Patent ID: 8852189

Claim:
A kit for use in joint arthroplasty comprising: an orthopaedic implant stem of a joint prosthesis; and a reamer assembly for reaming a proximal portion of a cavity for implanting a proximal component of a the joint prosthesis, said reamer assembly cooperating with a proximal portion of the orthopaedic implant stem, said reamer assembly comprising: a sleeve defining an inner periphery, said sleeve configured to fit over the proximal portion of the orthopaedic implant stem, said sleeve defining an outer periphery; and a proximal reamer including a body defining a reamer cavity formed therein for receiving at least a portion of the outer periphery of said sleeve, a plurality of cutting edges extending outwardly from said body, said cutting edges adapted for cooperation with bone, and a stem extending from an end of the body, wherein the sleeve comprises a locking feature and the stem comprises a connection feature to removably secure the sleeve to the proximal portion of the orthopaedic implant stem when assembled together, wherein the proximal portion of the orthopaedic implant stem includes threaded portion; the inner periphery of the sleeve defines a sleeve cavity extending completely through the sleeve, the sleeve cavity configured to allow the threaded portion to pass through the sleeve when the sleeve is fit over the proximal portion of the orthopaedic implant stem; and a guide pin configured to fit on the proximal portion of the orthopaedic implant stem, wherein the guide pin is configured to threadably engage the threaded portion, wherein the reamer cavity includes a proximal portion sized and shaped complementary to a proximal portion of the guide pin.
