Medium-term outcome of posterior surgery in the treatment of non-tuberculous bacterial spinal infection

Objective: to evaluate the outcome of posterior spinal stabilization surgery for the management of bacterial spinal infection.

Methods: 21 patients with bacterial infection were managed surgically with posterior stabilization. Outcome measures included neurological status. Follow-up data collected using Spine Tango COMI questionnaires and Euro Qol EQ-5D.

Results: The mean improvement in neurological deficits was 0.91 Frankel grade. Residual symptoms of pain had no or minor effect on the work or usual activities in 52% of subjects, with 88% reported having either no or mid problems with mobility.

Conclusion: Posterior surgery can improve neurological outcome in approximately half of the patients.
