case_images: Plain radiographs of the right ankle showed no abnormal findings in anteroposterior and lateral views (Figure 1).
case_images: Preoperative noncontrast CT in (a) sagittal and (b) axial views demonstrated the fracture line from the lateral side of the posterior lateral process to the posteromedial side of the talus body. In addition, the fracture line extended to the posterior ankle and subtalar joints, and the bone fragment was slightly displaced.

case_images: In addition, the fracture line extended to the posterior ankle and subtalar joints, and the bone fragment was slightly displaced (Figure 2).
case_images: After the posterior aspect of the talus was observed using a 4.0-mm-diameter 30  arthroscope, and soft tissues around the talus including synovium, adipose tissue, and coagulation clot were removed with a 4.0-mm-diameter motorized shaver, the fracture site was confirmed (a). The fragment was reduced using a guidewire sleeve and fixed with two 0.8 mm guidewires from posteromedial portal (b). Through the guidewires (c), the fragment was fixed with two cannulated double-threaded screws (d).
