ABSTRACT:
Composite materials useful as hard tissue prosthetics comprising synthetic biodegradable polymers and unsintered calcium phosphate biomaterials optionally porositized by pore-forming agents are described. The composite materials may be ground and blended with a compatible water soluble pore-forming agent and then molded to form dense, shaped objects which may be made porous by leaching out said water soluble pore-forming agent. The composites may be used as hard tissue prosthetics either alone or in conjunction with conventional prostheses.
