Study Design: A retrospective study on the outcomes of surgical treatment for pyogenic lumbar spondylodiscitis.
Objectives: To report the clinical outcomes of the surgical treatment of pyogenic lumbar spondylodiscitis using a one stage posterior approach.
Summary of Literature Review: There are few reports on the treatment of pyogenic lumbar spondylodiscitis through a one stage posterior approach.
Materials and Methods: Between June 1999 and June 2005, this study examined the history of 12 patients with pyogenic lumbar spondylodiscitis treated by simultaneous posterior debridement, autogenous iliac bone graft and pedicle screw fixation. The clinical outcomes were evaluated in terms of the pain level, neurological status, hematological parameters and radiology findings.
Results: The clinical symptoms improved in all cases after surgery. There was no case of the infection recurring. The mean time for postoperative antibiotics and hospitalization was 6 weeks and 41.6 days, respectively. Radiological bony fusion was observed at 5.5 months on average. The mean preoperative, immediate postoperative and final follow-up sagittal angles were 4.6, 8.6 and 6.9°.
Conclusion: One stage posterior interbody fusion and instrumentation for the treatment of pyogenic lumbar spondylodiscitis can provide radical debridement, bone graft and immediate stability without prohibiting the control of infection. Therefore, it can be used in selected cases.
