Surgery for degenerative lumbar spondylolisthesis (DLS) has traditionally been indicated for patients with neurogenic claudication. Surgery improves patients’ disability and lower extremity symptoms, but less is known about the impact on back pain.
To evaluate changes in back pain after surgery and identify factors associated with these changes in surgically-treated DLS.
Retrospective review of prospectively collected data METHODS: There were 486 consecutive patients with surgically-treated DLS who were enrolled in the Canadian Spine Outcomes Research Network (CSORN) prospective registry and identified for this study. Patients had demographic data, clinical information, disability (ODI), and back pain rating scores collected prospectively at baseline, and 12 months follow-up RESULTS: Of the 486 DLS patients, 376 (77.3%) were successfully followed at 12 months. Mean age at baseline was 66.7 (SD 9.2) years old, and 63% were female. Back pain improved significantly at 12 months, compared to baseline (p<0.001). Improvement in NRS-back pain ratings was on average 2.97 (SD 2.5) points at one year and clinically significant improvement in back pain was observed in 75% of patients (MCID NRS-Pain 1.2 points). Multivariable logistic regression revealed five factors associated with meeting MCID NRS-back pain at 12 month follow up: higher baseline back pain, better baseline physical function (higher SF-12 Physical Component Score), symptoms duration less than 1-2 years, and having no intra-operative adverse events.
Back pain improved significantly for patients treated surgically for DLS at 1-year follow-up.
