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.
