Abstract

STUDY DESIGN: A retrospective study was performed including 45 pediatric patients with spastic quadriplegic cerebral palsy and neuromuscular scoliosis who underwent anteroposterior spinal fusion. OBJECTIVES: To evaluate the outcomes and complications of one-stage and two-stage combined anteroposterior spine fusion and to document which procedure is more efficacious and provides better results. SUMMARY OF BACKGROUND DATA: Circumferential spinal arthrodesis has been proven to achieve better scoliotic curve correction, decreasing significantly the risk of pseudarthrosis and progression of the deformity. There have been a few studies comparing same-day versus staged anteroposterior spinal surgery in mixed populations with neuromuscular scoliosis, but not in an isolated group of pediatric patients with spastic cerebral palsy. METHODS: The medical records and radiographs of all patients were reviewed, and the results were statistically analyzed. The complications were divided into medical, subcategorized into major and minor, and technical. RESULTS: There was no statistically significant difference (P > 0.05) between one-stage (Group 1) and two-stage (Group 2) patients, considering age at surgery, preoperative scoliosis angle, pelvic obliquity, kyphosis angle, lordosis angle, levels of anterior release, percentage of scoliosis correction, radiographic follow-up, hospitalization time, and intensive care unit stay. Sequentially performed spinal procedures (Group 1) were associated with increased intraoperative blood loss, prolonged operative time, and a considerably higher incidence of medical and technical complications, including two perioperative deaths. CONCLUSION: Two-stage anteroposterior spinal fusion provides safer and more consistent results with several advantages over the single-stage procedure in the management of patients with cerebral palsy and neuromuscular scoliosis.
