Single-stage Anterior Debridement and Fusion with Autografting and Internal Fixation for Pyogenic Lumbar Spondylodiscitis

Introduction: Patients with pyogenic lumbar spondylodiscitis can be successfully treated by non-operative methods. However, the typical operation for this condition includes debridement of the infected site, bone grafting and internal fixation to stabilize the spine. Single-stage anterior debridement and fusion with autografting and internal fixation of one spinal segment were performed on nine patients with pyogenic lumbar spondylodiscitis. This operative procedure is rarely documented for pyogenic lumbar spondylodiscitis.

Aim: To evaluate the safety and effectiveness of single-stage anterior debridement, autografting and internal fixation of one spinal segment for pyogenic lumbar spondylodiscitis.

Results: At the final follow-up, seven out of the nine patients were pain free. Two patients had mild, intermittent back pain (Visual Analogue Scale rating of 1-2), which represented an improvement from their preoperative pain. All nine patients had no clinical, laboratory or radiological evidence of recurrence of infection. Moreover, all the patients showed solid bony fusion.

Conclusion: Based on the limited population studied, it suggested that this technique may be a safe and effective operative procedure for appropriate pyogenic lumbar spondylodiscitis in patients.
