Correlations of spinopelvic parameters with quality of life of patients with adult degenerative scoliosis after posterior correction

Abstract

Objectives: This study aimed to investigate the correlations of spinopelvic parameters with the quality of life of patients with adult degenerative scoliosis (ADS) after posterior correction, and their relationships with efficacy

Patients and methods: Ninety patients (40 females, 50 males; mean age: 62.4±3.3 years; range, 47 to 73 years) with adult spinal deformity treated from March 2016 to May 2020 were retrospectively enrolled. The Scoliosis Research Society (SRS)-22 questionnaire was filled in by the patients, and the Oswestry disability index (ODI) and Visual Analog Scale (VAS) for back and lower limb pain were assessed. All the patients underwent posterior correction. Spearman’s analysis was conducted for the correlations of the spinopelvic sagittal parameters with quality of life. The risk factors for efficacy were identified using the multivariate logistic regression model to construct a nomogram model for efficacy and risk prediction.

Results: After the operation, significant reductions were detected in the sagittal vertical axis (SVA), pelvic tilt (PT), T1 pelvic angle (TPA), pelvic incidence minus lumbar lordosis (PI-LL), and the ODI score (p<0.05). The SVA and LL were significantly negatively correlated with all subitems on the SRS-22 questionnaire but positively correlated with VAS scores for back pain (p<0.05). Thoracic kyphosis was significantly positively correlated with self-image and mental status on the SRS-22 questionnaire (p<0.05), while TPA was negatively correlated with pain and self-image (p<0.05). The PI-LL was significantly negatively correlated with pain (p<0.05).

Conclusion: The SVA, LL, PT, and PI-LL were independent predictors of improvement in ODI after operation for ADS. The postoperative changes in spinopelvic parameters affected the clinical outcomes in patients with ADS.
