摘　　要：目的探讨经后路寰枢椎椎弓根螺钉内固定治疗创伤性寰枢椎不稳的可行性及临床疗效。方法 2007年5月～2010年3月间我科收治的15例创伤性寰枢椎不稳患者,应用经后路寰枢椎椎弓根螺钉固定融合术治疗,观察术后并发症情况及近期疗效。结果手术时间2～3 h,术中失血量200～400ml,未出现螺钉置钉相关的血管、神经损伤等并发症,术后随访未出现内固定松动、脱落或断裂,术后平均6～8月寰枢椎获得骨性融合。结论经后路寰枢椎椎弓根螺钉固定是治疗创伤性寰枢椎不稳的有效方法。Objective To explore the feasibility and clinical outcome of posterior transpedicular screw internal fixation in both atlas and axis for traumatic aflantoaxial instability. Methods 15 cases with traumatic atlantoaxial instability were treated by posterior transpedicular screw intemal fixation in both atlas and axis combined with bone graft fusion in our hospital between May 2007 and March 2010. The early outcome and complications were analyzed. Results The average operative time had ranged from 2 to 3 hours. The average operative blood loss had ranged from 200ml to 400ml. No spinal cord and vertebral artery injury had happen. No intemal fixation loosening or breakage had happen in all the cases. The average interbody fusion time averaged 6 - 8 months postoperative. Conclusion The Posterior transpedicular screw internal fixation in both atlas and axis is an effectivemethod for the treatment of atlantoaxial instability.
