Posterior Minimally Invasive Surgery for Treating Paralytic Scoliosis With Pelvic Obliquity in Children Following Spinal Cord Injury

This randomized controlled trial compares posterior minimally invasive correction surgery with conventional posterior spinal fusion for children with paralytic scoliosis and severe pelvic obliquity following spinal cord injury. Conventional posterior spinal fusion is widely used for severe neuromuscular or paralytic scoliosis but is associated with substantial surgical trauma, blood loss, transfusion requirements, and perioperative morbidity. The minimally invasive approach uses limited posterior incisions, posterior instrumentation, and spinopelvic fixation with second sacral alar-iliac screws. The study will evaluate whether minimally invasive surgery provides comparable correction of pelvic obliquity and spinal deformity while reducing perioperative surgical burden, complications, hospital stay, and medical costs.
