BackgroundSpontaneous non-specific pyogenic spondylodiscitis (SNPS) is a rare medical condition, whose optimal treatment remains controversial. We evaluated the multidisciplinary protocol implemented at our department for the conservative treatment of patients with SNPS.MethodsPatients with lumbar or thoracic SNPS, whose treatment was initiated conservatively and had at least six months of follow-up, were enrolled in this retrospective audit study. Patients with specific, postoperative, or iatrogenic spondylodiscitis or necessitating immediate operative treatment were excluded. The location of the infection, initial symptoms, co-morbidities, pathogens, duration of antibiotic treatment, hospitalization and follow-up, and outcome were retrieved. The visual analogue scale (VAS) score was used to register pain improvement after treatment.ResultsBetween January 2011 and December 2021, forty-seven patients (male: 26, mean age: 68.5 years) with SNPS (lumbar: 29, thoracic: 18) were hospitalized. The main co-morbidity was diabetes mellitus (23 patients). Pain was the predominant (46 patients), and fever was the second most common (19 patients) symptom. The most frequent causative microorganism was staphylococcus aureus (29 patients); no pathogen was identified in ten patients. The mean hospitalization duration for patients completing their conservative treatment (43/47) was 27 (range: 22-41) days. They received antibiotics for a mean period of 23 days intravenously (range: 21-29), 23.8 days per os (range: 21-35), and 46.8 days in total (range: 42-63). Conservative treatment was discontinued in two females. Two male patients died due to septic shock. The mean follow-up was 11.5 months (range: 6-15). During follow-up, no one developed any neurologic deficit and/or recurrence. There was a significant improvement in the mean VAS, from 8.3 ± 0.8 pre-treatment to 1.6 ± 0.5 at the latest follow-up (p <0.001).ConclusionsAlthough treatment is gradually shifting towards surgical intervention, conservative therapeutic management of SNPS patients with antibiotic administration, bed rest, and careful mobilization remains a viable and efficacious option.
