Ankle fractures and associated ligamentous injuries are the most common injuries of a load-bearing joint. There is still no general consensus with respect to the pathomechanism, the treatment indications and surgical techniques. The medium and long-term results are affected by a particularly high risk of posttraumatic arthritis in bimalleolar and trimalleolar fractures and fracture dislocations. There is consensus on the necessity of a thorough preoperative analysis and postoperative control of reduction for which 3D imaging is increasingly generously employed. This detects relevant pathologies, such as bony syndesmotic avulsion and partial impaction of the tibial plafond that may go unnoticed on plain radiographs. Anatomic reconstruction of the ankle mortise, the detection and treatment of syndesmotic instability, reconstruction of the tibial notch and exact placement of the distal fibula into the latter are important prognostic factors.
