Inclusion Criteria: * Age 6 to 20 years at the time of enrollment. * Diagnosis of paralytic scoliosis secondary to spinal cord injury during childhood. * Severe pelvic obliquity, defined as pelvic obliquity angle greater than 15 degrees on sitting full-spine anteroposterior radiographs. * Major coronal scoliosis curve with Cobb angle greater than 40 degrees, or progressive deformity considered to require surgical correction by the treating spine deformity team. * Nonambulatory status or severe lower-limb motor dysfunction after spinal cord injury. * Planned surgical correction requiring spinopelvic fixation. * Ability to undergo sitting full-spine radiographic assessment before surgery and during follow-up. * Written informed consent provided by the parent or legal guardian, with participant assent when applicable. Exclusion Criteria: * Idiopathic scoliosis, congenital scoliosis, syndromic scoliosis, or spinal deformity caused by etiologies other than spinal cord injury. * Neuromuscular scoliosis caused by cerebral palsy, spinal muscular atrophy, muscular dystrophy, myelomeningocele, poliomyelitis, or other primary neuromuscular diseases. * Previous spinal deformity correction surgery or previous long-segment spinal fusion. * Active systemic infection or uncontrolled local infection at the planned surgical site. * Severe pressure ulcer, osteomyelitis, or soft tissue condition that precludes safe posterior spinal surgery. * Severe cardiopulmonary, hematologic, hepatic, renal, or other systemic disease that makes the participant unsuitable for major spinal surgery. * Coagulation disorder or other condition associated with unacceptable bleeding risk. * Inability to complete the planned follow-up schedule. * Participation in another interventional trial that may affect the outcomes of this study.
