     摘要：[目的]观察异体楔形骨块在双开门扩大成形术中的应用效果。[方法]2003年4月～2004年6月，22例患者使用预制异体楔形骨块行棘突纵割式椎板扩大成形术。术后随访16～30个月，平均184个月。术前术后采用JOA评分了解脊髓功能状态，X线片和CT了解颈椎活动度(ROM)和植骨融合状况。[结果]末次随访时，JOA评分由术前(83±26)分改善至(133±31)分；颈椎ROM由术前(413±108)°下降至(234±87)°，未见术后颈椎失稳；679%异体骨块与棘突完全骨性融合，232%部分骨性融合，89%骨块部分吸收，未融合；未见骨块破裂和移位。[结论]使用异体楔形骨块的双开门扩大成形术是一种安全有效的手术方法。
