Hydatid disease of bone is very rare and is often misdiagnosed because of non-specific presentation and radiology. As its management is quite different from other conditions involving the bone, it is important to consider the differential of Hydatid disease of the bone in lucent bone lesions, especially where the echinococcosis is prevalent. Hydatid Disease or […]

Tuberculosis of foot is rare and constitutes less than 10% of cases of osteoarticular tuberculosis. Calcaneum is the most common bone involved followed by subtalar joint and midtarsal joints. Pathophysiology Bonewise, the order of involvement in decreasing order is calcaneum, talus, first metatarsal, navicular, first and second cuneiforms cuboid and others. The infection first lodges […]

Tuberculosis of ankle joint is relatively uncommon. The incidence of ankle tuberculosis is less than 5 percent of all osteoarticular tuberculosis. Pathophysiology The mycobacteriaereachs the ankle joint viathe bloodstream. The initial focus may start in the synovium, especially in children, or as an erosion in the distal end of tibia, malleoli or talus. Rarely tuberculosis […]
