In the case of bone defects, there are two different methods to close such defects. One option is to use bone autografts, but therefore the bone graft has to be cut off from the same person’s hip. In this case the patient has to undergo an additional surgery, which bears complications, like causing inflammations. Absorbable, open-pored implants minimizes these risks. Synthetic bone implants are typically made of ceramic, bioglass or polymers. In this study, magnesium alloys are investigated as absorbable porous bone substitute materials in which the bone can grow into. The main advantages are the design flexibility to cast individual implants by investment casting and mechanical properties similar to the bone. Moreover, to meet the mechanical requirements, simulations of the sponge structure and compression tests are applied. In order to adapt the degradation behavior to the bone’s ingrowth behavior, the implant material has to be alloyed and coated.
