Claims13
A sliceable composite bone repair material comprising:
- a porous block-shaped scaffold comprising a bone substitute material comprising a synthetic ceramic material, and wherein said scaffold comprises interconnected macropores;
- and
- a stabilizing polymer disposed therein, wherein the stabilizing polymer is a degradable polyethylene glycol hydrogel formed by a cross-linking Michael-type addition reaction of at least two precursor molecules, wherein said cross-linking reaction forms an ester linkage between the at least two precursor molecules, and
- wherein said hydrogel is degradable in water.
