Answer

Between 2002 and 2011, a total of 75,858 cases of TB were reported in the United States. Of these, 2,789 cases (3.7%) involved the spine. The median age among affected individuals was 51 years; 61% of cases involved males, and 11% had diabetes mellitus. Twenty percent required surgery, most commonly of the thoracic-lumbar segments. [9]

Although the incidence of tuberculosis increased in the late 1980s to early 1990s, the total number of cases has decreased in recent years. The frequency of extrapulmonary tuberculosis has remained stable. Bone and soft-tissue tuberculosis accounts for approximately 10-15% of extrapulmonary tuberculosis cases and between 1% and 2% of total cases. Tuberculous spondylitis is the most common manifestation of musculoskeletal tuberculosis, accounting for approximately 40-50% of cases. These figures are roughly similar for North American and international series. [10, 11]
