摘要 [目的]评价复合可诱导DBM的同种异体骨垫在颈椎前路融合术中的临床疗效。[方法]在12例(男6例,女6例)行颈椎前路减压椎间融合患者中,应用自行研制的复合可诱导DBM同种异体骨垫作为融合介质,融合14个节段,其中外伤性颈椎不稳10例,脊髓型颈椎病2例。根据术前术后椎间隙高度、颈椎前凸Cobb角、JOA评分、融合时间、体温变化及伤口愈合情况,分析评价临床疗效。[结果]患者术后即刻椎间隙高度、颈椎前凸角、椎间前凸角与术前比较,差异均有统计学意义(P<0.05),而末次随访时与术后即刻比较,差异无统计学意义(P>0.05)。X线片及CT示所有病变椎间隙均达到骨性融合,平均融合时间3.8个月,动态照片未见假关节形成,无神经系统并发证,无融合骨垫以及钢板的移位,椎体无塌陷,切口无感染,JOA评分术后改善率为61%。[结论]复合可诱导DBM的同种异体颈椎融合骨垫(spacer)力学强度好,可辅助维持颈椎的生理弧度和椎间隙的高度,促进椎间隙的骨性融合,提高融合率,是一种理想的颈椎前路融合器。
