We assessed whether decompression for central lumbar spinal stenosis (CLSS) provided meaningful improvement in patients aged 50\u201395 years.Methods: We evaluated preoperative and 1-year postoperative Numerical Rating Scale (NRS) leg and back pain, Oswestry Disability Index (ODI), and complications in 17,987 patients aged \u226550 years undergoing decompression without fusion for CLSS without spondylolisthesis from the Swespine register. Meaningful improvement was defined using minimal clinically important difference (MCID) thresholds for NRS leg\/back pain and ODI. Across 5-year age groups, we assessed the proportions improving \u2265MCID and odds ratios (ORs) with 95% confidence intervals (CIs), using ages 65\u201369 years as the reference group.Results: Across age groups, 71%\u201380% improved \u2265MCID in \u22651 outcome. Compared with the reference group, ORs (95% CI) for \u2265MCID improvement were lower in ages 70\u201374 (0.8; 0.7\u20131.0), 75\u201379 (0.7; 0.6\u20130.8), 80\u201384 (0.6; 0.5\u20130.7), and 85\u201389 (0.6; 0.5\u20130.8); no other age groups differed. 5%\u201312% experienced complications. Compared with the reference group, ORs (95% CI) for complications were higher in ages 75\u201379 (1.3; 1.1\u20131.6), 80\u201384 (1.7; 1.4\u20132.1), and 85\u201389 (2.0; 1.5\u20132.8), and lower in ages 55\u201359 (0.7; 0.5\u20130.9).Conclusion: 77% of patients aged 50\u201395 years improved \u2265MCID after decompression without fusion for CLSS without spondylolisthesis. Although outcomes were slightly worse and complication rates higher in older than younger patients, decompression without fusion remains effective across this age range.<\/jats:p>","DOI":"10.14245\/ns.26520722.0361","type":"journal-article","created":{"date-parts":[[2026,7,30]],"date-time":"2026-07-30T09:15:42Z","timestamp":1785402942000},"page":"580-592","update-policy":"https:\/\/doi.org\/10.14245\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Clinically
