A 20-year-old man involved in a fall developed AO/OTA C3 pilon fracture. A) Preoperative transverse computed tomography (CT) scans showed severe fracture displacement of the distal tibial articular surface. B & C) The anteroposterior and lateral view of the ankle showed that external fixation was used to maintain the length and axial alignment of the limb after undergoing external fixation in the first stage for 19 days. D & E) The lateral view showed good reduction and fixation after undergoing open reduction and internal fixation through the simple anterior approach in the delayed procedure. F) Postoperative transverse CT scans showed articular surface step-off of more than 5 mm
