Abstract

An artificial bone generally includes a substantially continuous outer wall defining an inner cavity, an inner core disposed within at least a portion of the inner cavity, wherein the inner core includes a porous material having stiffness within a range of stiffness properties for mammalian cancellous bone and strength within a range of strength properties for mammalian cancellous bone, and a barrier layer disposed between the outer wall and the inner core to separate the outer wall from the porous material.
