Abstract Background: The use of pedicle screws in thoracic or lumbar spinal fusion and deformity correction is becoming more privalent, even in children. Improper screw insertion can produce major complications. The accuracy of the screw placement is evaluated post operatively by CT scanning in a small group of children.Methods: In a cross section study, 7 children under 5 years of age who had undergone spinal surgery, using pedicular screws were evaluated in two training hospitals in Tehran, Iran. The position of pedicular screws was determined by an expert radiologist and documented along with probable neurovascular effect.Results: Seven children with total of 42 pedicle screws were assessed. 34 screws (80%) had been placed in the desired positions. The remaining 9 screws had produced minor breakage through the cortices, mainly in narrow thoracic pedicles. There was no case of neurovascular compromise, or stability problem in the 42 screws.Conclusions: Use of peducular screw in spinal fusion of young children is a proper technique.

Abstract Background: Hemivertebra is one of the common causes of congenital scoliosis. In cases with curve progression, resection of the hemivertebra through a combined anterior and posterior approach (CAPA) is one of the usual treatment modalities which is associated with high morbidity. Recently, hemivertebra resection through a posterior only approach (POA) is introduced. In the current study, we are reporting our experience with a single posterior approach. Methods: Ten patients with lumbar CS who had undergone hemivertebra resection through a POA with transpedicular instrumentation and short segment fusion, between 2009 and 2012 were retrospectively studied. The main and the compensatory scoliotic curves and kyphotic curves were measured and compared before surgery and by the 16.1±10 months follow-up. Results: Fusion was obtained in all of the patients. The mean drop in the main, compensatory and kyphotic curves were 39.6±6.6 to 11.3±5 degrees, 12.9±5.1 to 7.8±3.4 degrees and 15.6±8.1 to 2.7±8.2 degrees, respectively (p < /i>
