Spinal tuberculosis revisited.

Although the incidence of tuberculosis is decreasing, spinal tuberculosis is still an important disease. Delay in diagnosis and treatment results in long-term disability. We reviewed our cases of spinal tuberculosis diagnosed between 1975 and 1982, with special reference to those features that permit early diagnosis. Among the nine cases diagnosed, roentgenographic evidence of pulmonary tuberculosis (7/9) and positive PPD test (8/8) were found to be highly suggestive diagnostic clues. Computerized tomography (CT) of the spine was a useful way of determining the extent of the disease and following response to therapy. Various modes of therapy were used, and the outcome was related to the extent of the disease and duration of symptoms before initiation of therapy. In early stages, medical therapy alone is adequate; surgical intervention is necessary in cases with neurologic features.
