    Objective: Spinal stenosis, characterized by spinal canal narrowing and neural structure compression, leads to debilitating symptoms and impacts quality of life. Surgical interventions for spinal stenosis are on the rise because of an aging population and advancing surgical techniques. However, complications can undermine outcomes. Understanding the factors contributing to complications is crucial for optimizing outcomes. This study aimed to identify complications and disability factors in patients undergoing posterior spinal instrumentation for spinal stenosis. Materials and Methods: Data from patients who underwent surgery for degenerative spinal stenosis were retrospectively analyzed. Factors including age, gender, cage usage, instability, and preoperative mobility were evaluated. Complications, including infection and adjacent segment degeneration, were documented. Statistical analysis was performed to identify correlations and significant differences. Results: Sixty four patients were included in the study. 79.7% of the patients were women. The mean follow-up time was 46.56 months. The study revealed correlations between preoperative mobility status and infection rates, with immobile patients at higher risk (p=0.034). Gender disparities were noted, with female patients exhibiting more functional disability (Oswestry score female 12.41, male 7.00, p=0.044). Cage usage correlated with worse outcomes (p=0.007), and spinal instability was associated with poorer functional scores (p=0.015). Complications were observed in 13 (20.3%) patients. Infection was detected in 5 patients, postoperative neurodeficiency in 2 patients, re-operation in 13 patients (20.3%), and adjacent segment degeneration in 9 patients (14.1%). Conclusion: Despite limitations, this study provides valuable insights into factors influencing complications and disability in spinal stenosis surgery. Tailoring interventions based on these findings could enhance patient outcomes. © 2023 The Author.
