目的 综述骨膜在牵拉成骨过程中作用的研究进展.方法 广泛查阅近年来国内外有关骨膜在牵拉成骨过程中作用的文献,分析总结骨膜在牵拉成骨中的作用机制及其影响因素.结果 骨膜富含新骨生成所必需的各种细胞(MSCs、成骨细胞等)、微血管及各种生长因子等,为牵拉成骨过程中新骨的生成提供必要的细胞支持、营养物质支持及代谢调节,能显著促进牵拉成骨过程中新骨的生成.结论 骨膜在牵拉成骨过程中起着非常重要的作用.“,”Objective To review the research progress of the role ofperiosteum in distraction osteogenesis.Methods The related domestic and foreign literature about the role of periosteum in distraction osteogenesis in recent years was extensively reviewed,summarized,and the mechanism and influencing factors of periosteum during traction and osteogenesis were analyzed.Results The periosteum is rich in all kinds of cells (mesenchymal stem cells,osteoblasts,etc.),microvessel and various growth factors,which are necessary for the formation of new bone.It can promote the formation of new bone in the process of traction osteogenesis significantly.Conclusion The periosteum plays an important role in the progress of distraction osteogenesis.
