摘要:
A prosthesis includes an implant defining an attachment surface thereon. A porous insert is selectively coupled to the implant. The porous insert is adapted to be received at the attachment surface of the implant in a retained position. The porous insert is adapted to facilitate tissue ingrowth. In one embodiment the implant comprises a femoral component. The femoral component comprises an inner condylar portion having a first and second lateral sidewalls, an anterior wall and a posterior wall defining a box. The box defines the attachment surface. In other embodiments, the implant comprises a hip stem and an acetabular shell.

A prosthetic system for replacement of a portion of a hip bone including a plurality of acetabular components and a plurality of flange components. The prosthetic system also includes a plurality of pubis components. Each of the pubis components and each of the flange components are operable to connect to each of the acetabular components. Each of the pubis components define a clamping portion that is configured to attach to an opposed healthy pubis bone. An angle between the flange component and the pubis component varies among the acetabular components.

An intramedullary fixation device and associated method. The intramedullary fixation device includes a first intramedullary component having a first bone-attachment end and a first elongated member, a second intramedullary component having a second bone-attachment end and a second elongated member, and a compliant member coupling the first and second intramedullary components for applying bone-compressing stress. The second intramedullary component defines a sleeve such that the first elongated member can pass therethrough.

A patellar implant includes a posterior portion and an anterior portion. The posterior portion may define an articulating surface and a first retaining feature. The anterior portion may define a tissue engaging portion and a second retaining feature adapted to advance into a mechanical interlock with the first retaining feature in an assembled position. The mechanical interlock between the first and second retaining features may cooperate to resist separation of the posterior and anterior portions in the assembled position.

Privacy-sensitive methods, systems, and media for targeting online advertisements using brand affinity modeling are provided. In accordance with some embodiments, a method for constructing brand audiences for targeting advertisements is provided, the method comprising: collecting visitation data relating to user-generated micro-content from a plurality of browsers; extracting a quasi-social network from the collected visitation data, wherein the quasi-social network comprises a plurality of links that are induced between the plurality of browsers visiting the user-generated micro-content; selecting seed nodes from the plurality of browsers, wherein the selected seed nodes have performed a brand action relating to the user-generated micro-content that is indicative of brand affinity; determining candidate nodes from the plurality of browsers based at least in part on a distance from the seed nodes in the quasi-social network; calculating a brand proximity score for each of the candidate nodes, wherein the brand proximity score includes one or more brand proximity measures and wherein the brand proximity score is an aggregated distance measurement between the candidate nodes and the seed nodes; generating a ranking of the candidate nodes based on the brand proximity score; and selecting a brand audience for serving an advertisement based on the generated ranking.
