摘要(Abstract)：

[目的]将可注射性羟基磷灰石/壳聚糖人工骨与自体骨移植用于修复兔股骨缺损,通过动物实验观察对骨缺损的修复作用。材料:新西兰健康成年大白兔24只,4个月龄,体重1.5～2.0 kg,雌雄不限。[方法]24只成年新西兰大白兔双侧股骨外侧髁均建立骨缺损模型,随机分为3组。(A)实验组:植入nHA/CS材料;(B)对照组:缺损处植入自体髂骨;(C)空白组:骨缺损旷置,不植入任何材料。术后第8、12周末取材,对实验组及对照组进行X线及组织学观察。并对8周、12周末标本缺损修复区行X线评分,实验组和对照组之间进行比较,评估该复合材料对骨缺损的修复效果。[结果]24只兔均进入结果分析,X线片检查实验组与修复疗效较满意,12周末组织学检查实验组有明显新骨形成。X线评分显示实验组与自体骨移植组比较,差异无统计学意义(P>0.05)。[结论]在促进骨缺损的修复中,新型可注射性nHA/CS骨修复材料能明显促进兔股骨骨缺损的修复,与自体骨移植比较差异无统计学意义。新型可注射性nHA/CS骨修复材料具有确切的骨缺损修复能力,有良好的应用前景。
