Bone tuberculosis

Bone tuberculosis is mostly secondary to tuberculosis. However, some patients have no history of tuberculosis, which is an occult infection of tuberculosis bacteria. Most of the tuberculosis sclerotia occur first in the lungs. After the infection of the lungs, blood can spread to many systems throughout the body, which can lead to skeletal system tuberculosis, urinary system tuberculosis, and digestive system tuberculosis. Therefore, bone tuberculosis is not a simple disease, but a local manifestation of systemic disease.
