摘要 目的探讨纳米羟基磷灰石/聚酰胺(n-HA/PA66)复合生物活性人工骨在颈椎双开门椎管成形术中的应用价值。方法脊髓型颈椎病11例,发育性颈椎管狭窄症7例,颈椎后纵韧带钙化症4例,术前JOA评分为(6.36±2.74)分。22例患者均行颈椎双开门椎管成形术,术中于劈开的棘突之间填充n-HA/PA66复合生物活性人工骨块。结果本组所有患者术后束带感明显缓解。22例随访时间12~25个月。末次随访时JOA评分为(14.23±3.47)分,与术前相比,P〈0.05。术后12个月CT扫描示颈椎管扩大良好,无"椎板关门"情况,n-HA/PA66复合生物活性人工骨块与棘突融合良好。结论 n-HA/PA66复合生物活性人工骨用于颈椎双开门椎管成形术术后显效快,无椎板"再关门"情况,人工骨块与棘突融合良好,近期疗效较好。
