Abstract

Background

Due to the aging society, the incidence of pyogenic spondylodiscitis is still rising. Although surgical treatment for spondylodiscitis in general is increasingly accepted, an optimal surgical strategy for treatment of pyogenic spinal infection has not yet been established. The aim of this study was to investigate the suitability of percutaneous posterior pedicle screw fixation for surgical treatment in patients with spondylodiscitis of the thoracolumbar spine.

Methods

We conducted a retrospective review of a consecutive cohort of patients undergoing surgical treatment for spondylodiscitis of the thoracolumbar spine between January 2017 and December 2019. We assessed intraoperative and clinical data, comparing for the classic open and the percutaneous approach. In total, we analyzed 125 cases (39 female, 86 male). The mean age was 69.49 years ± 12.63 years.

Results

Forty-seven (37.6%) patients were operated on by a percutaneous approach for pedicle screw fixation, and 78 (62.4%) received open surgery. There was no significant difference in the mean age of patients between both groups (p= 0.57). The time of surgery for percutaneous fixation was statistically significantly shorter (p= 0.03). Furthermore, the estimated intraoperative blood loss was significantly lower in the minimally invasive group (p < 0.001). No significant difference could be observed regarding the recurrence rate of spondylodiscitis and the occurrence of surgical site infections (p= 0.2 and 0.5, respectively).

Conclusion

Percutaneous posterior pedicle screw fixation appears to be a feasible option for the surgical treatment of a selected patient group with spondylodiscitis of the thoracic and lumbar spine.
