Ankle tuberculosis

Ankle tuberculosis accounts for 3.4% of systemic bone tuberculosis, with the lowest incidence among the three major joints of the lower limbs. Ankle joint synovial tuberculosis is more common, and it is more likely to be transformed into total joint tuberculosis than bone tuberculosis, especially talar tuberculosis and lower tibial tuberculosis. There is less soft tissue around the ankle joint. Ankle abscesses can easily penetrate the skin and form sinus tracts, with the most anterior and lateral sides. Late foot drop and varus deformity are visible.
