Abstract： Objective： To observe the clinical effect of du- moxibustion on ginger and garlic for low back pain after interbody fusion and internal fixation. Methods：A total of 120 cases of patients with low back pain after interbody fusion and internal fixation were randomly divided into two groups，60 cases in each group. The control group was simply treated with celecoxib capsules，and the treatment group was additionally treated with du-moxibustion on ginger and garlic based on the treatment of the control group. Both groups were treated for two courses， seven days being a course. Results： After treatment for 7 and 14 days，the total effective rates were 81.7% and 96.7% in the treatment group respectively，and 68.3% and 86.7% in the control group，differences being significant(P＜0.05). After treatment for 7 and 14 days，the VAS scores in the two groups were decreased when compared with those before treatment(P＜0.05)，and the score in the treatment group was lower than that in the control group(P＜0.05). After treatment for 7 and 14 days，the JOA scores in the two groups were increased when compared with those before treatment(P＜0.05)，and the score in the treatment group was higher than that in the control group(P＜0.05). After treatment for 7 and 14 days， the numbers of tender points in the two groups were decreased when compared with those before treatment(P＜0.05)， and the number in the treatment group was lower than that in the control group(P＜0.05). After treatment for 7 and 14 days， The lumbar flexion and extension activity of the two groups were improved(P＜0.05)， and The improvement of lumbar flexion and extension in the treatment group was more significant than that in the control group(P＜0.05). Conclusion： Based on the treatment of celecoxib capsules， dumoxibustion on ginger and garlic can effectively improve pain and lumbar function after interbody fusion and internal fixation with significant clinical effect.
