Astragalus Tuberculosis: A Case Report and Review of the Literature.

Osteo-articular tuberculosis continues to be a major global pandemic, with its greatest impact in the third-world countries. Among osteo-articular tuberculosis, plantar localisation, particularly isolated involvement of the talus is an extremely rare event. We discuss the case of a 20-year-old male diagnosed with isolated tuberculosis of right talus without the radiological involvement of the distal tibia, fibula or calcaneum. The diagnosis was made with the help of magnetic resonance imaging and confirmed through core biopsy of the talus. He was treated with multi-drug antitubercular chemotherapy and ankle immobilization with protected weight bearing with good results.
