An orthopaedic shoulder prosthesis for replacing the humeral head of a patient's humerus. The prosthesis comprising a humeral head component (12) comprising (i) a generally hemispherically-shaped bearing surface, (ii) a backside surface opposite the bearing surface, and (iii) a tapered post (42) extending laterally away from the backside surface. The prosthesis also includes a stemless humeral component (10) comprising (i) a circular-shaped flange (14) (ii) an elongated sleeve (36), secured to, and extending laterally away from a bottom surface of the circular-shaped flange, the elongated sleeve having formed therein a tapered bore (40) configured to receive the tapered post of a humeral head component, and (iii) a number of cantilevered legs (16) extending laterally away from the bottom surface of the circular-shaped flange in the same direction as the elongated sleeve, wherein each of the cantilevered legs has one end thereof secured to the bottom surface of the circular-shaped flange, and in which the circular-shaped flange has a number of viewing windows (30) formed therein, the plurality of viewing windows is formed at a radial location between the elongated sleeve and the number of cantilevered legs.
