PurposeTo确定椎弓根螺钉放置在小于7岁的儿童中的可靠性，并评估椎弓根螺钉插入对椎骨和椎管进一步生长的影响。MethodsA回顾性研究了2003年1月至2010年12月在一个脊柱中心进行的35例小于7岁儿童先天性脊柱侧凸的连续患者。接受至少两个节段椎弓根螺钉内固定的患者，随访至少24个月。在内固定节段和相邻非内固定节段进行测量。椎弓根螺钉插入对进一步growth.ResultsThe手术的平均年龄为4.4年（53个月，范围，23-84个月）的影响进行了评价。35例患者的190个节段符合入选标准。77个节段没有螺钉，113个节段至少有一个螺钉。椎管及椎体参数的测量值术前与末次随访值比较有显著性差异（P< 0.001）。有无螺钉固定，椎体生长速度和椎管矢状径无显著性差异。在腰椎椎体的增长率均高于在胸椎的仪器和相邻groups. Conclusion椎弓根螺钉器械不会造成发育迟缓的影响，在儿童的椎体和椎管在早期的年龄。这是一种安全可靠的手术，可实现稳定的固定。
PurposeTo determine the reliability of pedicle screws placed in children younger than 7 years of age, and to evaluate the effect of pedicle screw insertion on further growth of the vertebra and spinal canal.MethodsA retrospective study of 35 consecutive patients through Jan 2003–Dec 2010 for congenital scoliosis in <7 years children was performed at one spine center. Patients undergoing pedicle screw instrumentation of at least two levels, which had been followed-up for at least 24 months were included. Measurements were performed in instrumented and adjacent non-instrumented levels. The effect of pedicle screw insertion on further growth was evaluated.ResultsThe average age at surgery was 4.4 year (53 months, range, 23–84 months). 190 segments in 35 patients met the inclusion criteria. 77 segments had no screws and 113 had at least one screw. There was a significant difference between the pre-operative and final follow-up values of the measurement of spinal canal and vertebral body parameters (P< 0.001). No significant difference existed between growth rates of vertebral bodies and the sagittal diameters of spinal canal with or without screws. The growth rates of vertebral bodies in lumbar spine were higher than in thoracic spine in both instrumented and adjacent groups.ConclusionPedicle screw instrumentation does not cause a retardation effect on the development of vertebral bodies and the spinal canal in children at an early age. It is a safe and reliable procedure to achieve a stable fixation.
