When a bone fracture is unable to heal because of extensive bone loss, bone grafts are used. Synthetic bone grafts such as injectable calcium phosphate cement (CPC) are an interesting alternative for donor bone from the patient since these do not involve an extra surgical site and are unlimitedly available. CPC should be replaced by newly formed bone to regain function and stability. Degradation of CPC takes place when the surface of the CPC is able to interact with bodily fluids and cells can penetrate the cement. Unfortunately, the pores in CPC are too small for cell penetration. Creating an interconnective network of macropores by adding fast degrading or dissolving materials to CPC is essential. This thesis showed the great potential of a novel approach that leverages simple material properties to generate completely degradable, injectable CPCs with distinct bone regeneration profiles.
