Abstract
Objective To observe the effects and safety of CT-guided radiofrequency thennocoagulation combined with ozone nucleus pulposus ablation in treatment of lumbar disc hemiation. Methods Eighty cases with lumbar disc hemia-tion were randomly divided into ozone treatment group ( 40 cases ) and combination treatment group ( 40 cases ). The cases in the ozone group were treated with ozone nucleus pulposus ablation therapy alone, another 40 cases in the combination group were treated with ozone nucleus pulposus ablation therapy at once after radiofrequency thermocoagulation. Therapeutic effects were evaluated at the time points of 1 month, 3 months,6 months and 12 months after surgery by using the average scores of VAS and Macnabs standard. Results The average scores of VAS at the time points of 1 month,3 months,6 months and 12 months after surgery in both groups were significantly lower than before treatment ( all P < 0. 01 ), and it was more obviously in the combination treatment group than that in the ozone treatment group ( P < 0. 05 or P < 0. 01 ). The total efficiency within 12 months after surgery in the combination treatment group ( 91. 9% ) were higher than that in the ozone treatment group ( 74. 3% , P <0. 05 ). There were no allergic reactions, disc space infection or spinal cord, nerves, blood vessels and abdominal organ injuries and other serious complications in both two groups. Conclusion CT-guided radiofrequency thermocoagulation combined with ozone nucleus pulposus ablation was safe and minimally invasive, which was superior to that of using ozone nucleus pulposus ablation alone.关键词
