<p>A tool (10) for preparation of a cavity (12) in a long bone (14) for receiving a joint prosthesis (16) for use in arthroplasty includes a body (20) having an outer periphery (22) of the body (20). The outer periphery (22) is adapted to have a first shape (24) and a second shape (26) thereof of the body (20). The second shape (26) has dimensions different than the first shape (24), whereby the tool (10), when in the first shape (24), is capable of forming a first cavity (30) in the long bone (14) and whereby the tool (10), when in the second shape (26), is capable of forming a second cavity (32) in the long bone (14). The second cavity (32) is different than the first cavity (30). <IMAGE></p> |
