Comparison of efficacy and safety of low-temperature plasma ablation and radiofrequency thermocoagula-tion in the treatment of lumbar disc herniation
Objective To compare the clinical efficacy and safety of low-temperature plasma ablation and radiofrequency ther-mocoagulation in the treatment of lumbar disc herniation(LDH).Methods 58 patients with LDH admitted to the Department of Pain of the First Affiliated Hospital of Nanjing Medical University were selected and randomly divided into LTPA group and RFTC group.Numer-ical Rating Scale(NRS)was used to evaluate the pain level and the Oswestry Disability Index(ODI)was used to evaluate the lumbar func-tion.The modified MacNab criteria were used to evaluate the surgical efficacy.Surgery-related complications were evaluated for surgical safety.Results Compared with pre-operation,NRS and ODI were significantly improved in the two groups after operation(P＜0.05).The NRS score and the ODI score of LTPA group were lower than those of RFTC group at 3 days,1,3,6 months and 1 year after operation(P＜0.05).According to the modified Macnab criteria,the excellent rate of patients in LTPA group was better than those in RFTC group,and the difference was statistically significant at 1 year after operation(P＜0.05).There was no significant difference in operation-related com-plications between the two groups(P＞0.05).Conclusion LTPA and RFTC can safely and effectively relieve pain and improve the mobility caused by LDH.The long-term efficacy of LTPA is better than that of RFTC.
