaneous anatomical reduction of intra-articular fractures and radiocarpal and/or intercarpal ligament repair. Arthroscopy-assisted reduction and internal fixation yield satisfactory outcomes for patients presenting with dorsal radiocarpal dislocation and radial styloid fractures.
