1. An orthopaedic implant system comprising:
a stem portion insertable into bone;
a mounting portion extending from the stem portion, wherein the mounting portion includes a first mounting bore extending inwardly from a first engagement face and a raised protrusion extending outwardly from the first engagement face, and wherein the raised protrusion tapers along a declined face toward the first engagement face;
a head portion adapted to mount an articulation member, wherein the head portion includes a head bore extending inwardly from a second engagement face and a recess extending inwardly from the second engagement face, wherein a periphery of the recess includes an inclined face sloping towards an opening of the recess along the second engagement face;
wherein the raised protrusion is insertable through the opening and into the recess such that the declined face and the inclined face abut each other in an installed position;
and
wherein the first mounting bore extends along a first mounting bore axis in a direction away from the raised protrusion such that the second engagement face slides across the first engagement face and such that the inclined face moves towards the first mounting bore axis to compress the inclined face against the declined face in response to securing a common fastener in the head bore and the first mounting bore.
