Background: Spinal canal stenosis is the most common degenerative disease of the lumbar spine. Sagittal imbalance in degenerative spinal diseases is associated with disability and reduced quality of life. In this study, we examined the effect of lumbar spine laminectomy on improvement in spinopelvic sagittal parameters.Methods: This prospective cohort study was conducted during 2016-2019 at Ghaem and Shahid Kamyab hospitals, Mashhad, Iran. Patients underwent spinal radiography before and after laminectomy, and their spinopelvic sagittal parameters were measured. Data were analyzed using SPSS considering P < 0.050 statistically significant.Findings: Overall, 46 patients were examined in this study. The mean age was 52.9 ±11.9 years, 29 patients (63%) were men, and 17 (37%) were women. 28 subjects (60.9%) underwent 3-level and 18 subjects (39.1%) underwent 4-level laminectomy. Only the lumbar lordosis and sagittal vertical axis (SVA) were significantly changed after the surgery (P < 0.050).Conclusion: Lumbar canal stenosis disrupted the sagittal and global spinal balance. Multi-level laminectomy improved lumbar lordosis and SVA in lumbar canal stenosis.
