Abstract:
1. A kit for reaming a portion of a long bone cavity for use in implanting a joint prosthesis, using a plurality of reamers for cooperation with portions of an orthopaedic implant component, the kit comprising: a distal reamer for reaming a distal portion of the long bone; a proximal reamer for reaming a proximal portion of the long bone; and a pilot shaft for insertion into a reamed distal portion and attachment to the proximal reamer during the reaming of the proximal portion; wherein 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 and the expandable body includes at least one gear and a cone, the gear engaging the cone, such that as the gear is rotated, the cone's increasing diameter forces the body to expand; wherein the expandable body includes an outer sleeve coupled to a pair of threaded screws, such that when the sleeve is rotated, the threaded screws extend into the expandable body, increasing the diameter of the pilot shaft.
