Bone tuberculosis, in patients with no prior history of tuberculosis

There are different types of infection caused by Mycobacterium tuberculosis, the pulmonary variety is the most common of them; infection of the bone secondary to joint replacement, is usually caused by a previous lung infection that has been disseminated. However primary bone infection is very rare and little reported, which makes information on the matter very scarce. A female patient is presented with a history of congenital hip dysplasia, who underwent multiple surgical interventions, including total hip arthroplasty (THA), afterwards she presented a fistula and persistent serous exudate; a biopsy was performed where acid-fast bacilli were detected. The delay in the diagnosis of osteoarticular tuberculosis (OATB) can lead to negative consequences, affecting the quality of life of the patient. Conventional diagnostic methods may be insufficient for the diagnosis of OATB.
