Bone preparation tool kit and associated method
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.
