Abstract
After resection of malignant bone tumors, large bone defects should be reconstructed to restore the function of the affected limbs. The main options for reconstruction include autogenous bone grafts, allogeneic bone grafts and endoprosthesis
Autogeneous bone grafts may be vascularized ; vascularized bone autograft operations are now performed widely as a result of the development of microsurgery. As blood flow can be preserved and the cells in the grafted bone remain alive, bone formation and bone fusion are vigorous.
This technique has generated remarkable improvement in therapeutic success rates (1). Because of the limited amounts of bone that can be collected, however, it is sometimes difficult to repair large bone defects; in such cases, allogeneic bone grafts or endoprosthesis is indicated.
Allograft are a form of reconstruction utilizing dead bone.
