Introduction Bone tuberculosis, also known as skeletal tuberculosis or osteoarticular tuberculosis, is a chronic infectious disease caused by the bacterium Mycobacterium tuberculosis. While pulmonary tuberculosis is more common, bone tuberculosis affects a small percentage of individuals with TB. This article aims to shed light on how bone TB spreads, its causes, and methods of prevention.
