Abstract

目的 探讨自体或深低温冷冻同种异体微小颗粒骨复合胶原、骨形态发生蛋白(BMP)修复节段性兔桡骨缺损的效果.方法将兔自体或同种异体骨研磨成微小颗粒,分别与BMP及Ⅰ型胶原复合,并采用兔桡骨干1.5cm缺损的动物模型,通过X线、组织学、骨密度、生物力学等检测手段,与自体微小颗粒骨复合胶原修复节段性骨缺损的疗效比较.结果自体或深低温冷冻同种异体微小颗粒骨复合BMP胶原比自体微小颗粒骨复合胶原成骨效果优良,其中复合BMP组在8周即可使骨缺损修复,髓腔通畅,在骨缺损修复各时期,其成骨速度及成骨量均好于未复合BMP组.结论自体或深低温冷冻同种异体微小颗粒骨复合胶原BMP均可有效地修复节段性骨缺损,两种方法促进新骨形成无明显差异,异体微小颗粒骨复合胶原BMP是良好的骨缺损修复材料。
