Objective: To investigate the effect of medical ozone in treatment of failed back surgery syndrome (FBSS) through percutaneous puncture injection. Methods: Under digital subtraction angiography fluoroscopic guidance,24 FBSS patients were injected 20 ml medical ozone (45 μg/ml) through percutaneous puncture in inter-vertebral disc and paravertebral space. The relief of clinical symptoms was also observed. Results: After 2 to 57 months of follow-up in the 24 patients,the total effective rate was 62.5%,including 8 significant effective cases and 7 improved cases. Except for 1 case with cough and chest tightness, the other patients had no complications. Conclusions: Medical ozone is effective for FBSS treatment through percutaneous puncture injection.
