Abstract:
1. A shoulder prosthesis comprising: a stem having a first longitudinal axis; an adaptor having a first portion including a first taper having a first taper axis of symmetry and a first diameter and a second portion positioned adjacent to the first portion and including a second taper having a second taper axis of symmetry and a second diameter, the first taper axis offset from and parallel to the second taper axis, the second diameter smaller than the first diameter, the first taper formed along the first diameter and the second taper formed along the second diameter; a plurality of indicia associated with the adaptor; and a head rotatably supported by the adaptor, the head having a semi-spherical articulating surface, and a third axis of symmetry of the head offset from and substantially parallel to the first taper axis and the second taper axis, wherein the head is coupled to the first taper and is positionable relative to the stem through rotation of the adaptor about the first taper axis for adjusting a radial offset of the head relative to the longitudinal axis of the stem and the plurality of indicia indicate an alignment of the radial offset.
