Methods: Patients undergoing lumbosacral instrumented fusions for degenerative spine disease underwent; standing lumbopelvic X-rays and lumbar MRI scans obtained both preoperatively and 1 year postoperatively. Parameters measured included lumbar lordosis (LL), L4-S1 angle, pelvic incidence (PI), and LL-PI mismatch. Results: Fifty patients were followed for 1 year following lumbopelvic fusion. There was a statistically significant difference in the L4-S1 angle between patients with good versus poor clinical outcomes at 1 year postoperative; the LL-PI mismatch showed a strong positive correlation with better outcome scores. Conclusion: Preservation of an adequate LL/other lumbosacral parameters favorably impacts patients’ outcomes following lumbosacral fusion for degenerative disease.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/04dc73f8-9dcf-4eb9-a11f-b3faecc72999/featured/hero-1781562887464.png","publishDate":"2020-12-16T00:00:00.000Z","doi":"10.25259/SNI_704_2020","categories":["Spine","Original Article"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/04dc73f8-9dcf-4eb9-a11f-b3faecc72999/pdf"}
