A skeletal implant for replacing a human bone includes an inner reinforcing member and an outer plasticized and fluid resistant layer encasing the inner reinforcing member. A structurally rigid and foamable layer is disposed between the inner reinforcing member and the outer plasticized layer. An end of the outer layer is configured for receiving, in articulated engagement, an end of an adjoining bone. A plurality of ligaments are grafted between the implant and the adjoining bone and proximate the articulated engagement. Conduit passageways are also established between the inner reinforcing member and the end of the outer layer in order to communicate a fluid to an articulating engagement and ligament supporting location with an adjoining bone.
