Spondylodiscitis is a common but potentially serious form of extra-pulmonary tuberculosis. Very few descriptions are known from Tunisia. We have conducted a retrospective study including 60 cases of spinal tuberculosis, performed over a period of 20 years (1996-2016). The diagnosis was retained on bacteriological, radiological and anatomopathologic evidence. Sixty cases including 31 women and 29 men of spinal tuberculosis were involved. The mean age was 54.4 ± 21.3 years. The delay from onset to diagnosis was 6 months (1-14). Lumbar region was the most common infection site (68%). The magnetic resonance imaging has confirmed spinal infection in all cases. The percutaneous image guided spinal biopsy was conclusive in 24/42 cases (57.1%). All patients were put under anti-tuberculosis treatment with total treatment duration of 14 months. Fourteen patients underwent surgical act. The outcome was favorable in 42 cases (7%). Advanced age ≥ 65 years ( = 0.026), radiological evidence of spinal cord compression ( = 0.033) or abscess ( = 0.024), hyperleucocytosis higher than 11,500 elements/mm (0.031), or fractures on bone imaging ( = 0.018) and vertebral deformity ( < 0.001) were strongly linked to a bad outcome. Early diagnosis and treatment onset may ensure better outcomes and reduce neurological complications and vertebral deformity.
