OBJECTIVE: We propose a revised flow chart of spinal infection multidisciplinary management project (SIMP) aimed to standardize the diagnostic process and management of spinal tuberculosis (TB).

MATERIALS AND METHODS: We reviewed data from all TB cases with osteoarticular involvement treated at a large tertiary teaching hospital in Bologna, Northern Italy, from January 2013 to December 2017. We cross-linked notified osteoarticular TB cases with SIMP database and we analysed clinical, diagnostic, and treatment data of all cases managed by SIMP.

RESULTS: Osteoarticular TB accounted for the 7.8% (n=40) of all TB cases notified between 2013 and 2017 (N=513). Among the identified cases, 52% (n=21/40) had spine involvement: all were enrolled and evaluated by SIMP multidisciplinary group. Females accounted for 57% (12/21) of patients, the median age was 52 years (range 24-82). In the 67% (n=14/21) of cases, the major clinical symptom of spinal TB was back pain reported for a median of 4.5 months (range 1-12 months) before hospital admission. The interferon gamma release assay was positive in 75% (n=16/21) of patients. All patients performed MRI with gadolinium, which indicated spondylodiscitis in 90%. 18F-FDG-PET/CT revealed average maximum standardized uptake value (SUV max) of 12.54 (range 5.3-22) in 17/19 (89.5%). Bacteriological confirmation of TB was obtained in 86% of cases (n=18/21). One-third of patients (7/21) underwent surgery and 95% successfully completed the anti-TB treatment.

CONCLUSIONS: Our data reveal that a multidisciplinary approach to spine tuberculosis facilitates early and accurate diagnosis and can improve medical and surgical management of this disease.
