ABSTRACT
Objective To observe the curative effect of Bushen-Tongdu decoction combined with percutaneous minimally invasive decompression for degenerative lumbar spinal stenosis. Methods A total of 80 patients with degenerative lumbar spinal stenosis were selected and divided into two groups of 40 cases by random number table. The control group was treated with percutaneous transforaminal minimally invasive decompression. The treatment group was given Bushen-Tongdu decoction on the basis of the control group. Both groups were treated for 14 days. The Japanese orthopedic Society back pain evaluation criteria for waist pain, leg pain and numbness, walking ability, sensory dysfunction, dyskinesia, straight leg raising test score were collected and compared. Results The total effective rate was 95.00％ (38/40) in the treatment group and 82.50％ (33/40) in the control group. The total effective rate of the two groups was statistically significant (Z=-2.357,P=0.018). After treatment, the levels of waist pain score, leg pain and numbness score, walking ability score, sensory dysfunction score, dyskinesia score and the straight leg raising test score in the treatment group were significantly higher than those in the control group(t=-2.180, -2.059, -1.985, -2.177, -2.045, -2.238, P<0.05).Conclusions The Bushen-Tongdu decoction combined with percutaneous minimally invasive decompression can reduce pain, improve walking ability, improve sensory and motor dysfunction, and improve clinical efficacy of the patients with degenerative lumbar spinal stenosis.
