Bone tuberculosis (TB) is relatively uncommon form of extrapulmonary TB in children. It is estimated that 1-6 % children with primary infection may develop bone and joint TB in 1-3 years if left untreated. Though short course chemotherapy has been found to be effective in treating bone and joint TB, due to emergence of multi drug resistant (MDR) TB, the incidence of resistant bone TB is also rising. Here we have 5 cases of bone TB affecting different sites and having a broad spectrum of antitubercular drug sensitivity pattern ranging from drug sensitive bone TB to MDR bone TB.
