    Abstract: A porous apparatus includes a first layer and a second layer. The second layer has a plurality of struts. At least some of the struts define a porous geometry defining a plurality of faces, at least one of the plurality of the faces at least partially confronting the first layer. Each face is bounded by intersecting struts at vertices. Less than all of the vertices of each face of the porous geometry at least partially confronting the first layer are connected by a strut to the first layer. A process of producing the at least partially porous structure includes depositing and scanning metal powder layers. At least some of the scanned metal powder layers form either one or both of a portion of a first section of the structure and a portion of a second section of the structure formed by at least the struts defining the porous geometry.

    Abstract: A system for bone resurfacing or total hip replacement, including an acetabular component having a first cavity, a dual mobility liner having a second cavity, the outer surface of the liner being configured to be received within the first cavity and articulable therein relative to the inner surface of the acetabular component and a femoral component having a head and a stem extending from the head and being configured to be received within a femur, an outer surface of the head being configured to be received within the second cavity. The dual mobility liner includes a plurality of openings that extend from an outer surface of the liner to an inner surface of the liner, such that the plurality of openings facilitate fluid communication between opposing sides of the liner.
