The purpose of this study was to compare outcome for treatment with Ozone intradiscal combined steroid and transforaminal corticoid injection under CT guidance for the treatment of lumbar disc herniation. This was a prospective study, 147 patients symtomatic with lumbar disc herniation were divided into 2 groups: 100 patients treated with Ozone injection combined with steroid, and 47 patients (control group) treated with to transforaminal corticoid injection. After 1 month, 3 months of treatment, the VAS, ODI% scores of both groups decreased significantly compared to before treatment (p < 0.05) but there was no difference between the two groups (p>0.05). Up to 6 months post treatment, the patients in the study group had significantly lower VAS, ODI% scores compared to the control group (p < 0.05). The disc volume of the study group decreased significantly after treatment (p < 0.05). As such, Ozone therapy is highly effective in the treatment herniated disc which is equivalent to transforaminal corticoid injection at the time of short-term and medium-term follow-up. At the time of long-term follow-up, Ozone therapy is more effective than transforaminal corticoid injection.
