Objective: To investigate the effects of heat fumigation with Hai Tong Pi decoction and Chinese bone-setting manipulation on patients with lumbar disk herniation. Methods: 126 patients with lumbar disk herniation who visited the orthopedic department of our hospital from January 2022 to May 2023 were included and divided into two groups of 63 cases each according to the method of randomized numerical table. Conventional lumbar traction treatment was applied in the control group, while in the study group, heat fumigation with Hai Tong Pi decoction and traditional Chinese bonesetting manipulation were adopted in addition to conventional lumbar traction treatment. The total effective rate was compared between the groups, and the lumbar spine mobility, lumbar spine function scores, and symptom scores were compared between and within the groups. Results: After treatment, the total effective rate in the study group was higher than that in the control group (P < 0.05). The lumbar spine mobility and lumbar spine function scores after treatment were significantly higher in both groups compared with those before treatment, while lumbar spine mobility and lumbar spine function scores were higher in the study group than in the control group (P < 0.05). After treatment, the scores of symptoms such as lumbar back pain, radiating pain in the lower limbs, and urinary and defecation disorders were significantly lower in both groups compared with those before treatment, while the scores of each symptom in the study group were lower than those in the control group (P < 0.05). Conclusion: In the treatment of patients with lumbar disk herniation, the combined application of heat fumigation of Hai Tong Pi decoction and Chinese bone-setting manipulation can enhance the treatment effectiveness, improve the lumbar spine function, lumbar spine mobility, and lumbar back pain.
