Patent ID: 8870875

Claim:
A system including set of rasps for preparing a bone to receive a prosthetic implant, the system comprising: a prosthetic implant having an outer surface geometry defining a size and a shape; a first rasp; and at least a second rasp; wherein the first and second rasps have a size and shape substantially congruent to the size and shape of the prosthetic implant, and wherein the first and second rasps differ in aggressiveness to achieve various levels of bone removal and bone compression, wherein each of the first and second rasps includes an anterior cutting surface, a posterior cutting surface, a medial cutting surface, a lateral cutting surface, and edges defined between the cutting surfaces, the first and second rasps having essentially identical cutting properties at corresponding edges and over corresponding portions of at least one of the medial and lateral cutting surfaces, the first rasp having more aggressive cutting properties than the second rasp over corresponding portions of at least one of the anterior and posterior cutting surfaces.
