Abstract

Objective: To evaluate changes in the Oswestry Disability Index (ODI) and modified Macnab scores after treating lumbar disc herniation with percutaneous ozone therapy under computed tomography (CT) guidance at Xanh Pon General Hospital. Method: A prospective interventional study was conducted on 100 patients in the intervention group and 47 patients in the control group. Ozone therapy was combined with percutaneous corticosteroid injection under CT guidance. Results: The treatment effectiveness was demonstrated by the following indicators: Improved spinal function: The ODI score significantly decreased from 70.6% before treatment to 27.5% after 6 months. Macnab classification after 6 months: Outcomes were rated as very good (41%), good (38%), moderate (7%), and poor (14%). Short-term and mid-term treatment outcomes at 1 and 3 months showed no significant differences between the study and control groups. After 6 months, the study group experienced significantly lower pain levels and less functional impairment compared to the control group. Conclusion: Percutaneous ozone therapy demonstrated superior efficacy in improving spinal function, as evidenced by a significant reduction in the ODI score after 6 months. Compared to the control group, the study group had lower pain levels and reduced functional impairment at long-term follow-up.
