摘要
目的探讨寰枢椎不稳经后路椎弓根螺钉固定融合手术治疗的方法及临床疗效。方法对15寰枢椎不稳的患者应用直视下椎弓根钉固定并行自体髂骨植骨融合。结果 15例60枚螺钉均成功植入,复位固定满意,全组病例未发生椎动脉、脊髓损伤,术后临床症状得到不同程度的改善,所有患者均获得6~24个月随访,平均7.5个月;患者均在3~6个月寰枢椎骨性融合,未发现螺钉松动、断裂现象。结论直视下寰枢椎椎弓根螺钉植入技术具有置钉相对安全、准确、融合率高等特点,是治疗寰枢椎不稳的一种有效手术技术。
ObjectiveTo explore the way and clinical outcomes ofpedical screw internal fixation and fusion for the treat- ment of atlantoaxial instability. Methods 15 patients with upper cervical instability were treated by direct vision internal fixation and reduction with transatlantoaxial pedicle screw-rod and bone graft fusion. Results 60 pedical screws were im- planted successfully. No complications were found in the operation on the 15 patients and after the followed up period of 6-24 months. The neurologic symptoms were improved. No breakage or loosening of screw and rob occurred. All patients achieved a solid bone fusion after 3-6 months. Conclusion The direct vision pedical screw internal fixation and fusion is an safe and effective method for the treatment of atlantoaxial instability.
