PURPOSE: A curve magnitude at which posterior spinal fusion (PSF) is indicated for children with cerebral palsy (CP) scoliosis is not defined. We sought to evaluate whether agreement exists for a curve magnitude at which PSF is undertaken for CP scoliosis and to evaluate outcomes by quartile of curve magnitude and flexibility at time of fusion. METHODS: A prospective multicenter pediatric spine database was queried for patients with a Gross Motor Function Classification Scale (GMFCS) IV or V who underwent PSF for CP scoliosis. Demographics, surgical indications, and correlations between curve magnitude, postoperative radiographic outcomes, and Caregiver's Priorities and Child Health Index of Life and Disabilities (CPCHILD) scores were evaluated for patients with at least 2 years of follow-up. RESULTS: 489 patients from 15 sites were analyzed. Median major Cobb angle at time of PSF was 87° and significantly varied by site (p
