MATERIAL and METHODS: Data of patients who underwent debridement or stabilization surgery for thoracolumbar pyogenic spondylodiscitis from January 2012 to December 2018 were reviewed. Lumbar and thoracolumbar spondylodiscitis was classified into four stages based on anatomical involvement. Infection was limited in the disc space, which had not spread to the endplate in stage 1 and progressed as two-level corpus involvement of >1/2 of vertebral corpus bony destruction or as failed treatment in stage 4. Neurological function was evaluated using Frankel's grading postoperatively. Functional outcomes were categorized according to the Kirkaldy-Willis criteria.

RESULTS: The study included 39 patients, with a mean age of 58.2 years. Of these patients, 10, 12, 13, and 4 had stages 1, 2, 3, and 4 spondylodiscitis, respectively. The mean follow-up period was 60.2 (12-184) months. All patients with stages 1 and 2 spondylodiscitis had grade E injury; 2 and 10 patients with stage 3 had grades D and E injuries, respectively; two patients with stage 4 had grade D injury and two had grade E injury at the last follow-up. Moreover, 100%, 84.6%, and 50% of the patients with stages 1 and 2, 3, and 4 spondylodiscitis achieved good or excellent results, respectively.

CONCLUSION: The choice of the surgical technique depends on the destruction severity at the adjacent vertebral corpus. Surgical staging system for spondylodiscitis is useful and reliable in choosing appropriate surgical techniques.
