Comparison of one-stage versus two-stage anteroposterior spinal fusion in pediatric patients with cerebral palsy and neuromuscular scoliosis.

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.
