Abstract

目的 分析寰枢椎经关节螺钉治疗寰枢椎不稳定患者的手术疗效和安全性,并探讨提高安全性的措施.方法 对2000年3月~2004年12月行寰枢椎经关节螺钉固定术的23例上颈椎损伤患者进行随访,了解术后寰枢椎融合的情况,比较手术前后颈痛的VAS评分变化,了解椎动脉损伤和其它并发症的发生情况.结果 所有患者平均随访32.1个月,融合率为91.3%;术前CT发现有3例患者(13.0%)单侧椎动脉高跨;有1例患者出现单侧椎动脉疑似损伤;颈痛VAS评分由术前平均8.3分,随访时为3.2分,差异有显著性意义(P<0.05).结论 使用寰枢椎经关节螺钉治疗寰枢椎损伤融合率高,疗效满意,在术前进行CT重建排除解剖异常、设计个性化的最佳进钉点和进钉途径可最大程度地减少椎动脉损伤的可能。
