Zusammenfassung: | A kit includes a number of femoral prostheses of different sizes and shapes. Each femoral prostheses in the kit includes a femoral stem including a proximal end portion defining a proximal stem axis, a femoral neck portion including a lateral shoulder extending distally and laterally at an angle relative to the proximal stem axis, such that when projected onto a coronal plane including the proximal stem axis, the lateral shoulder is not parallel to the proximal stem axis. Each prostheses further includes an insertion/extraction cavity extending distally from a proximal surface of the neck portion, the cavity defining an insertion/extraction cavity axis which, when projected on to the coronal plane, is not parallel with the proximal stem axis, and the lateral shoulder of each femoral prosthesis is oriented at an angle relative to the proximal stem axis that is different from the angle of each of the other femoral prostheses. |
