- W3029565524 abstract "目的 研究复合骨形态蛋白-2的聚乳酸-乙醇酸共聚物/磷酸三钙(PLGA-TCP-BMP-2)人工骨结合自体带血供尺骨骨膜移植修复大段骨缺损的效果. 方法 手术造成30 mm绵羊桡骨骨缺损,A组植入PLGA-TCP-BMP-2人工骨及带血运的尺骨骨膜,B组仅植入PLGA-TCP-BMP-2人工骨,C组不植入任何材料.3组均以钢板固定骨缺损区.术后24周拍摄X线片并处死动物,进行组织学观察评价. 结果 X线检查示A组桡骨缺损处完全成骨修复,皮质骨与髓腔的轮廓清晰；B组亦完全修复,但新生骨密度及髓腔轮廓清晰度均不如A组；C组无有效骨痂形成.组织学检查示A、B组骨痂外层形成为板层骨,C组缺损区可见大量纤维组织填充. 结论 PLGA-TCP-BMP-2人工骨结合自体带血供尺骨骨膜移植能够很好的修复绵羊桡骨30 mm的骨缺损。" @default.
