Introduction Established treatment options of spondylodiscitis, a rare but serious infection of the spine, are immobilization and systemic antibiosis. However, the available data for specific treatment recommendations are very heterogeneous. Our intention was to develop a classification of the severity of spondylodiscitis with appropriate treatment recommendations. Materials and methods From 10/1/1998 until 12/31/2004, 37 cases of spondylodiscitis were examined regarding medical history, gender status, location and extent of spondylodiscitis, type and number of operations. Subsequently, a classification of six grades according to severity has been developed with specific treatment recommendations. The further evaluation of our classification and corresponding treatment modalities from 1/1/2005 to 12/31/2009 including further 132 cases, resulted in a classification of only three grades of severity (the SSC—spondylodiscitis severity code), with a follow-up until 12/31/2011. Between 01/01/2012 and 12/31/2013, a prospective study of 42 cases was carried out. Overall, 296 cases were included in the study. 26 conservatively treated cases were excluded. Results and Conclusion The main localization of spondylodiscitis was the lumbar spine (55 %) followed by the thoracic spine (34 %). The classification of patients into 3 grades of severity depends on clinical and laboratory parameters, the morphological vertebral destruction seen in radiological examinations and the current neurological status. Therapies are adapted according to severity and they include a specific surgical management, systemic antibiotic therapy according to culture and sensitivity tests, physiotherapy and initiation of post-hospital follow-up. 40.6 % of patients are associated with neurological deficits, classified as severity grade 3 and treated surgically with spinal stabilization and decompression. 46.9 % of patients corresponded to severity grade 2, with concomitant vertebral destruction were dorsoventrally stabilized. The 31 patients of severity Grade 1 were treated surgically with dorsal stabilization. From 1998 to 2013, the time from the onset of symptoms to the first surgical treatment was about 69.4 days and has not changed significantly. However, the time from admission to surgical treatment had been reduced to less than 2 days. Also the time of hospitalization was reduced and we see positive effects regarding the sensation of pain. 270 patients underwent surgery. We treated 89 % dorsa
