Patent ID: 8470049

Claim:
A femoral prosthesis comprising: an implant body having a proximal end and a distal end, the proximal end being dimensioned and configured to support a prosthetic neck, the implant body comprising: a shoulder at the proximal end, the shoulder being structured and dimensioned for a tight press fit into the neck of a femur; and a trunk at the distal end, the trunk comprising: a wedge formed by a tapered portion extending in the direction of the distal end of the implant body, and a medial column extending from the shoulder toward the distal end, the medial column disposed on a medial side of the wedge; a lateral column extending from the shoulder toward the distal end, the lateral column disposed on a lateral side of the wedge; the wedge, the medial column, and the lateral column to provide multi-planar stability for the implant body and surface area apart from the shoulder for fixation of the implant body with the femur; a medial column axis parallel to the long axis of the implant body, the medial column axis running through successive center points of the medial column; wherein an outer surface of the medial column has a lateral cross-section comprising an arc having a substantially constant radius from a center point of the medial column; and a medial cannula along the medial column axis; wherein the implant body has a substantially straight long axis so that the implant body does not curve into the diaphysis of the femur.
