Abstract

A kit for reaming a portion of a long bone cavity for use in implanting a joint prosthesis, the reamers for cooperation with portions of an orthopaedic implant component. The kit includes a distal reamer for reaming a distal portion of the long bone and a proximal reamer for reaming a proximal portion of the long bone. The kit further includes a pilot shaft for insertion into a reamed distal portion and attachment to the proximal reamer during the reaming of the proximal portion. At least one of the distal reamer, proximal reamer, and pilot shaft is expandable, such that the at least one of the distal reamer, proximal reamer, and pilot shaft includes an expandable body adapted to adjust between a plurality of diameters.
