Abstract
INTRODUCTION: Surgery for pediatric spinal deformity may involve vertebral osteotomies in complex cases. Vertebral column resection (VCR) is the most technically demanding procedure, with the severest morbidity. It can use a double anterior and posterior approach (APVCR), though a single posterior approach (PVCR) is gaining in popularity. HYPOTHESIS: PVCR provides effective correction with acceptable morbidity in children. METHOD: A single-center retrospective series included spinal deformities treated by PVCR. Surgical data and global pelvic-spinal balance parameters were analyzed. RESULTS: Sixteen PVCRs were performed in 13 patients, with a mean age of 14.1±2.8 years. Mean operative time was 411±54minutes. Mean preoperative rigid principal Cobb angle was 74.3°. Mean correction was 64.3% postoperatively, without significant correction loss at last follow-up. Mean blood loss was 941±221ml. The cell-saver enabled 92.3% autologous transfusions, with 53.4% homologous transfusions. Transient monoplegia and permanent psoas deficit were observed during the postoperative period. Radiologic follow-up found 4 non-unions requiring revision. CONCLUSION: PVCR provided major correction of rigid spinal deformity in children. Complications mainly comprised mechanical or neurological incidents. LEVEL OF EVIDENCE: IV, non-comparative cohort study.
