However, it is less clear how it impacts coexisting low-back pain (LBP). The aim of this study was to quantify the change in LBP after lumbar decompression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>This study analyzed data from the British Spine Registry on patients who underwent lumbar decompression surgery. LBP severity was assessed using the visual analog scale (VAS), and the primary outcome was the change in VAS score at 1 year, with secondary outcomes measuring the change in score at 6 weeks, 6 months, and 2 years. The minimal clinically important difference (MCID) was defined as a 30% reduction in pain.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>Of the 25,349 patients included in the study, 92.2% reported significant back pain at baseline. Of the entire cohort, 12,951 (55.4%) patients had follow-up data for 6 weeks, 9066 (38.8%) for 6 months, 7926 (33.9%) for 1 year, and 5517 (23.6%) for 2 years; 17,304 (68.3%) patients had follow-up data for at least one time point. Sixty-two percent of patients attained the MCID (VAS score \u2265 30%) in back pain reduction, with 51% reporting a substantial improvement (VAS score \u2265 50%). This improvement was observed by 6 weeks postoperation and was mostly maintained at 2 years. Patients with back pain predominance were more likely to attain the MCID compared with those with leg pain predominance (63.6% vs 60.1%; OR 1.16, 95% CI 1.02\u20131.34; p = 0.0291). Severity of baseline back pain did not reduce the proportion attaining the MCID.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>Regardless of pain presentation, LBP improves in approximately 62% of patients who undergo lumbar decompressive surgery, with 51% experiencing substantial improvement. Patients undergoing lumbar decompression can be advised on the chance of a meaningful improvement in back pain postsurgery.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/2023.5.spine23116","type":"journal-article","created":{"date-parts":[[2023,7,22]],"date-time":"2023-07-22T11:56:05Z","timestamp":1690026965000},"page":"583-592","source":"Crossref","is-referenced-by-count":12,"title":["Does low-back pain improve after decompressive spinal surgery?
