Sleep Quality Assessment Among Patients Underwent Idiopathic Scoliosis Surgery

STUDY DESIGN: Retrospective study design. STUDY OBJECTIVES: To assess the prevalence and severity of sleep disturbances among patients with idiopathic scoliosis in Saudi Arabia. To evaluate the impact of surgical intervention on sleep quality in IS patients, comparing preoperative and postoperative sleep patterns. BACKGROUND: Idiopathic scoliosis (IS) is a complex spinal deformity that may impact sleep quality due to pain, breathing difficulties, and psychological factors. Surgical intervention is the primary treatment for severe cases, yet its effect on sleep quality remains unclear. METHODS: A retrospective cohort study was conducted on 70 patients who underwent scoliosis surgery at a tertiary center in Riyadh, Saudi Arabia, between 2019 and 2024. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) before and 6 months after surgery. RESULTS: The prevalence of poor sleep quality decreased significantly postoperatively from 64.2% to 44.2% ( P = 0.018). Significant improvements were observed in sleep latency ( P = 0.031), duration ( P = 0.002), efficiency ( P = 0.004), and daytime dysfunction ( P = 0.002). CONCLUSIONS: Surgical correction of idiopathic scoliosis significantly improves sleep quality by enhancing sleep parameters and reducing sleep disturbances. Further research is warranted to optimize postoperative care and improve patient quality of life.
