Abstract Objective: To compare and analyze the short-term effects and follow-up results of Coflex system implantation and full laminectomy bone grafting fusion internal fixation (fusion technique) for elderly lumbar spinal stenosis (LSS). Methods: 72 elderly patients with LSS in our hospital were selected as the research subjects, and they were randomly divided into the control group and the observation group, whit 36 cases in each group. The control group was treated with fusion technique, and the observation group was implanted with Coflex system implantation. The operation condition, nerve function, pain improvement, postoperative complications and imaging indexes of the two groups were observed. Results:The operation time, intraoperative bleeding volume, the flow rate of wound and the hospitalization time in the observation group were significantly lower than those in the control group (P<0.05). The VAS scores of both groups decreased significantly at 3 months after operation (P<0.05). The JOA scores of the two groups increased significantly 6 months and 2 years after operation (P<0.05), and the change level of the observation group was significantly higher than that of the control group (P<0.05). There was no significant difference in the incidence of complications between the two groups (P>0.05). Two years after operation, there was no significant difference in the height of adjacent intervertebral space between the two groups (P>0.05). The activity of adjacent intervertebral space in the control group increased significantly (P<0.05). There was no significant change in the observation group (P>0.05). The activity of adjacent intervertebral space in the observation group was significantly lower than that in the control group (P<0.05). Conclusion:Coflex system implantation is an ideal short-term treatment for senile LSS. Two years follow-up shows that it can avoid the increase of adjacent segment intervertebral mobility to a certain extent, which is worthy of clinical application.
