ABSTRACT

Objective To evaluate the clinical efficacy of multiple target burst frequency thermocoagulation in treatment of lumbar disc herniation.Methods One hundred and twelve patients suffering from lumbar disc herniation were treated with stepped heating multiple target burst frequency thermocoagulation using of domestic R-2000B radiofrequency ablation machine.The visual analogue scale (VAS) score,Oswestry disability index (ODI) and effect of grade before operation and after operation were compared.Results The VAS score before operation was (7.60 ± 1.12) scores,3 d after operation was (3.10 ± 1.05) scores,6 months after operation was (2.90 ± 0.92) scores,there was significant difference between before operation and 3 d,6 months after operation (P ＜ 0.05).The ODI before operation was 47.6 ± 8.3,3 months after operation was 25.5 ± 6.7,6 months after operation was 23.7 ± 6.2,there was significant difference between before operation and 3,6 months after operation (P ＜0.05).The clinical efficacyexcellent grade was in 66 cases,the good was in 32 cases,the improvement was in 10 cases,the inefficacy was in 4 cases,the excellent and good rate was 87.5％ (98/112).There was no nerve injury,infection or death after operation.Conclusion Multiple target burst frequency thermocoagulation in the treatment of lumbar disc herniation has the advantages of little incision and tissue damage,fast recovery,good clinical outcome,it is worth to clinical practice.
