This was a retrospective review of 223 consecutive cases (1986-1996) from one institution where 759 thoracolumbar and lumbar pedicle screws were used in the treatment of various pediatric spinal disorders in patients less than 18 years of age.
To determine the incidence of short- and long-term (> 2 years follow-up) complications in this group of patients-specifically, complications related to instrumentation and those directly attributable to pedicle screws in these pediatric patients.
Although much has been written regarding the use of pedicle screws in the adult population, no published study has examined complication rates with regard to thoracolumbar and lumbar pedicle screws placed for pediatric spinal disorders.
A retrospective review of 223 consecutive cases involving 759 pedicle screws placed for a variety of pediatric spinal disorders was performed. Complications were divided into short term and long term (> 2 years follow-up) and into those relating to instrumentation and those relating to pedicle screws specifically.
Short-term complication occurred in 5 patients (2.2%) for a total of 17 screws ultimately removed. Only two of these patients had screws removed for lumbar radicular complaints. No residual sequellae resulted. No long-term (> 2 years postoperative) complications were noted.
Low short- and long-term complication rates specific for pediatric pedicle screws suggests that for properly trained spinal surgeons, pedicle screws fixation in the pediatric population can be performed safely to treat a variety of spinal disorders.
这是一项对某机构223例连续病例（1986 - 1996年）的回顾性研究，其中759枚胸腰椎和腰椎椎弓根螺钉用于治疗18岁以下患者的各种小儿脊柱疾病。
确定该组患者短期和长期（随访超过2年）并发症的发生率，特别是与器械相关的并发症以及这些小儿患者中直接归因于椎弓根螺钉的并发症。
尽管关于成人使用椎弓根螺钉已有大量文献报道，但尚无已发表的研究探讨用于小儿脊柱疾病的胸腰椎和腰椎椎弓根螺钉的并发症发生率。
对223例连续病例进行回顾性研究，这些病例共置入759枚用于各种小儿脊柱疾病的椎弓根螺钉。并发症分为短期和长期（随访超过2年），以及与器械相关的并发症和专门与椎弓根螺钉相关的并发症。
5例患者（2.2%）发生短期并发症，最终共取出17枚螺钉。其中只有2例患者因腰椎神经根症状而取出螺钉。未遗留后遗症。未观察到长期（术后超过2年）并发症。
小儿椎弓根螺钉特有的短期和长期并发症发生率较低，这表明对于训练有素的脊柱外科医生而言，在小儿患者中进行椎弓根螺钉固定可安全地用于治疗各种脊柱疾病。
