Tuberculosis of Talonavicular Joint Without Pulmonary Involvement in an Indian Child: A Report of a Rare Case

Osteoarticular tuberculosis is a rare entity, even in endemic countries. Isolated cases of tuberculosis of the talonavicular joint are sparse. Primary involvement of the talonavicular joint without pulmonary infection with Mycobacterium tuberculosis is rarest of rare. Here, we report a case of primary talonavicular joint tuberculosis without pulmonary involvement in an Indian child. To the best knowledge of the authors, it is the third such case ever reported in a child in the world. The patient presented with complaints of pain and swelling of the right foot. Detailed laboratory work-up backed by radiological investigations helped in establishing the diagnosis. He was managed conservatively with antitubercular chemotherapy with improvement in his symptoms and was transferred out to his native village.
