Expectations for Postoperative Improvement in Health-Related Quality of Life in Young Patients With Lumbosacral Spondylolisthesis: A Prospective Cohort Study

Study Design. Prospective multicenter study of the changes in Scoliosis Research Society Outcome Questionaire 22 (SRS-22) scores for 78 patients younger than 25 years old surgically treated for lumbosacral spondylolisthesis Objective. Report the change of health-related quality of life (HRQOL) in patients younger than 25 years after surgical treatment of lumbosacral spondylolisthesis. Summary of Background Data. There is a paucity of data with regard to the influence of surgical treatment on the HRQOL of patients with lumbosacral spondylolisthesis. Large prospective studies are needed to clearly define the benefits of surgery in the young patient population. Methods. A prospective multicenter cohort of 78 patients younger than 25 years (14.8 ± 2.9, range: 7.9–23.6 yr) undergoing posterior fusion for lumbosacral spondylolisthesis were enrolled. There were 17 patients with low-grade (<50%) and 61 with high-grade (≥50%) slips. SRS-22 scores calculated before surgery and after 2 years of follow-up were compared for all patients using two-tailed paired t tests. Subanalyses for low- and high-grade patients were done using two-tailed Wilcoxon signed ranked and paired t tests, respectively. The level of significance was set at 0.05. Results. HRQOL was significantly improved 2 years after surgery for all domains and for the total score of the SRS-22 questionnaire. The individual total score was improved in 66 patients (85%), and 52 patients (67%) improved by at least 0.5 point. All domains and the total score of the SRS-22 questionnaire were significantly improved for high-grade patients, whereas only pain, function, and total score were improved for low-grade patients. Conclusion. This is the largest study comparing the HRQOL before and after surgery in young patients with low- and high-grade lumbosacral spondylolisthesis. HRQOL significantly improves after surgery for the majority of patients, especially for high-grade patients. This study helps clinicians to better counsel patients with regard to the benefits of surgery for lumbosacral spondylolisthesis. Level of Evidence: 2
