Abstract: The methods and compositions disclosed herein describes a solution containing at least one block co-polymer that is a liquid at lower temperatures and transitions to a gel at higher temperatures. The compositions are useful, for example, as an alternative to saline or silicone-gel as fillers for prostheses.

Abstract: The present invention provides a composite implant comprising pores of a porous structure filled with a biodegradable magnesium-based alloy. Further, the present invention provides a composite implant which filles pores of the porous structure prepared by a metal, a ceramic or a polymer with a biodegradable magnesium-based alloy. Mechanical properties of the composite implant of the present invention are improved because a magnesium-based alloy filled in its pores increases the strength of a porous structure comprised of a metal, a ceramic or a polymer. Further, it can be expected that the magnesium-based alloy filled in the porous structure is decomposed in a living body, thus increasing bone formation rate. Accordingly bone tissue can be rapidly formed because the composite implant of the present invention has high strength and excellent interfacial force between the composite implant and bone tissue, compared to conventional porous materials.
