文题释义:
骨缺损:指骨的结构完整性被破坏,是临床常见病。典型的缺损局部临床表现,结合X射线检查,即可明确诊断。较小的骨缺损(通常指8 mm以下),对于一个健康的非吸烟者来说,有可能自行愈合;但骨缺损过大,或者是在较小的骨头上的骨缺损,很难完全愈合。这就需要手术的干预。
异体骨来源:同种异体骨来源于其他人的骨,大多数都是从尸体中获取或者募捐获得;异种异体骨大多来源于动物的骨组织。
 
 
背景:由于感染、肿瘤、先天性疾病等原因所致骨缺损修复始终是骨科医师面对的难题,其中大部分不能自身愈合,因此产生了骨移植修补的需要。自体骨由于具有良好的骨传导性、骨诱导性及骨生成作用,在临床应用最为广泛,但其使用受许多条件限制。支架材料作为骨组织工程的核心部分,其生物学结构、功能等备受关注。骨组织工程支架以及修补材料还广泛应用于整形外科、神经外科、口腔手术等其他领域。
目的:综述骨修复及支架材料的研究进展。
方法:由第一作者用应用计算机检索 2006至2016年CNKI数据库(医学版)和外文生物医学期刊整合系统中有关骨移植支架材料与骨缺损修复方面的文献。

结果与结论:材料科学和分子生物学等多学科的快速发展,多领域的交叉融合和三维技术的日益成熟,纳米细胞基因工程等技术的使用,复合型骨移植材料有着更广阔的前景。尽管各类骨移植材料品类繁多,但各有优缺点。临床治疗骨缺损,尤其大量或节段性骨缺损,急需要一种适宜的修复材料,作为最有潜力的异种骨移植,尚需进一步研究来评价其临床安全性及有效性。

Abstract:

BACKGROUND: It is always a difficult problem for orthopedic surgeons to repair a bone defect caused by infection, tumor or congenital diseases. Most of these defects cannot heal without any aid of bone transplantation. Autogenous bone has been widely used in clinic because of its good bone conduction, bone induction and bone formation, but its use is limited by many conditions. As the core part of bone tissue engineering, scaffold materials have attracted much attention in the physical structure and function. Bone transplantation has also been widely used in plastic surgery, neurosurgery, and oral surgery.

OBJECTIVE: To review the progress of bone repair materials.
METHODS: The first author retrieved literatures on bone graft materials and bone defect repair published during 2006-2016 in CNKI (Medical Edition) database and Foreign Medical Journals Full-Text Service.

RESULTS AND CONCLUSION: With the rapid development of multi-disciplinary disciplines, such as material science and molecular biology, multi-disciplinary integration and three-dimensional technology, and the application of nano-cell genetic engineering, composite bone graft materials have a broad prospect. A variety of bone graft materials with different merit and demerits have been developed. A proper repair material is necessary and urgent for the clinical treatment of bone defects, especially large or segmental bone defects. As for the most potential xenogeneic bone graft, further research is warranted to evaluate its clinical safety and effectiveness.
