Abstract
Objective: To evaluate the outcomes and complications of one-stage and two-stage combined anterior-posterior spine fusion, and to document which procedure is more efficacious and provides better results.
Study Design-Material: A retrospective study was performed including 45 pediatric patients with spastic quadriplegic cerebral palsy and neuromuscular scoliosis who underwent anterior-posterior spinal fusion.
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 anterior-posterior 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> .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.
Conclusions: 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. Since this study cannot separate risk based on disease severity, staging the procedures on different days is likely more important in individuals with very large curves and concomitant medical illness.
