Résumé
The displaced thalamic calcaneal fractures involve the functional prognosis of the ankle and foot. The purpose of our study is to defend the surgical treatment of these fractures. We report a continuous and retrospective serie of 42 displaced and isolated fractures treated by open reduction bone graft and osteosynthesis by little plate In a more 3 years review based on SOFCOT criteria functional results are considered excellent and good for 69 per cent of the cases We had restored and maintained the Boehler Angle for 90%of fractures with a no significatively mean loss of 4.33°, Astragalo thalamic congruency is good for 85%of cases. Late complications were dominated by arthrosis of the ankle [12%]. For the indications, we believe that all displaced thalamic fractures of the calcaneum must be operated whatever the radiologic stage. The only contra-indications that must be discussed are the old age, the skin status and arterial pathology
