CLINICAL EFFECT OF MINIMALLY INVASIVE OVERLAPPING TREATMENT FOR DISCOGENIC LOW BACK PAIN
Objective To investigate the clinical effect of radiofrequency thermocoagulation+ozone ablation of intervertebral disc,ozone ablation of intervertebral foramen,and radiofrequency thermocoagulation of the posterior ramus of spinal nerve+ozone ablation occlusion in the treatment of discogenic low back pain.Methods A total of 68 patients with discogenic low back pain underwent minimally invasive percutaneous puncture and overlapping treatment from February 2012 to February 2014.The Nakano criteria were used to evaluate treatment outcome at the last follow-up visit;the Oswestry score was used for functional evaluation before surgery and at 1,4,and 12 weeks after surgery.Results The time of operation ranged from 20 to 40 minutes (mean 30 minutes).The patients were followed up for 6-18 months (mean 14.8 months),and no surgical complications were found.According to the Nakano criteria at the last follow-up visit,61 patients had an excellent outcome,4 had a good outcome,and 3 had a fair outcome,while no patient had a poor outcome,resulting in an excellent and good rate of 95％.There were significant changes in the Oswestry score at 1,4,and 12 weeks after surgery (8.4±5.6,8.5±5.1,8.6±5.3 vs 21.1±6.9 before surgery;F=81.14,P ＜0.05).Conclusion Minimally invasive percutaneous puncture and overlapping treatment have a satisfactory short-term clinical effect in the treatment of discogenic low back pain.
