BACKGROUND CONTEXT Surgery for degenerative lumbar spondylolisthesis (DLS) has traditionally been indicated for patients with neurogenic claudication and radicular pain. Surgery improves patients’ disability and lower extremity symptoms, but little is known about the impact on back pain. PURPOSE This study aims to evaluate changes in back pain after surgery and identify prognostic factors influencing these changes in surgically treated DLS. METHODS Consecutive patients with DLS surgically treated were prospectively enrolled in the Canadian Spine Outcomes Research Network (CSORN) registry. Patients had demographic data, clinical information, disability (ODI), and back pain (NRS Back Pain) scores collected prospectively at baseline, 3-, 12-, and 24-month follow-up. Results were compared to baseline using simple summary statistics and factors associated with improved back pain were assessed with multivariate regression (significance was p RESULTS A total of 557 patients were identified; all had reached 3-month follow-up; 376 (67.5%) had reached 12-month follow-up; and 141 (25.3%) had reached 24-month follow-up. Mean age at baseline was 66.2 (+/−9.5), and 58.5% were female. Back pain improved significantly at 3 months, and was maintained at 12, and 24-month follow-up compared to baseline (p CONCLUSIONS Back pain improved significantly during follow up for patients treated surgically for DLS. This research demonstrates that for patients undergoing surgery for DLS, the majority will have improved back pain at 1-year follow-up.
