经寰枢椎椎弓根侧块螺钉技术治疗寰枢椎失稳

目的 探讨应用寰枢椎椎弓根侧块螺钉技术治疗寰枢椎失稳的疗效. 方法 2006年6月-2007年12月,采用寰枢椎椎弓根螺钉技术治疗寰枢椎失稳11例,回顾性分析临床效果. 结果 术后X线显爪所有螺钉位置良好,寰枢椎复位满意.术后随访3～21个月,平均12个月,本组患者均未发生脊髓损伤或椎动脉损伤,未出现内置物断裂. 结论 使用寰枢椎椎弓根侧块螺钉技术治疗寰枢椎失稳操作简便,固定牢固,疗效可靠.

Treatment of atlantoaxial instability with atlantoaxial pedicle and lateral mass screw WANG

Objective To study the effect of atlantoaxial pedicle and lateral mass screw in treat-ment of atlantoaxial instability. Methods A retrospective analysis was done on 11 eases of aflantoaxi-al instability treated with atlantoaxial pedicle and lateralmass screw from June 2006 to December 2007. Results The postoperative radiographs verified good position of all screws, with satisfactory atlantoaxial reduction. Follow-up for 3-21 months (average 12 months) showed no spinal cord and vertebral artery in-jury or interfixation failure. Conclusion Atlantoaxial pediele and lateral mass screw technique is a convenient method with solid fixation for treatment of atlantoaxial instability.
