CLINICAL STUDY OF RADIOFREQUENCY TARGET THERMOCOAGULATION ABLATION COMPOUND PERCUTANEOUS INJECTION OF INTRADISC AND INTERVERTEBRAL FORAMEN WITH OZONE TO TREAT LUMBAR DISC HERNIATION

Objective: To evaluate the clinical effects of radiofrequency target thermocoagulation ablation and intradisc and intervertebral foramen injection with ozone on lumbar disc herniation.Methods: 128 patients with symptoms of sciatica and low back pain diagnosed by CT or MRI as lumbar disc herniation were selected and divided into two groups.The control group(64 cases) underwent intradiscal and intervertebral foramen injection with ozone only and the experimental group(64 cases) underwent radiofrequency target thermocoagulation ablation and intradisc and intervertebral foramen injection with ozone.The clinical results were assessed separately according to improved Macnab method and VAS on 1st day,5th day,and 6th month after treatment.Results:The excellent and good rates of two groups were 92.19%,93.75% and 90.63%,90.63% respectively at the 1st day and the 5th day after treatment,which has no statistical difference(P0.05).The excellent and good rates of the two groups were 70.31% and 92.19% respectively on 6 months after treatment,which has statistical difference(P0.05).Conclusion: Radiofrequency target thermocoagulation ablation and intradisc and intervertebral foramen injection with ozone is an effective method for the treatment of lumbar disc herniation.
