Comparative Analysis on Curative Effect of Minimally Invasive Posterior Lumbar Decompression and Fusion and Traditional Total Laminectomy for Elderly Lumbar Spinal Stenosis

Objective: To compare the curative effect of minimally invasive posterior lumbar decompression and fusion and traditional total laminectomy for elderly lumbar spinal stenosis, and to study its clinical application value. Methods: 76 cases of elderly patients with lumbar spinal stenosis treated in hospital from July 2009 to January 2013 were selected, 43 patients were treated with minimally invasive posterior lumbar decompression and fusion(group A), 33 patients underwent the traditional total laminectomy(group B).All patients were followed up for 6 months ~2 years(average 1 year and 7 months). Operation situation, the postoperative incidence of adverse reactions and JOA score of the two groups were compared and analysed. Results: Group A presented smaller operation incision,less bleeding and shorter hospital stay, and the differences were statistically significant compared with the group B(P0.05); There was no statistically significant difference in adverse reactions between the two groups(P0.05); The JOA score of group A was significantly higher than that of group B, wihch showed the effect of group A was better than group B. Conclusion: Minimally invasive posterior lumbar decompression and fusion has obvious curative effect in elderly patients with lumbar spinal stenosis for smaller operation incision,less bleeding reduce risk, and smaller risk of postoperative incidence of adverse reactions, so it is worthy of popularization and application.
