Abstract： 目的:探讨相邻双节段颈椎人工椎间盘置换术后颈椎曲度及临床功能的变化.方法:2004年4月-2007年1月收治因颈椎病行相邻双节段颈椎人工椎间盘置换术患者23例,其中使用Bryan人工椎间盘17例,术前颈椎曲度不良12例:使用Prodisc-C人工椎间盘6例,术前颈椎曲I度不良4例.统计并分析患者术前和术后3、12及24个月时颈椎运动范围、颈椎中立位曲度、手术节段Cobb角、手术节段是否发生异位骨化、手术邻近节段是否发生退变、术后Odom评分、JOA脊髓功能评分及颈肩痛VAS评分.结果:术后3、12及24个月时患者的颈椎活动范围、颈椎中立位曲度、手术节段Cobb角与术前比较无显著性差异(P＞0.05).术前颈椎曲度不良的患者使用Bryan人工椎间盘置换后局部后凸加重(P＜0.05);而使用Prodisc-C者得到改善(P＜0.05).所有患者的Odom、JOA和VAS评分较术前改善明显(P＜0.05).2例患者术后出现手术节段的异位骨化,1例出现邻近节段椎间盘退变.结论:相邻双节段颈椎人工间盘置换术基本保留了颈椎的曲度和运动功能,Prodisc-C颈椎人工椎间盘对曲度不良患者有一定的矫正作用.
