Objective

2

To observe the clinical efficacy of Duhuo Jishengtang combined with minimally invasive decompression of lumber spine in the treatment of degenerative lumbar spinal stenosis with kidney deficiency syndrome for more than 3 years.

Method

2

Through a single-center parallel randomized controlled clinical trial， 63 patients with degenerative lumbar spinal stenosis who were hospitalized in Jiangsu Hospital of Traditional Chinese Medicine from October 2015 to April 2017 were observed for more than three years. Among them， there were 31 cases in the operation combined with traditional Chinese medicine group （observation group） and 32 cases in the operation combined with Celebrex and Mecobalamin group （control group）. Both groups were given routine treatment. The observation group was treated with Duhuo Jishengtang for 3 weeks， while the control group was treated with Celebrex and Mecobalamin for 3 weeks.

Result

2

In the aspect of pain improvement， only 3 months after operation， the observation group was superior to the control group （

There was no unstable performance in the last follow-up of the two groups. There was no statistically significant difference between two groups.

Conclusion

2

The middle and long-term follow-up for minimally invasive decompression of lumber spine showed a satisfactory efficacy in the treatment of degenerative lumbar spinal stenosis， with no impact on the stability of the operative segments. For patients of lumbar spinal stenosis with kidney deficiency syndrome， Duhuo Jishengtang can promote the recovery of postoperative neurological function， and improve the good efficacy rate of clinical treatment， but with no obvious advantage in pain relieve after operation.
