摘要： A femoral component for a hip prosthesis has a distal portion defining a central longitudinal axis. The component has a generally conically shaped mid-shaft portion and a proximal portion with a shape based on the reamer and a shaped chisel used by the surgeon to prepare the proximal metaphysis and medullary canal. The proximal portion is shaped in a manner wherein a cross-section taken perpendicular to the central axis has a medial side formed as a first circular arc, a comer of the cross-section formed by the posterior and lateral sides as a second circular arc with a center on the central axis. The posterior side is arcuate and concave and tangent to the first and second circular arcs, with the anterior side being arcuate and convex.

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.

摘要： A method of preparing a computer-generated model of a three-dimensional structure constructed of porous 5 geometries is disclosed. 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 10 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. The disclosure extends to a method of producing a three-dimensional structure and a tangible 15 computer-readable storage medium on which computer readable instructions of a program are stored. The instructions, when executed by a processor, perform a method of preparing a computer-generated model. prepare a 3& CAD modtel of the construct w h dfernties for porous and soli prt - 610 6 reate a bounding box which completely icpsu-ates the porous file arnd-ulat ---- 620 with unit cel s Separate the unit cels into tw3is of ces0 that uass the surface and cells that don t 660- Populate the M s hat r 3 h o the cel s which don t cross the porous geome suace determine if these are inside -- 640 or outsidete structure Use one of the flowing populate the unt cells with wth oper anions on the surface porous geometrics - 650 Clip to surface Clip to node Create a confrma surface 1-690 -- ---- - -i- -- - -- - - -- - - - - Z ------ Remove ever part o Remove every s u Determnewhich struts intt the struts whiha taAt cuts t e on the otsie of the pa 4 6I outside the surface back to the last node r keep every strut that reaks the surface to the outside noe Moe the outside node to su race or remove depending 692 the level of deformation to the struts involved
