摘　　要：本义通过生物力学测试、双硫蓝血管灌注、连续荧光标记等方法观察了解大段皮质骨髓腔内移植的作用和自然转归，证明植骨６～１２周血运完全恢复，１２～２４周被新骨取代并与宿主骨愈合。髓内植骨主要起固定作用，随着骨愈合的完善，它的固定作用由最初的单纯机械固定逐渐转变为生物固定。它还是理想的“生物降解材料”。证明大段皮质骨髓腔内移植在进行骨结构重建时具有其独特的作用和优越性。AbstractUsing biomechanical tests. blood perfusion with disulphine blue and polychromatic sequential labeling,the authors observed the action of intramedullary cortical bone grafting and its natural progressing morphology. The results showt1d that blood circulation was entirely recovered in 6～12 weeks after bone grafting and in 12～24 weekxnew bone developed and the grafted cortical bone healedwith the host bone.The intramedullary grafted bone mainly played a role of fixation, With the progress of bone healing,the fixation action turned gradually from simple mechanical to bio-fixation.The result showed that the method of intramedullary grafting of large piece of cortical bone has a distinguished feature and advantages in treating bone defect and in the process of bone structure reconstruction.
