Abstract: Abstract Objective:To explore the clinical efficacy of radiofrequency thermal ablation of targets in treatment of intervertebral disc disease.Methods:After Collecting the clinical data of 130 patients comforming to the indication through CT and MRI,sixty-five patients(A group) were treated by radiofrequency thermal ablation of targets,anather sixty-five patients(B group) were cured by conservative treatment and anlysed the general clinical data and excellent and good rat in three monthes after treatment between two groups.Results:In the A groups’s patients,forty-nine patients gained excellent effects,eleven patients obtained good effects,four patients had poor effects and one cases had no effects after three monthes of the treatment of radiofrequency thermal ablation of targets with the excellent and good rate of 92.3%. In the B groups’s patients,twenty-seven patients gained excellent effects,sixteet patients obtained good effects,fourteen patients had poor effects and eight cases had no effects after three months of conservative treatment with the excellent and good rate of 66.2%.There were significant difference in treatment of intervertebral disc disease between radiofrequency thermal ablation of targets and conservative treatment(P<0.05).Conclusions:Radiofrequency thermal ablation of targets for treatment of intervertebral disc disease is a safety and efficacious treatment in the field of minimally invasive.
