摘要 目的探讨应用零切迹即刻锚定颈椎动态融合器(AVS)治疗单节段颈椎间盘突出症的疗效。方法 20例单节段颈椎椎间盘突出症患者,均行颈椎前路减压后行AVS Anchor-C椎间融合固定系统治疗。观察患者术中损伤情况、出血量,手术时间以及术后吞咽障碍等并发症发生情况,术后脊髓、神经的恢复情况,观察内植物及植骨融合情况。结果手术顺利完成,无神经血管损伤,无一例感染,术中出血量50~100 ml,平均术中出血量为(60.5±10.4)ml,手术时间为35~60 min,平均手术时间为(45.2±8.4)min。术后1例出现吞咽障碍,予以观察治疗7 d后好转。术后3个月时患者颈椎曲度较术前明显改善,脊髓及神经功能较术前不同程度改善。CT证实已达到骨性融合平均(6.2±1.7)个月。动力位X线片显示AVS Anchor-C椎间融合固定系统固定稳定,无下沉、松动、断裂情况。结论应用AVS Anchor-C椎间融合固定系统治疗单节段颈椎间盘突出症疗效满意。它操作方便,能够维持生物力学稳定性、促进椎间融合率、减少临近节段的退变、对周围组织损伤小,且明显减少了术后吞咽障碍的发生率,降低了内固定植入的相关并发症,疗效满意。
