Clinical outcomes after surgical treatment of severe congenital spinal deformity in skeletally mature patients: A minimum two-year follow-up study

Sustained spinal correction and favorable patient-reported outcomes for at least 2 years postoperatively were obtained in skeletally mature patients with severe congenital spinal deformities. However, the patients showed high rates of complications that were significantly associated with kyphotic deformity, larger sagittal curve magnitude, higher DAR values, and increased fusion levels.
