Claim Text:
1. A method, comprising: machining a neck body formed of solid metal to include a base portion, to include a neck portion that extends outwardly from the base portion and that has an end with a cylindrical shape that engages a femoral component, and to include an elongated male protrusion that extends outwardly from the base portion and that has a cylindrical shape that tapers; fabricating, separately from the neck body, a bone fixation body with an elongated tapering body with a bow, with a trapezoidal shape in a horizontal cross-sectional view, with a proximal end including an opening, and with a porous metal structure that extends throughout the bone fixation body with the porous metal structure having a size and a shape that emulate a size and a shape of a porous structure of natural human bone; and connecting, after the bone fixation body is separately fabricated from the neck body, the bone fixation body to the neck body to permanently attach the bone fixation body to the neck body and create a hip implant, wherein the elongated male protrusion extends into the opening of the bone fixation body, forms a core for the bone fixation body, extends toward a distal end of the hip implant, and includes a section with a non-circle shape in a cross-sectional view of the hip implant in order to provide an anti-rotational interface between the neck body and the bone fixation body, wherein the porous metal structure of the bone fixation body permanently attaches to an exterior surface of the elongated male protrusion to create the hip implant before the hip implant is implanted.
