Effect of Bone Cement Reinforced Pedicle Screw Fixation on Intervertebral Fusion Rate of patients with Lumbar Spinal Stenosis and Osteoporosis and Long-Term Effect Analysis
Objective To investigate effect of bone cement reinforced pedicle screw fixation on intervertebral fusion rate of patients with lumbar spinal stenosis and osteoporosis,and analyze its long-term effect.Methods The paper chose 52 patients with lumbar spinal stenosis and osteoporosis admitted to our hospital from July 2019 to December 2019,and divided them into experimental group and control group randomly,with 26 cases in each group.52 cases were treated with laminectomy,intervertebral disc removal,intervertebral bone grafting fusion,and pedicle screw internal fixation.Experimental group was fixed with bone cement reinforced pedicle screws,while control group with ordinary pedicle screws.Preoperative and postoperative effect related scores,and conduct lumbar spine X-ray examination were recorded six months after surgery to understand status of intervertebral fusion.Results There was no statistically significant difference in VAS scores,JOA scores,and ODI scores recorded before and 2 weeks after surgery between two groups(P>0.05).VAS scores,JOA scores,and ODI scores recorded from 3 months after surgery to 2 years after surgery showed significant difference and statistical significance(P<0.05).Six months after surgery,intervertebral fusion rate determined Bridwell criteria showed significant difference between two groups.Intervertebral fusion rate of experimental group was significantly higher than control group,difference was statistically significant(P<0.05).Conclusion Bone cement reinforced pedicle screw fixation technology can improve rate of interbody bone grafting fusion,and satisfaction effect after two years of surgery effectively.There is some controversy about the safety of the technology,and advantages outweigh the disadvantages,which is worthy of further promotion in clinical practice.
