Predictive Value of Spinal Cord Function Classification and Sagittal Deformity Angular Ratio for Neurologic Risk Stratification in Patients with Severe and Stiff Kyphoscoliosis

摘要

BACKGROUND: Three-column osteotomies were developed to treat severe spinal deformities but result in high neurologic complications and require further risk stratification. The present study investigated whether the combination of spinal cord function classification (SCFC) and deformity angular ratio (DAR) could further stratify the neurologic risks in the surgical correction of severe and stiff kyphoscoliosis.
