A system (10) for preparing a long bone for a prosthetic, the long bone having along axis comprises a distal instrument (12) and a proximal instrument (14).The distal instrument (12) is configured to remove bone from a distal portionof bone. The distal instrument (12) has a bone removing portion (16) configuredto remove bone along the long axis of the long bone and a shaft (18) extending fromthe bone removing portion (16) along the long axis of the long bone. The proximalinstrument (14) is configured to overlie the shaft (18) of the distal element(12) within the long bone. The distal shaft (18) guides the proximal instrument(14) to prepare the proximal portion of the long bone after the distal instrument(12) has prepared the distal portion of the long bone.
