This prospective multicenter study enrolled 492 consecutive adult spinal deformity patients across 11 U.S. sites. It asked which radiographic parameters best predict patient disability and derived specific thresholds for severe impairment. Coronal Cobb angle — the historical gold standard — was far less predictive than sagittal spinopelvic measurements.
