Analysis of Short-and Long Term Efficacy and Prognostic Factors of Minimally Invasive Transforaminal Lumbar Intervertebral Fusion in Patients with Lumbar Spinal Stenosis
Objective:To explore the short-term and long-term efficacy and prognostic factors of minimally invasive lumbar interbody fusion surgery for patients with lumbar spinal stenosis.Methods:Retrospective analysis of 70 patients with lumbar spinal stenosis admitted from January 2020 to December 2021,evaluating various indicators of the patients.Divide the follow-up results into a good prognosis group(n=52)and a poor prognosis group(n=18),compare their general clinical conditions,and analyze the factors affecting prognosis.Results:All patients showed a decrease in ODI and VAS scores from preoperative to 2 years postoperatively,with a more significant decrease observed at 2 years postoperatively(P<0.05);The postoperative segmental fusion rate was 94.87%,and the total incidence of postoperative complications was 11.43%;The number of patients with lumbar spondylolisthesis,lumbar spinal stenosis,and osteoporosis in the prognostic group showed significant differences and were independent factors affecting poor prognosis(P<0.05).Conclusion:Minimally invasive transforaminal lumbar interbody fusion for patients with lumbar spinal stenosis has better short-term and long-term efficacy,with a higher postoperative fusion rate and lower incidence of complications.However,there are still some patients with poor prognosis who need to adjust their intervention or treatment plans appropriately.
