Isolated Tuberculous Osteomyelitis of Calcaneus in an Immune-Competent Adult Patient With Literature Review

CASE: We present a case of isolated tuberculous osteomyelitis of the calcaneus in an immune-competent adult patient with a 5-year follow-up. The diagnosis was established by core needle aspiration and biopsy. He was treated with antituberculous chemotherapy and immobilization. The lesion healed with collapse of the calcaneal tuberosity that clinically resulted in shortening and heel valgus. A literature review is also presented. CONCLUSION: Isolated tuberculous osteomyelitis of the calcaneus in an immune-competent adult patient is rare. It may pose diagnostic dilemma, and orthopaedist should work through the differential diagnosis.
