Purpose: The purpose of this study is to assess the effi cacy of posterior decompression and interbody fusion with posterior instrumen tation in treating lumbar pyogenic spondylitis.
Materials and Methods: Twenty-one patients with lumbar pyogenic spondylitis who underwent posterior decompression and lumbar interbody fusion with posterior fi xation were reviewed. Clinically infection control (CRP normalization time) and rehabilitation were investigated. And radiologically, timing of achievement of fusion and changes of sagittal alignment were investigated.
Results: Infection was controlled successfully without any recurrence and breakage of instrument. Stable interbody fusion was achieved in all cases within 6 months. Postoperative interval to achieve normal CRP was 28.7 (10-64) days. Ambulation was started on 5.8th (2-19) day. Sagittal angle was 12.3 degrees before operation, became more lordotic to 16.4 degrees, but decreased to 11 degrees at fi nal follow-up. Final sagittal alignment was almost same with the preoperative status.
Conclusion: By achieving favorable results clinically and radiologically, posterior decompression and interbody fusion seemed to be an effective method in management of lumbar pyogenic spondylitis.
