摘要： Aspects of the present disclosure relate generally to preparing models of three-dimensional structures. In particular, a model of a three-dimensional structure constructed of porous geometries is prepared. A component file including a porous CAD volume having a boundary is prepared. A space including the porous CAD volume is populated with unit cells. The unit cells are populated with porous geometries having a plurality of struts having nodes on each end. The space is populated with at least one elongated fixation element extending beyond the boundary to produce an interlocking feature enabling assembly or engagement with a mating structure.

摘要： A method for removing a stem portion of an orthopedic implant from a bone comprises exposing an implanted orthopedic implant having a body portion, a stem portion interconnected to the body and a porous metal section forming an interconnection between the body and the stem portion. A cutting tool is mounted on a holder connected to an exposed surface of the orthopedic implant. The porous section is aligned with the cutting tool mounted on the holder. The entire porous section is cut by moving the cutting tool therethrough in a direction transverse to the stem portion axis. The implant body portion is then removed and then the stem portion is removed from the bone. The cutting tool may be a saw or chisel which may be mounted on a guide fixed to the body portion.

摘要： A tibial implant system has an ultra-high molecular weight polyethylene tibial insert which can engage with either one of two tibial trays through differing means of engagement. The tibial insert includes a locking wire and locking tab disposed along an anterior surface and a locking recess disposed along a posterior surface. A first polymeric tibial tray includes a bead along an anterior wall and an undercut area along a posterior wall. A second metallic tibial tray includes a plurality of barbs along an anterior wall and an undercut area along a posterior wall.
