Abstract
Stress-bearing prostheses for replacement or partial replacement of stress-bearing bone are fixed in place by bony ingrowth by providing a stress-bearing member having a porous region in combination with an osteogenic factor extract or a purified osteogenic inductive protein, optionally in combination with a TGF-beta cofactor, in a pharmaceutically acceptable carrier. The carrier is preferably either a collagen composition or a ceramic.
