Häufig übersehene peritalare Frakturen

Peripheral talus fractures are among the rarest foot injuries (20% of all talus fractures). These fracture can lead to a reduced functional outcome and are associated with concomitant injuries such as subtalar dislocation. Furthermore, peripheral talus fractures are often diagnosed late or even overlooked, suggest ing a high number of unreported cases. This can be explained by the poor visibility of the fractures on conventional x -rays. If such x-rays do not indicate a fracture but the clinical picture does, further clarification with cross-sectional imaging, in particular computerised tomography, should be considered.

Peritalar fractures can be categorised according to the American Orthopaedic Trauma Association (OTA) or the AO classification. In contrast, fractures of the lateral talar process are categorised according to Hawkins. Subtalar dislocations are categorised according to their dislocation pattern. Depending on the fracture morphology, soft tissue damage and concomitant injuries, the further procedure (conservative or surgical treatment) is determined. The few existing studies show that the severity of the injury and the concomitant injuries have an influence on the outcome.
