Evaluation of Outcomes of Surgical Treatment for Nonspecific Infectious Spondylodiscitis Via Posterior Approach in One Center.

The Use of Posterior Approach for Surgical Treatment of Nonspecific Spondylodiscitis.

Non-specific spondylodiscitis is a bacterial infection of the spine that in some cases requires surgical treatment. The basis of surgical treatment is the removal of affected tissues. In this case, the supportive function of the affected area is lost, which also requires stable fixation. Access to the affected part of the spine can be achieved through both anterior and posterior approaches. There is no reliable data yet confirming the advantages of each approach. Our study demonstrated successful surgical treatment of infection foci using posterior approach, no neurological or other complications were occurred. Older patients shown differences in hemoglobin levels, postoperative pain scores, the number of affected vertebrae, types of bacteria and recurrent rate.

This retrospective study was conducted on 38 patients with spondylodiscitis treated using a posterior approach. Clinical data were evaluated in four age groups: under 39 years, 40-49 years, and 50-59 years and over 60.
