Eligible participants (n\u2009=\u2009100) were adults with LSS who underwent decompression with or without fusion and were followed up using validated questionnaires to assess pain (VAS back, VAS leg) and disability (ODI, RMDQ). Statistical analyses included t-tests, ANOVA, and logistic regression to evaluate clinical outcomes.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Fifty-seven patients underwent decompressive surgery (SD), and 43 underwent decompression with fusion (DF). DF patients were younger (67.67 vs. 73.07 years, <jats:italic>p<\/jats:italic>\u2009=\u20090.0008) and more likely to exhibit radiological markers of instability, including L5-S1 involvement (<jats:italic>p<\/jats:italic>\u2009=\u20090.0315) and Grade 1 spondylolisthesis (<jats:italic>p<\/jats:italic>\u2009=\u20090.0118). Both groups showed significant improvements in pain and disability scores (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001), with no significant differences between groups at follow-up. DF was associated with longer hospital stays (3.07 vs. 1.70 days, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001) but fewer revision surgeries (2.33% vs. 15.79%, <jats:italic>p<\/jats:italic>\u2009=\u20090.0402). Higher BMI reduced odds of ODI improvement in the SD group (<jats:italic>p<\/jats:italic>\u2009=\u20090.0252), while older age decreased the odds of RMDQ improvement in the DF group (<jats:italic>p<\/jats:italic>\u2009=\u20090.0102).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>Both surgical approaches yielded significant improvements in pain and disability for patients with LSS.
