BONE PREPARATION TOOL KIT AND ASSOCIATED METHOD

摘要

A prosthesis (20) for use in performing joint arthroplasty is provided. The prosthesis (20) is to be fitted to a long bone (3). The prosthesis includes a first body (22) having a first body articulating surface (24) defining a generally circular outer periphery (26) of the first body articulating surface (24). The first body (22) has a support surface (28) opposed to the articulating surface (24). The support surface (28) is adapted to receive the head of the long bone (3). The prosthesis (20) also includes a second body (30) operably associated with the first body (22). The second body (30) has a second body articulating surface (32) extending from a portion of the circular outer periphery (26) of the first body articulating surface (24). A tool kit for preparing a humerus to receive a prosthesis is also disclosed.
