远红外热成像可作为射频热凝靶点消融结合臭氧治疗腰椎间盘突出症临床疗效的客观评价指标

Curative effect of radiofrequency thermocoagulation combined with ozone injection for lumbar disc herniation evaluated by far-infrared thermography

背景:目前对腰椎间盘突出症患者的疗效判定仍主要依靠患者的自觉症状和物理检查,尚缺乏客观评价手段。目的:应用远红外热像技术评估射频热凝靶点消融术结合臭氧治疗腰椎间盘突出症的临床疗效。方法:选择46例符合条件的腰椎间盘突出症患者,随机分为射频治疗组23例和保守治疗组23例,分别予以射频热凝靶点消融术结合臭氧治疗和传统保守治疗,治疗前后使用远红外热像仪检测双下肢温度差,并与临床改善情况进行对比分析。结果与结论:射频治疗组与保守治疗组的显效率分别为52%和17%,有效率分别为96%和65%,两组差异均有显著性意义(P<0.05);射频治疗组治疗后热图温差明显低于保守治疗组(P=0.00);射频治疗组治疗前后温差改变比保守治疗组明显增大(P=0.00)。结果可见红外热成像技术可作为射频热凝靶点消融术结合臭氧治疗腰椎间盘突出症疗效的一种客观评估指标。

BACKGROUND： To data, the determination of the curative effect on the patients with lumbar disc herniation mainly depends on the subjective symptom and physical examination, there still lacks a subjective evaluation method. OBJECTIVE： To evaluate the curative effect of the radiofrequency thermocoagulation combined with ozone injection for lumbar disc herniation evaluated by far-infrared thermography. METHODS： Forty-six patients who got lumbar disc herniation and matched all the conditions for our clinical research were selected. The patients were randomly divided into the radiofrequency treatment group and conservative treatment group. Each group had 23 cases and was treated with radiofrequency thermocoagulation combined with ozone injection treatment and conservative treatment respectively. Thermography was taken before and after treatment to detect the difference of lower limbs＇ temperature and compared with the effects assessed by visual analogue scale. RESULTS AND CONCLUSION： The remarkable effective rates of radiofrequency treatment group and conservative treatment group were 52% and 17% respectively, and the effective rates were 96% and 65% There was statistical difference of curative effect between the two groups （P 〈 0.05）; the difference of temperature in thermograph was obviously decreased in radiofrequency treatment group after treatment compared to conservative treatment group （P = 0.00）; the change in temperature before and after the treatment was significantly increased in radiofrequency treatment group compared to conservative treatment group （P = 0.00）. Far-infrared thermography can be used as an objective indicator to evaluate the curative effect of radiofrequency thermocoagulation combined with ozone injection for lumbar disc herniation.
