Patent ID: 7198642

Claim:
An orthopaedic system comprising a set of implant components sized and shaped to replace a portion of a bone, a set of trial components sized and shaped to replicate at least one feature of the implant components and a set of instruments for use in preparing the bone to receive the implant components, wherein at least one of the sets includes: a first member having a longitudinal axis; a second member having a longitudinal axis; and a retainer; one of the members having a male portion and the other of the members having surfaces defining a female portion; the female portion being capable of receiving the male portion to connect the first and second members together; wherein the female portion and the male portion are sized and shaped so that the male portion can be moved into the female portion through relative movement in a direction other than longitudinal; wherein the retainer is movable between an unlocked position wherein relative movement between the male portion and female portion is possible and a locked position wherein relative movement between the male portion and female portion is restricted; wherein the first member comprises a first spacer segment and the second member comprises a second spacer segment; where in the portion of bone to be replaced comprises an intercalary bone portion between two native ends of the bone and wherein the first member further includes a proximal stem component connected to the first spacer segment and the second member further includes a distal stem component connected to the second spacer segment, the proximal stem component including a stem sized and shaped to be received in the intramedullary canal of one native end of the bone and the distal stem component having a stem sized and shaped to be received in the intramedullary canal of the other native end of the bone; wherein the female portion is shaped to define a transverse slot; wherein the male portion comprises a transverse projection having a size and shape that complements the size and shape of the transverse slot of the female portion; and wherein the transverse projection comprises a pair of spaced parallel shoulders and a pair of spaced parallel intermediate walls adjacent to the spaced parallel shoulders, the spaced parallel intermediate walls defining undercuts.
