Abstract：Objective：To observe the clinical effect of Shentong Zhuyu tang combined with routine therapy patients after surgery of lumbar disc herniation(LDH). Methods：A total of 120 cases of LDH patients were randomly divided into the control group and the observation group， 60 cases in each group. After operation of percutaneous transforaminal endoscopic discectomy(PTED)， both groups were given comprehensive measures including prevention of infection， detumescence， analgesia and functional exercise，and the observation group was additionally given oral administration of modified Shentong Zhuyu tang. Both groups were treated for four weeks. Four weeks after operation，the situations of residual pain including pain degree and rates of residual pain were assessed by Visual Analogue Scale(VAS). Before operation，10 days and 28 days after operation respectively， the recovery conditions after operation were evaluated by Japanese Orthopaedic Association (JOA) score on low back pain and Oswestry Disability Index(ODI). Results：On the four weeks after operation，the clinical effect in the observation group was better than that in the control group(P＜0.05). The rate of residual pain was 5.00% in the observation group，lower than that of 23.33% in the control group(P＜0.01)，and the VAS score on residual pain was lower than that in the control group(P＜0.01). On the 10th and 28th day after operation respectively，the JOA scores on low back pain in the two groups were increased when compared with those before operation， and the ODI scores were decreased(P＜ 0.01). On the 10th and 28th day after operation respectively，the JOA scores on low back pain in the observation group were higher than those in the control group(P＜0.01)， and the ODI scores were lower(P＜0.01). Conclusion： Based on routine postoperative therapy，the additional application of modified Shentong Zhuyu tang in treating patients after operation of PTED can further relieve their low back pain， residual symptoms and residual pain after operation and promote the recovery of lumbar function and rehabilitation.
