1. A femoral augment for implantation with an orthopedic implant device in a bone, the femoral augment comprising:
an augment wall having an outer portion and an inner portion, the inner portion defining an inner region of the augment, the inner region being sized to receive placement therein of a stem of the orthopedic implant device, and the outer portion having an outer surface;
wherein the inner region extends along a central axis;
wherein the outer portion has a proximal end, a distal end, an anterior side, a posterior side, a medial side, and a lateral side;
wherein the proximal end has a first size and a first shape;
wherein the distal end has a second size, which is different from the first size, and a second shape, which is different from the first shape;
wherein the medial side or the lateral side extends at a first oblique angle, relative to the central axis;
wherein the anterior side extends at a second oblique angle, relative to the central axis;
wherein the first oblique angle is different from the second oblique angle;
wherein at least one of the first shape and the second shape is an oval shape;
wherein the augment wall comprises a relief, which is a portion of the augment wall that has a reduced thickness as compared to other portions of the augment wall, the relief defining and forming the outer surface of the portion of the augment wall where the relief is located, the relief comprising at least a first sidewall and a second sidewall that extend over the outer surface of the augment wall;
wherein the augment wall has a first thickness, the reduced thickness of the relief being less than the first thickness;
wherein the first sidewall and the second sidewall both are formed contiguous with the proximal end and extend away from the proximal end in a direction of the central axis; and
wherein the first sidewall and the second sidewall are angled relative to each other, such that the first and second sidewalls are not parallel to each other.
