[Pilon fractures : Review of diagnostics and classification].

Intraarticular fractures of the distal tibia (pilon fractures) are rare injuries and today they occur mostly in traffic accidents and falls from a great height. There are simple fractures in the context of low-energy traumas, as well as complex comminuted fractures in high-energy traumas. Besides the clinical examination, plain radiographs and computed tomographic scans are diagnostic prerequisites. The aim of the diagnostic process is to clearly identify and classify the fracture before appropriate treatment is initiated. The systems used to classify the displaced distal pilon fractures are supposed to ensure the three-dimensional assessment of the fracture and provide high inter- and intra-observer agreement. In addition to the classification of Rüedi and Allgöwer, the classification of pilon fractures has been carried out using the AO classification.
