ObjectiveThe treatment of severe spinal deformities in pediatric patients is very challenging. Posterior only vertebral column resection (PVCR) allows for correcting of severe deformities of the vertebral column via a posterior only procedure. We analyzed radiologic outcome of PVCR performed on a series of pediatric patients with severe congenital and acquired spinal deformities.MethodsA case series of 11 pediatric patients with severe spinal deformity who were treated by PVCR between 2009 and 2013 were retrospectively analyzed. All patients had posterior instrumentation and reconstruction of the anterior column with titanium cages filled with autologous bone. Seven patients had pure kyphosis or kyphoscoliosis, whereas 4 patients were treated because of scoliotic deformities. The patient records were reviewed for demographic and general clinical data. Complications and adverse events, transfusion rates, and surgical time were recorded. Radiologic analysis included Cobb angles and percentage of correction, analysis of sagittal profile, time to fusion, and possible complications related to instrumentation.ResultsAverage preoperative scoliosis of 61° was corrected to 32°, resulting in a 50% correction at final follow-up. Coronal imbalance was improved to 36% at the most recent follow-up. Mean preoperative kyphotic deformity was 90° and was corrected to 43° at the last follow-up evaluation. Intraoperative complications included loss of the neuromonitoring signals in 2 cases and pleural laceration in 1 case.ConclusionsPVCR for children is an effective and safe technique providing a successful correction of complex pediatric spinal deformities. Nevertheless, it remains a technically highly demanding procedure, implying the possibility of severe complications.Copyright © 2017 Elsevier Inc. All rights reserved.
