Relapse of bone tuberculosis is usually not easy after complete cure. The recurrence of bone TB may be due to the fact that the last treatment was not completely cured and the TB bacilli in the body were only temporarily suppressed. In that case, if the patient’s immunity is low, the TB bacilli may be reactivated and may cause the recurrence of bone TB. In addition, it is also possible that the patient, with low immunity, may be reinfected with Mycobacterium tuberculosis and cause the disease to develop. Therefore, it is very important for TB patients to have their immune system strengthened. Whether recurrence of bone tuberculosis after surgical treatment depends on many factors, the specific factors are as follows: 1. the patient’s physical condition: for example, some patients may have symptoms such as anemia and wasting after a long period of tuberculosis; 2. the patient must undergo regular anti-tuberculosis treatment before surgery, which requires at least half a month of treatment; 3. related to the surgeon’s skill and experience, such as whether the surgeon clears the lesion; 4. the patient after surgery The patient must also undergo regular anti-tuberculosis treatment, and the duration of anti-tuberculosis treatment should be long enough, generally the standard course of anti-tuberculosis treatment is one and a half years; 5. Nutritional support treatment: patients treated with anti-tuberculosis must be given enough protein. Bone tuberculosis is a curable disease, and the principles of anti-tuberculosis treatment must be observed, i.e. early, regular, full course, combined and appropriate amount.
