[The vascularized bone transplant for the bridging of large bond defects].

Vascularised autogenous bone transplants are superior in reconstructing large segmental bond defects. We refer to the results of our experimental investigations comparing autogenous knee joint transplantations with and without microvascular anastomoses. It could be shown that vascularised bone transplants can bridge large bone defects with intact form and shape within one year. Without primary vascularisation creeping substitution results in many complications and successful filling of the defect needs several years. Clinical results are analogous.
