1. A prosthesis for filling a bone void within a femur, the prosthesis comprising:
a body including an aperture extending therethrough; and
first and second legs extending from the body, the first and second legs defining a space therebetween,
wherein the aperture is in communication with the space,
wherein the first leg includes a selectively removable portion such that the first leg is modifiable from having a first length with the selectively removable portion included to a second length less than the first length with the selectively removable portion removed,
wherein the first and second legs include respective first and second inner walls that define a space therebetween, the first and second inner walls including planar surfaces, and
the first and second legs include respective first and second outer portions separated from the space by the respective first and second inner walls, the first and second outer portions having greater porosity than the first and second inner walls.
