摘要:目的探讨节段性骨缺损修复过程中,微量元素钙、锌、镁、铜含量变化的规律。方法取7只雄性新西兰大 白兔尺桡骨制成长1.5 cm脱钙骨基质、深低温冷冻骨、深低温冷冻脱钙骨基质84枚,之后进行不同的构建后分别移 植于40只同种大白兔双侧桡骨相同长度骨缺损处(随机分为四组,80肢共8组,其中10肢不移植任何材料作为空白 对照组),于术后l、2、4、8、12周各组分别杀死2只。于移植区取材进行X线、组织学切片、微量元素测定等检查,并对 结果行统计学分析。结果a)除空白对照组骨缺损未愈合外,其余各组均骨性愈合ob)骨缺损修复后第2周末。缺损区 钙、镁、锌达峰值,到第4周末钙、镁降至谷底,而锌仍维持峰值。然后三者共同上升,至第8周末均达第2个峰值。之后 钙、镁轻度下降,而锌轻度卜升。e)铜在骨缺损修复的头4周内一直稳定在低水平,之后开始轻度上升,8周末开始明 显I二升,至第12周末达其峰值。结论a)钙作为评价成骨活性大小的指标,取材应有时间限制;b)骨锌、镁值町能是有 用的评价骨缺损修复材料成骨活性的指标;它们值低,成骨活性高,值高则成骨活性低;c)骨铜值不宜作为评价骨缺损 修复材料成骨活性的指标。
