Objective:In this study, the evaluation of the clinical, laboratory and radiological findings belonging to 55 cases that were hospitalized in our clinic to be followed-up and were diagnosed with tuberculous, brucellar and pyogenic spondylodiscitis (SD) was aimed.Materials and Methods:The cases with SD were evaluated retrospectively. Hematological, serological, biochemical laboratory tests and imaging technics were used for diagnosis.Results:Of 55 cases aged ranging between 25 to 79, 33 (59%) were female. The cases with tuberculous SD (TBSD), brucellar SD (BSD) and pyogenic SD (PSD) were found in 24 (43%), 12 (21%) and in 19 (34%) patients. Erytrocyte sedimentation rate, increased C-reactive protein, and leucocytosis were present in 51 (91%), 22 (39%) and 8 (14%) cases. The number of the cases with history of previous surgery or trauma was 14 (25%). Diagnosis of TBSD was established by acid fast bacilli positiveness and Löwenstein Jensen culture positiveness, in two and seven patients, respectively. While all 12 cases with BSD had positive standard tube aglutination test, only 3 (25%) had hemoculture positivity. In PSDs, diagnosis was confirmed with culture positivity in 9 of 19 cases.Of the cases in our study, 89% responded to medical treatment while three required surgery and three died (5.5% and 5.5%, respectively).Conclusion:SD may develop secondary to infections or following spinal surgical procedures and traumas. Also, the importance of endemicity should be kept in mind, beside the helpful diagnostic findings while treatment regulation.
