Weight-bearing joints are most commonly involved, but bones of the wrist, hand, and elbow may also be affected, especially after injury. As with the other forms of extrapulmonary TB, TB bacilli must then be extracted from the affected bone or joint using a needle syringe to extract a small sample. Pericardial infection may develop from foci in mediastinal lymph nodes or from pleural TB. Meningitis often occurs in the absence of infection at other extrapulmonary sites.
