经寰枢椎椎弓根钉内固定治疗儿童寰枢椎难治性脱位

目的 探讨应用后路经寰枢椎椎弓根螺钉固定融合治疗儿童难治性脱位的临床疗效.方法 2002年6月-2007年1月,对7例寰枢椎难治性脱位的患儿采用后路经寰枢椎椎弓根螺钉固定,同时辅以寰枢椎间植骨.结果 7例患儿寰枢椎脱位得到复位,无并发症发生,随访8～14个月(平均10个月),影像学显示患儿均获骨性融合.结论 经后路寰枢椎椎弓根螺钉固定融合术是一种有效的治疗儿童寰枢椎难治性脱位的方法.

Treatment of intractable atlantoaxial dislocation with atlantoaxial pedicle screw instrumentation in children

Objective To explore the clinical effects of atlantoaxial pedicle screw instrumentation in treatment of intractable atlantoaxial dislocation in children. Methods A total of 7 patients with intractable atlantoaxial dislocations were treated with aflantoaxial pedicle screw instrumentation plus atlantoaxial bone grafting from June 2002 to January 2001. Results The dislocation in all patients reached complete reduction, with no complications. All patients were followed up for average 10 months (8-14 months). Radiographs showed successful bone fusion in all patients. Conclusion Atlantoaxial pedicle screw fixation and fusion is an effective method for treatment of intractable atlantoaxial dislocation in chil dren.
