Disclosed herein is an acellular bone graft and an artificial implant assembly comprising the same for repairing a bone defect of a subject in need. The acellular bone graft has a three-dimensional (3-D) body characterized in having at least one coupling part formed on at least one surface of the 3-D body, wherein the coupling part has a structure that matches that of another coupling part of another acellular bone graft. The artificial implant assembly comprises at least two acellular bone grafts of the present aspect, wherein each acellular bone graft is connected to each other via joining the coupling parts respectively having matching structures that allow the coupling parts to be tightly joined.本揭示內容是關於一種去細胞骨移植物,以及包含該去細胞骨移植物的人工移植組件,以修復一亟需個體之骨缺損。去細胞骨移植物具有一三維本體,其特徵在於,具有從該三維本體之至少一表面形成的至少一耦合件,其中該耦合件具有一結構,可與另一去細胞骨移植物之另一耦合件的另一結構對應。人工移植組件包含本揭示內容的至少二去細胞骨移植物,其中各該去細胞骨移植物藉由結合該耦合件以彼此連接,該耦合件分別具有可使該耦合件緊密結合的對應結構。
