A preoperative radiograph shows a trimalleolar fracture with fibular comminution (a). A postoperative radiograph shows restoration of the length and radiologic parameters. Talocrural angle (α) was defined as the angle between the distal tibial articular line and the line connecting the tips of the distal fibula and medial malleolus. Fibular length (β) was defined as the distance from the distal fibular tip to the distal tibial articular line (b). One-year follow-up radiograph shows good union (c)
