However, lumbar fusion can cause adjacent vertebral diseases, about 50% of which is spinal stenosis. Unilateral laminectomy is an effective treatment for lumbar spinal stenosis. Therefore, this study aims to assess whether concurrent unilateral laminotomy decompression of the proximal adjacent vertebrae during primary lumbar fusion reduces long\u2010term adjacent spinal stenosis incidence.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n Patients (\n n<\/jats:italic>\n \u2009=\u2009179) who underwent lumbar fusion surgery between January 2021 and June 2023 were included in this retrospective analysis. A total of 110 patients underwent single\u2010segment lumbar fusion surgery, including 28 (A1) in the adjacent vertebral decompression group and 82 (B1) in the non\u2010decompression group. The mean follow\u2010up duration was 11.74\u2009\u00b1\u20094.64\u2009months for group A1 and 12.01\u2009\u00b1\u20094.83\u2009months for group B1. 69 patients underwent two\u2010segment lumbar fusion surgery, including 28 (A2) in the adjacent vertebral decompression group and 41 (B2) in the non\u2010decompression group. The mean follow\u2010up duration was 12.49\u2009\u00b1\u20094.57\u2009months for group A2 and 12.12\u2009\u00b1\u20095.97\u2009months for group B2. The visual analog scale (VAS) score, Oswestry disability index (ODI), and dural sac cross\u2010sectional area (DSCA) were used to evaluate clinical outcomes. Operation time, blood loss, and complications were recorded. All continuous variables with normal distribution were analyzed using the\n t<\/jats:italic>\n \u2010test, while count data were compared using the chi\u2010square test or Fisher's exact test.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n After surgery, the DSCA of the adjacent vertebral canal in the adjacent vertebral decompression group was significantly increased (A1: 111.64\u2009\u00b1\u200924.45 vs. 135.69\u2009\u00b1\u200935.46\u2009mm\n 2<\/jats:sup>\n ,\n p<\/jats:italic>\n \u2009<\u20090.001; A2: 99.95\u2009mm\n 2<\/jats:sup>\n \u2009\u00b1\u200916.81 vs. 115.29\u2009\u00b1\u200921.19\u2009mm\n 2<\/jats:sup>\n ,\n p<\/jats:italic>\n \u2009<\u20090.001).
