Effect of Laminar Decompression Fusion Internal Fixation in the Treatment of Degenerative Lumbar Spinal Stenosis
Objective:To investigate the effect of laminar decompression fusion internal fixation in the treatment of degenerative lumbar spinal stenosis(DLSS).Method:A total of 98 patients with DLSS who treated in Xishui County Hospital of Traditional Chinese Medicine from March 2021 to March 2023 were selected as the study objects,and they were divided into the control group(simple laminar decompression)and the observation group(laminar decompression fusion internal fixation)by using the random number table method,49 cases each in each group,and the lumbar spine function[Japanese Orthopaedic Association Assessment and Treatment(JOA)],the degree of pain[visual analog scale(VAS)],and the imaging indicators[thoracic posterior convexity angle,lumbar anterior convexity angle,pelvic tilt angle,cone slip degree,slip angle,disc height],inflammatory indicators[tumor necrosis factor-α(TNF-α),interleukin-1α(IL-1α),C-reactive protein(CRP)]and treatment effect of two groups were compared.Result:Before operation,there were no statistically significant differences in VAS score and JOA score between two groups(P>0.05);at 6 months after operation,the VAS scores were decreased and JOA cores were increased in two groups compared with those before operation,and the VAS score in the observation group was lower than that of the control group,and the JOA score was higher than that of the control group,the differences were statistically significant(P<0.05).Before operation,there were no statistically significant differences in the thoracic posterior convexity angle,lumbar anterior convexity angle,pelvic tilt angle,conus slip degree,slip angle,and intervertebral disc height between two groups(P>0.05);at 6 months after operation,the conus slip degree and slip angle in two groups were decreased compared with those before operation,and which in the observation group were lower than those the control group,and the intervertebral disc height,thoracic posterior convexity angle,lumbar anterior convexity angle and pelvic tilt angle were increased compared with those before operation,and which in the observation group were higher than those in the control group,and the differences were statistically significant(P<0.05).Before operation,there were no significant differences in the levels of inflammatory factors between the two groups(P>0.05);at 6 months after operation,the levels of TNF-α,IL-1α and CRP in two groups were lower than those before operation,and which in the observation group were lower than the control group,the differences were statistically significant(P<0.05).The excellent rate of the observation group was higher than that of the control group,and the difference was statistically significant(P<0.05).Conclusion:DLSS treated with laminar decompression fusion internal fixation has a significant effect,it can improve lumbar function,inhibit inflammatory response and reduce pain.
