Abstract
The authors aimed to evaluate the prevalence of sleep disturbance in patients with grade 2 lumbar spondylolisthesis and assess postoperative trajectories and predictors of improvement at 5 years. They hypothesized that surgical treatment of grade 2 spondylolisthesis would result in high rates of long-term improvement in sleep disturbance. Patients with grade 2 lumbar spondylolisthesis were identified from the 14-site Spine CORe™ study group within the Quality Outcomes Database (QOD). Sleep disturbance was measured using the sleep item of the Oswestry Disability Index (ODI) at baseline and 3, 12, 24, and 60 months postoperatively. The prevalence of baseline sleep disturbance was determined. Clinically meaningful improvement was defined using minimal clinically important difference thresholds. Predictors of improvement were analyzed using multivariate Firth's logistic regression, and associations with pain, disability, quality of life, and satisfaction were assessed. A total of 328 patients underwent surgery for grade 2 spondylolisthesis. At baseline, 300 of 328 patients (91.5%) reported sleep disturbance. The 60-month follow-up rate in this subgroup was 81% (21 died within 5 years of surgery of unrelated causes and 223 of the 300 patients followed up at 5 years). Improvement in sleep disturbance was observed in 165 patients (74.0%), while 58 patients (26.0%) continued to report sleep disturbance at 60 months. Those with improved sleep were more likely to achieve clinically meaningful gains in back pain (80.5% vs 50.0%, p < 0.001), leg pain (83.6% vs 53.4%, p < 0.001), EQ-5D (31.1% vs 7.3%, p < 0.001), and ODI (62.8% vs 5.3%, p < 0.001) scores, with a trend toward higher satisfaction in patients with improved sleep (88.5% vs 77.8%; risk difference 10.7%, 95% CI -0.01 to 0.23). On multivariate analysis, only private insurance (OR 2.20, 95% CI 1.03-4.78; p = 0.041) was associated with greater odds of 60-month sleep improvement. Sleep disturbance was highly prevalent in 91.5% of patients with grade 2 spondylolisthesis, and 74.0% experienced meaningful improvement by 3 months and this was sustained for 5 years following surgery. Sleep recovery was closely tied to gains in pain, disability, and quality of life. These results demonstrate that surgery for grade 2 spondylolisthesis not only improves mechanical symptoms but also substantially alleviates sleep disturbance.

I have more than 25 years of experience treating patients of all ages with spinal disorders. I have had an interest in the management of spinal disorders since starting my medical education. I performed residencies in both orthopaedic surgery and neurosurgery to gain a comprehensive understanding of the entire range of spinal disorders. My goal has been to find innovative ways to manage the range of spinal conditions, straightforward to complex. I have a focus on managing patients with complex spinal disorders. My patient evaluation and management philosophy is to provide engaged, compassionate care that focuses on providing the simplest and least aggressive treatment option for a particular condition. In many cases, non-operative treatment options exist to improve a patient’s symptoms. I have been actively engaged in clinical research to find the best ways to manage spinal disorders in order to achieve better results with fewer complications.

I specialize in the surgical management of all complex cervical, thoracic, lumbar, or sacral spinal diseases by using minimally invasive as well as standard approaches for arthritis or degenerative disease, deformity, tumors, and trauma. I have a special interest in the treatment of thoracolumbar deformities, occipital-cervical problems, and in helping patients with complex spinal issues from previously unsuccessful surgery or recurrent disease.I listen to my patients to understand their symptoms and experiences so I can provide them with the information and education they need to manage their disease. I make sure my patients understand their treatment options, and what will work best for their individual condition. I treat all my patients with care and concern – just as I would treat my family. I am available to address my patients' concerns before and after surgery. I aim to improve surgical outcomes for my patients and care of all spine patients with active research evaluating clinical and radiological results after spine surgery with multiple prospective databases. I am particularly interested in prevention of spinal deformity, infections, complications, and recurrent spinal disease. Also, I study whether patient specific variables including pelvic/sacral anatomy and sagittal spinal balance predict complications from spine surgery.
