The scaffold has a porous bone ingrowth area containing interconnected struts surrounded by a microporous shell. At the ends of the scaffold, the shell may be extended as a guide flange to stabilize the scaffold between ends of bone. The center of the scaffold may be empty and may serve as a potential marrow space.
