Abstract

A kit and associated method is for implanting a prosthetic device in a resected bone such as a humerus. The kit includes a trial assembly including a trial body portion having a trial bore defined therein, and a trial head portion having (i) a trail head member which includes a trial offset indicia, and (ii) an eccentrically located trial stem extending from the trial head member, the trial head stem being configured to be received within the trial bore. The kit also includes a final prosthesis assembly including a final body portion having a final bore defined therein, and a final head portion having (i) a final head member which includes a final offset indicia, and (ii) an eccentrically located final head stem extending from the final head portion, the final head stem being configured to be received within the final bore.
