Abstract Objective: To investigate the effect of simple vertebral canal decompression (SVCD) in the treatment of degenerative lumbar spinal stenosis (DLSS). Method: According to the random number table method, 98 DLSS patients who came to Affiliated People's Hospital of Jiangsu University for treatment from June 2021 to May 2022 were divided into the control group and the research group, with 49 cases in each group. The control group was treated with posterior lumbar interbody fusion (PLIF), and the research group was treated with SVCD. The operation situation, treatment effect, before and after operation of spine sagittal balance parameters, spinal cord function, pain situation and lumbar function were compared between the two groups. Result: There was no significant difference in the total effective rate between the two groups (P>0.05). The operation time, intraoperative bleeding volume and postoperative bed rest time of the research group were significantly better than those of the control group (P<0.05). 6 months after operation, the lumbar lordosis, lumbar kyphosis and L4 lumbar inclination rate in both groups were significantly improved, and the improvement in the research group were more obvious than that in the control group (P<0.05). 6 months after operation, the conduction velocities of superficial peroneal nerve and deep peroneal nerve in the two groups were significantly higher than those before operation, and the latency levels of superficial peroneal nerve and deep peroneal nerve in the research group were significantly lower than those in the control group (P<0.05). The visual analogue scale (VAS) scores, Japanese Orthopaedic Association scores (JOA) and Oswestry disability index (ODI) of the two groups after 6 months operation were better than those before operation, but there were no significant differences in the scores of VAS, ODI and JOA between the two groups (P>0.05). Conclusion: SVCD in the treatment of DLSS can obviously improve the patients' operation situation, restore the spine sagittal balance, reduce spinal cord functional injury, relieve pain and promote the recovery of lumbar function, which has a good therapeutic effect.
